Fishing Lake Geneva (Lac Léman): the fish, the seasons, and the plan to catch them

What and where it is

Lake Geneva, known locally as Lac Léman, is a huge crescent-shaped alpine lake on the river Rhône, shared between Switzerland (Vaud, Geneva and Valais) and France (Haute-Savoie). It is the largest lake in Western Europe by volume: about 580 km², 73 km long, and up to about 310 m deep. Deep, clear and cold.

The lake sits at about 372 m altitude and holds roughly 89 billion m³ of water, which makes it far bigger than anything else in the region (figures from the lake's geography and the CIPEL water commission). It splits into two parts that fish quite differently. The Grand Lac is the broad, very deep central and eastern basin off Lausanne, Évian and Montreux, where the deep-water fish live. The Petit Lac is the narrower, shallower south-west arm running down to Geneva and the Rhône exit, which warms faster and holds good shoals of perch.

The depth is the thing to plan around. Much of the Grand Lac drops away to well over 100 m, so the bank fishing works the margins, the harbour walls and the drop-offs, and the deep water is boat country. The water is cold and clear, which keeps the fishing precise: the fish feed in low light and hold deep in bright weather.

It is an easy lake to reach and to base yourself on. Geneva has an international airport and mainline rail; Lausanne, Nyon, Morges and Montreux are all on the Swiss lakeside line; the French resorts of Thonon-les-Bains and Évian sit on the south shore. Most visiting anglers base themselves at Geneva, Nyon or Lausanne on the Swiss side, or at Thonon or Évian on the French side.

This is a busy lake, used by ferries, sailors and swimmers as well as anglers, so it is bright and crowded in high summer. That shapes the fishing: the early and late windows are when it is quiet and the fish feed. The whole lake is governed by a single Franco-Swiss regulation, renewed for 2026 to 2030, so the rules are broadly the same wherever you launch, even though you buy your permit from one canton or the French shore.

The fish, and where, when and how to catch each

Perch is the everyday fish, from the bank and the boat. Féra is the prize on the table. Arctic char and lake trout are deep-water boat fish. Pike and zander hold along the shallows and reed edges. Each one holds at a different depth, moves through the year, and wants a different method. The cards below give you where, when and how for every species in scope.

Others, for context. The lake also holds roach, bream, tench, carp and the occasional larger predator. Several coarse species are eaten in the region, but the six cards above are the trip for most visiting anglers. Whatever you target, the keep-don't-return rule for perch, char and trout is the thing to read before you fish (see what you can keep).

I have set each species out as a card. Read the one for the fish you want, then check the seasonal section for how its depth moves through the year, and follow the rig link to build the method.

How the fishing changes by season

Winter and early spring are deep-water work for char, féra and trolled trout, with pike before the spring closure. Late spring opens perch after its closure and brings pike back. Summer is the classic perch boat fishing on the shoals, fished dawn and dusk. Autumn fishes well for perch and pike before the char and féra close for spawning.

Here is the year in plain terms, tied to the depths from the cards above.

• Winter (December to February). Deep-water work. Char and féra hold deep in the Grand Lac and come to the gambe over the right ground; lake trout come to trolling near the surface and the breaks. Note the autumn-into-winter closure on char and féra (roughly mid-October to the end of December), so the deep gambe fishing reopens in the new year. Pike fish the margins in the cold.
• Spring (March to May). Pike fish the shallows until they close for spawning (roughly the first three weeks of April), then reopen. Perch is closed for its spawning (roughly the first three to four weeks of May) and reopens at the end of the month. Plan around these closures rather than turning up and finding your target shut.
• Early summer (late May and June). Perch reopens and the shoals come on. Pike are back along the reed edges and bays. The lake is warming and brightening, so the first and last hours are when the fish feed.
• High summer (July and August). The classic perch boat fishing: find the shoals over the drop-offs and on the structure, work them on the drop shot or the gambe at dawn and dusk. The middle of a bright, busy day is slow. Char and féra hold deep for the boat angler with a sounder.
• Autumn (September to mid-October). Often the best all-round window. Perch and pike feed up before the cold, and the deep fish are still open until the char and féra close in mid-October. Then the deep season pauses for spawning and the year turns back to trolled trout and the cold-water margins.

