Fishing in Wales

By Alex Clayton · Updated 24 October 2026

In most of Wales, you cannot legally keep a salmon you catch on rod and line. That is the first rule to know about fishing in Wales, and it is not the rule in England. Beyond it, you need an England and Wales rod licence if you are 13 or over, plus permission from whoever owns the water.

The salmon rule comes from the Welsh rod and line byelaws, which cover every Welsh river except the Dee, Severn and Wye. Those three cross the border and run under their own byelaws.

According to Fishing In Wales, the country has more than 500 lakes and reservoirs and about 2,700 km of coastline, with wild trout rivers and sewin runs in between.

Below you will find which fishery suits you, the licence, the salmon and sea trout rules, sewin, the llyns, the border rivers, sea fishing and tickets. One warning: the Welsh byelaws date from 2017 and their text says they stop having effect on 31 December 2026, so check the current position with Natural Resources Wales.

Game, Coarse or Sea: Which Kind of Welsh Fishing Suits You

Visitors break Welsh fishing rules without meaning to: a worm rod on a sewin river in April, or a trout and coarse licence on a salmon beat. Pick your fishery first, then check its rules.

Each of the four broad types needs a different amount of homework:

Type	Typical quarry	Licence you need	Rules homework	Best for
Game rivers	Brown trout, sewin, salmon, grayling	Salmon and sea trout (trout and coarse for brown trout and grayling only)	High	Experienced fly anglers
Stillwater trout	Stocked rainbows, wild and stocked brown trout	Trout and coarse	Low	First fly fishing trips, families
Coarse	Barbel, chub, dace, pike, perch	Trout and coarse	Medium	Coarse anglers on holiday
Sea	Sea fish from the shore	None for sea fish (salmon and sea trout if you target sea trout)	Low to medium	A cheap first taste

Game fishing on rivers is the classic Welsh draw, and it carries the most rules: the licence type, the byelaws and each river’s own seasons. Grayling keep river fly fishing going into the colder months after the trout season ends.

Stillwater trout fishing is the gentlest route into fly fishing in Wales. A trout and coarse licence plus a fishery ticket covers you, as the llyns and reservoirs section below explains.

Coarse anglers get the Wye, and Fishing In Wales counts about 170 coarse fisheries across the country. Sea fishing from the shore needs no rod licence at all, unless sea trout are your target.

If you are new to fly fishing, start on a stocked llyn or reservoir. If you want the trout fishing Wales is known for, plan a summer sewin trip and read the salmon and sea trout rules section first.

Do You Need a Fishing Licence in Wales

If you already hold an Environment Agency rod licence from England, it covers Wales too. Wales has no separate licence.

According to GOV.UK, you need an England and Wales rod licence to fish for salmon, trout, freshwater fish, smelt or eel with a rod and line in Wales. That includes private waters, such as a farm pond or a syndicate lake. Anyone aged 13 or over needs one. Licences for juniors aged 13 to 16 are free, and children under 13 need no licence.

Which licence you buy depends on the fish:

Trout and coarse: covers coarse fish and non-migratory trout, so brown and rainbow trout.
Salmon and sea trout: needed for sewin and salmon.

These were the prices on GOV.UK when this guide was checked on 24 October 2026:

Licence	1-day	8-day	12-month
Trout and coarse (2 rods)	£7.30	£14.70	£36.80
Trout and coarse (3 rods)	n/a	n/a	£55.30
Salmon and sea trout	£13.50	£30.50	£93.10
Concession 12-month (aged 66 and over, or disabled)	n/a	n/a	£24.50 trout and coarse, £62.00 salmon and sea trout

Prices change each April, so check GOV.UK before you buy.

Buy online at GOV.UK, where a Welsh-language version is available, up to 30 days before you want the licence to start. You can also phone the Environment Agency on 0344 800 5386, Monday to Friday, 8am to 6pm.

Fishing without a licence can bring a fine of up to £2,500. A licence does not give you the right to fish a particular water, though. You still need a ticket or the landowner’s permission, which the tickets section at the end of this guide covers. For the different licence types in more detail, see how the rod licence works.

For a summer sewin week, buy the 8-day salmon and sea trout licence.

Salmon and Sea Trout Rules in Wales: What You Can Keep and How You Can Fish

You can fish for salmon on almost any Welsh river, but you can’t take one home. That single rule shapes salmon fishing in Wales, and it changes the tackle you tie on.

The rules come from the Wales Rod and Line (Salmon and Sea Trout) Byelaws 2017, made by Natural Resources Wales (NRW). They apply to Welsh rivers except the Dee, Severn and Wye, which run under their own byelaws. If you plan to fish for salmon on either border river, read our guides to fishing the River Wye and the River Dee, then check that river’s own rules.

Rule	Salmon	Sea trout
Keeping fish	Removing any salmon caught on rod and line without NRW’s written authority is an offence. Returning it straight away is lawful.	None may be removed before 1 May on 23 named rivers, including the Tywi, Taf, Teifi, Dyfi, Usk, Neath and Glaslyn. None over 60cm, measured from snout to the end of the tail, may be removed anywhere in Wales.
Bait	No bait at all	A single worm only, on a single barbless hook with a gape no bigger than 8mm
Hooks	Barbless or de-barbed. No trebles.	Barbless or de-barbed. No trebles.

In practice, that means fly or lure for salmon, with the barbs flattened, and a plan for returning every fish. Barbless hooks also make unhooking quicker, so the fish goes back stronger.

Is this still current?

The 2017 byelaws state that they cease to have effect on 31 December 2026. When this guide was checked in October 2026, we could not confirm whether they will be renewed or replaced, so check the current rules with Natural Resources Wales before every trip.

Individual rivers also set their own seasons and method dates. A 2020 Fishing Passport guide to the Tywi, for example, gave a later start date for worm fishing for sea trout than for the season itself. That is a dated illustration, not current advice. Seasons vary river by river, so this page gives no dates. For how seasons work, see our guide to fishing seasons.

Before you set up, flatten your barbs and check the river’s own rules.

Sewin Fishing: Why Welsh Sea Trout Draw Anglers at Night

The best sewin fishing often starts after the light goes, on rivers that look empty all day.

Sewin is the Welsh name for sea trout. They are brown trout that go to sea to feed and return to their home rivers to spawn, bigger and brighter than the river trout that stayed behind.

Where and when

Fishing In Wales names the Dovey (Dyfi), Teifi and Towy (Tywi) as the principal sewin rivers. All three are on the byelaw list of rivers where no sea trout may be kept before 1 May.

According to the same source, the larger fish run earlier, from March and April. The main run follows from late June through July and August. Timing shifts with rainfall and river levels, so