What you can keep (and the keep-don't-return rule)

Léman has an unusual rule that overrides the usual release habit. Under the lake regulation, every perch, char and trout you catch on rod must be kept and may not be returned, even if it is under 15 cm. You may not cut the head or tail off a fish before you get home, so it can be inspected. Féra is the prized eating fish; pike and zander are kept within their limits.

This is the standout point of the whole water, so it is worth being exact. It is the opposite of the catch-and-release instinct most anglers travel with, and it matters from the first cast.

So this is not a water where you return undersized perch out of habit. If you catch it on a rod, it comes home. That changes how you fish: keep a cool box, fish for the table, and do not target perch, char or trout if you do not intend to keep them.

The rest is straightforward. Féra (the whitefish) is the prized eating fish of the lake, and pike and zander are kept within their size and bag limits (see the next section). Everything has a minimum size and a daily quota, so check the table before you keep a fish. Whatever you keep, handle fish in wet hands, keep the kit clean between waters so you do not carry anything from one lake to the next, and respect the quotas.

Licence and rules

Yes, you need a Léman lake permit. Buy it from one of the Swiss cantons (Vaud, Geneva or Valais) or, on the French shore, via the Haute-Savoie federation. The short-term permits are cheap and tourist-friendly: a Geneva day permit is about CHF 10 for 2026. A new Franco-Swiss regulation took effect in 2026, setting harmonised sizes, quotas and closures, plus the keep-don't-return rule above.

How the permit works. Léman is governed by one Franco-Swiss regulation, but you buy your permit from whichever shore you fish: the Swiss cantons of Vaud, Geneva or Valais, or the French shore through the Haute-Savoie federation. A short-term tourist permit lets you fish from the bank or a boat with the standard tackle for the chosen technique. Choose the shore you will fish from and buy that side's permit.

Swiss-side permit prices (Geneva, 2026), via ge.ch (as of 5 June 2026). Geneva sorts its permits by technique, with the everyday lake permit covering the gambe (the float-and-fly perch fishing), and a separate, dearer category adding trolling:

• Non-resident surcharge: adults not resident in Geneva canton pay a 50% surcharge on the lake permit (so a day permit is about CHF 15 for a visitor). (Source: ge.ch, as of 5 June 2026.)
• The SaNa attestation: the annual Swiss permits require a Sachkundenachweis (SaNa) competency certificate. The day and month permits do not, which is why the day permit is the visitor's pick. (Source: cantonal permit pages.)

Vaud (the north shore from Nyon through Lausanne to Montreux) sells short-term lake permits online, ordered and printed at home, and longer permits for residents and visitors. The Vaud annual lake-trolling (traîne) permit is CHF 140 for residents and CHF 210 for non-residents in 2026; buy short-term day and week permits online at vd.ch. Confirm the exact Vaud day and week lake tariff there before you buy. (Source: vd.ch 2026 price table, as of 5 June 2026.)

French shore (Haute-Savoie). The French Léman card is sold via the Haute-Savoie federation (pechehautesavoie.com) and cartedepeche.fr, or from a local dépositaire (tackle shop). The trolling option (traîne) is an extra of about €35 and is open to members of the French Léman anglers' association (APALLF). Confirm the current French-shore tourist and annual Léman tariffs at pechehautesavoie.com before you buy.

How to get it

• Decide which shore you will fish from (a Swiss canton, or the French shore).
• Swiss side: buy a Geneva permit through the Pêche GE service (online or a tackle shop for the day permit), or a Vaud permit online at vd.ch. Pay and print or carry it on your phone.
• French side: buy the Léman card at cartedepeche.fr or pechehautesavoie.com, or from a local tackle shop. Add the trolling option if you will troll.
• Carry the permit (paper or phone) while you fish, and a catch logbook if your permit requires one.

Sizes and quotas (2026)

Source: the Haute-Savoie federation's Léman size-and-limit table, under the 2026 Franco-Swiss regulation, as of 5 June 2026.

• The keep rule again: perch, char and trout caught on rod must be kept, even below the minimum size, and may not be returned (see what you can keep). The minimum size is a keep-and-cook threshold here, not a "put it back if it is smaller" line.
• Zander is fished along the shallows; confirm its current Léman minimum size and quota with your canton or the federation before you keep one (it is managed under the same regulation).

2026 closures

The spring spawning closures and the autumn-into-winter salmonid closure. Source: pechehautesavoie.com and the lake-law summaries, as of 5 June 2026.

The pike closure is the one date that differs by shore, so plan an April pike trip around the shore you will fish. So spring has two staggered closures: pike in April (longer on the French shore), perch for most of May. The deep char and féra fishing pauses from mid-autumn to the year's end. Summer and early autumn are the broad open window for perch, with the deep fish open until the autumn closure.

Other rules that matter

• The keep-don't-return rule for perch, char and trout, and no cutting head or tail before home (above).
• Lines and technique are set per permit category (the gambe permit covers the everyday float-and-fly fishing; trolling needs the trolling permit/option). Buy the category that matches your method.
• Clean your kit between waters so you do not move invasive species or disease between lakes.

Where to fish from the bank

From the bank, perch is the main fish, with pike and zander along the margins. The reliable spots are the harbour walls and quays at Geneva, Nyon, Morges and Lausanne (Ouchy) on the Swiss shore, and the resort shorelines at Thonon-les-Bains and Évian on the French shore. The Petit Lac toward Geneva holds strong perch shoals.

The lake drops away fast off the Grand Lac, so from the bank you are fishing the margins, the harbour corners and the drop-offs. These are the dependable bank areas:

• Geneva harbour walls and the Rhône exit. The quays and harbour walls around the city, and the shallower Petit Lac arm running down to the Rhône, hold good perch shoals close in. The simplest base for a bank perch session, and where you can pick up a guided boat.
• Nyon. Harbour and shoreline marks on the Vaud shore, a quieter base than Geneva, with good perch and pike water nearby.
• Morges. Harbour walls and quays, productive for perch and a pleasant base midway along the north shore.
• Lausanne (Ouchy). The Ouchy quays and the lakefront, with deep water close in and easy access; also the departure point for guided trips.
• Thonon-les-Bains and Évian (French shore). Resort shorelines and harbour areas on the south shore, with bank perch and pike fishing and the French Léman card sold locally.

What depth means for method from the bank

• Harbour corners, quays and shallow margins (a few metres): perch, and pike along the reed edges and bays. A drop shot hovering a lure off the bottom, or a sliding float rig with bait.
• The drop-off, where the bottom falls away (about 5 to 15 m): the productive seam. Perch patrol it. A slip-float paternoster holds bait just off the bottom; a drop shot reaches it too.
• Reed edges, bays and harbour mouths in low light: pike and zander feed. The pike rig with a lure or deadbait on a trace, or a heavier drop shot for a low-light zander.

The deep-water fish, féra and char, hold over water too deep to reach from the bank, so they are boat fishing. From the shore, plan a perch trip (with pike and zander along the margins) and fish the first and last hours of light.

Bank vs boat, and the time of day

From the bank, target perch (and pike and zander along the margins) at first and last light, on a drop shot, a float rig or the pike rig. From a boat you add féra, char and trolled trout over deep water, found with a sounder and worked on the gambe or the troll. The middle of a bright, busy day is usually slow either way.

Plain version: if you only have the bank, fish perch at dawn and dusk and work the margins for a pike or a low-light zander. With a boat you keep all of that and add féra, char and trolled trout in the deep water, which is what most people travel here for. Morning tends to edge evening for perch; the predators often switch on as the light goes.

This table is the core decision the trip turns on. It lives on the cheat sheet too. Read it as: pick your fish, pick where you are and when, and it gives you the rig.

The boat: guided, hire, or your own

A boat opens up féra, char and trolled trout, so it is worth one even for a short trip. The simplest route on Léman is a guided day from Geneva, Nyon or Lausanne, with the boat, tackle and permit supplied. You can also hire a boat to fish yourself. Trolling needs the trolling permit (or the French trolling option), and a powered boat needs the Swiss boating competency.

A guided boat is the realistic way to reach the deep fish on a first visit, because finding féra and char depends on a sounder and local knowledge of the basin. Watch the wind: Léman gets the strong south-westerly vent and the bise from the north-east, which can build fast and make the open lake dangerous, so check the forecast before you go out.

Guided (recommended for a first visit)

Professional guides take you out and supply the boat, tackle and permit, covering perch on the gambe and lures, and féra, char and trout by trolling or the deep gambe. Book directly:

• Romandie Fishing (departs Port d'Ouchy, Lausanne) – romandiefishing.ch. 4-hour and 8-hour sessions, permit and tackle included; 2026 rates run from about CHF 290 to CHF 1,150 depending on the session and group size (confirm when you book). Pike from May, perch from June, lake trout January to April.
• Genevaboats (departs Geneva, Lausanne and Montreux) – genevaboats.ch. Trolling or casting for perch, pike, lake trout, char and féra, with a fully equipped boat (GPS, sounder, downrigger, rods) and daily permits available; rates on request, so book through the site.

Hire a boat

Boats can be hired at Geneva, Nyon and the lakeside ports for a self-guided session, often with fishing tackle included. Confirm the rate, whether a Swiss boating licence is needed, and the permit you must hold when you book (a powered boat over a certain size needs the Swiss boating competency).

Launch your own

Public launch ramps sit at the lakeside towns on both shores. A powered boat needs to meet the Swiss (or French) boating rules and the lake's navigation regulations; confirm the local ramp and any launch fee with the harbour before you go.

Where to stay (and buy a permit locally)

Base yourself near the fishing on whichever shore you will fish. Geneva, Nyon, Morges and Lausanne (Ouchy) on the Swiss north shore put you on the perch marks and the guided-trip departures; Thonon-les-Bains and Évian on the French south shore are quieter resort bases. You can buy a permit online or from local tackle shops on either shore.

Stay near the water

• Geneva – easiest for the airport, the Petit Lac perch marks and a guided trip from the city.
• Nyon and Morges (Vaud) – quieter lakeside towns midway along the north shore, on the perch and pike water, with short-term Vaud permits online.
• Lausanne (Ouchy) – the lakefront at Ouchy, with deep water close in and the Romandie Fishing departure point.
• Thonon-les-Bains and Évian (Haute-Savoie) – French-shore resort bases, with the French Léman card sold locally and quieter shorelines.

Buy a permit in person at tackle shops on each shore (for example GiantFish and other Vaud dépositaires sell short-term Swiss permits; Geneva tackle shops sell the day permit; French-shore tackle shops and dépositaires sell the Léman card via cartedepeche.fr). Confirm a local shop near your base before you travel, or buy online (above).

The methods, and the rigs to build them

The everyday fishing is covered by the existing rigs, which share most of their tackle. Drop shot is the all-rounder for perch and zander, bank and boat. The float rigs present bait from the bank. The vertical jig is the boat method for zander. The pike rig adds a trace. The gambe is for perch, féra and char. Trolling and shore fly add the trout and the deep char. Each links to its own build page.

Map of fish, where and when, to a rig. The build instructions and the knots live on the rig pages, so I link rather than repeat them.

• Perch, from the bank, first and last light → drop shot. A lure hovering just off the bottom, worked actively. The most versatile rig here, and the one to learn first. Lighter weight from the bank, heavier from a boat.
• Perch on bait, from the bank → sliding float rig. Presents maggot or worm at a set depth over deep water. A bobber stopper sets the depth, so you fish deep but still cast and land.
• Perch holding deep, tight to the bottom over a drop-off → slip-float paternoster. A slip float sets the depth; a dropper loop holds the bait just off the bottom while a small weight anchors it.
• Zander (and perch) from a boat over the drop-offs → vertical jig. A jighead and a soft plastic dropped straight down and worked with a lift-and-drop. Gets you down fast and keeps contact in deep water and wind.
• Pike, bank or boat → pike rig. A wire or heavy fluorocarbon trace, then either a big soft shad on a jighead (lure version) or a deadbait under a float (bait version). The trace is the one non-negotiable for pike.
• Perch, féra and Arctic char on the gambe, mostly from a boat → gambe / sabiki. A string of small flies or nymphs on droppers with a weight on the end, lowered to the shoal the sounder shows. The everyday Léman perch method, and the way to reach féra and char in the deep water.
• Lake trout and deep char by trolling → trolling. Spoons and lures pulled near the surface or set deep with leadcore or a downrigger. A specialist boat method; book a guide and the trolling permit.
• Trout from the shore on the fly → fly fishing. A streamer fished from the shore for cruising trout where the lake allows it. See also the dry fly and nymph approaches.

The three knots that tie the everyday rigs are the Palomar (the workhorse), the dropper loop (the paternoster and the gambe) and the non-slip loop (jigheads and lures). Each rig page links to the knots it needs.

Build your kit (the kit builder and the shopping list)

Pick your fish and whether you are on the bank or in a boat, and the kit builder trims the shopping list and the rigs to exactly what you need. One light spinning outfit and a small box of terminal tackle build the everyday rigs; the gambe adds a soft second rod, and trolling and fly fishing are guided add-ons. The full list is below, grouped, with no brands and no prices.

That is the everyday list. One rod, one 2500 reel, one spool of braid, one spool of leader, and a small box for the swivels, hooks, weights, jigheads, floats and soft plastics. Add the light second rod and a sabiki for féra. Trolling and shore fly are specialist add-ons, easiest as a guided day, so the guide supplies the trolling gear. A cool box matters here, because of the keep-don't-return rule: perch, char and trout you catch come home, so pack to keep your catch cold. Buy generic sizes and types; you do not need a named brand to catch a perch.

A trip checklist

Before you go: check your dates against the closed seasons, decide which shore and buy that side's permit (with the trolling option if you will troll), read the keep-don't-return rule, decide bank or boat and book the guide or hire, pack the one shared kit and a cool box, and note the sizes and quotas. Then print the cheat sheet and take it with you.

Do this in order:

1. Check your dates against the seasons. Confirm the fish you want is open on your days (the "what's on" strip above). Pike closes 1 to 20 April, perch 1 to 25 May, and the deep char and féra close from mid-October to year's end. Summer and early autumn are the broad open window.
2. Decide the shore and buy the permit. Swiss side: a Geneva day permit (about CHF 10, plus 50% for non-residents) or a Vaud short-term permit online. French side: the Léman card at cartedepeche.fr. Add the trolling permit/option if you will troll. Carry it while you fish.
3. Read the keep-don't-return rule. Perch, char and trout caught on rod must be kept, even undersized, and may not be returned; do not cut the head or tail before home. Fish for the table, and pack a cool box.
4. Decide bank or boat, and book it. Bank only: target perch at dawn and dusk, and the margins for pike and zander. Want féra, char or trolled trout: book a guide (Romandie Fishing from Ouchy, or Genevaboats) or hire a boat, and check the wind and the Swiss boating rules.
5. Pack the one kit. Rod, 2500 reel, braid, fluoro leader, the small terminal box, soft plastics, net, bucket and a cool box. The shopping list above (trimmed by the kit builder) is your packing list. Add the light rod and a sabiki for féra.
6. Note the sizes and quotas. Trout 50 cm (4/day), char 30 cm (8/day), féra 37 cm (10/day), pike 50 cm (2/day), perch 15 cm. Keep perch, char and trout you catch; handle fish in wet hands.
7. Print the cheat sheet and fold it into the box. Get the printable cheat sheet

Common mistakes

The big ones: turning up in a spring closure with pike or perch shut, expecting féra or char from the bank, fishing the bright middle of a busy day, returning undersized perch out of habit (which the rules forbid here), buying the wrong permit category, and ignoring the wind on the open lake.

• Fishing a spring closure by accident. Pike closes 1 to 20 April on the Swiss shore (and right through to 10 May on the French shore), perch 1 to 25 May, on staggered dates. Check before you book, not after.
• Expecting féra or char from the bank. Both hold over deep water and are boat fish here, found with a sounder. Bank-only is a perch trip, with pike and zander along the margins.
• Returning undersized perch, char or trout. On Léman the rules require you to keep them, even below 15 cm, and not cut the head or tail before home. This is the opposite of the usual release habit, so fish for the table and pack a cool box.
• Buying the wrong permit category. Geneva sorts permits by technique: the everyday lake permit covers the gambe, and trolling needs the dearer category. On the French shore, trolling is an extra option. Buy the category that matches your method, and remember the 50% non-resident surcharge on the Swiss side.
• Fishing the bright middle of a busy day. This is a clear, deep, busy lake. A sunny midday is slow. Fish the first and last hours.
• Bringing the wrong line. Braid main line with a fluorocarbon leader is what makes the clear-water perch and zander fishing work. For pike, a wire or heavy fluoro trace is essential, because pike teeth cut a light leader.
• Ignoring the wind. Léman gets strong south-westerly and bise winds that build fast on the open lake. Check the forecast before you launch, and respect the navigation rules.

Frequently asked questions

The questions travelling anglers ask most about Lake Geneva: what is here, the cross-border permit, prices, the keep-don't-return rule, the seasons and closures, bank versus boat, the best bank spots, the boat, the limits, and the kit.
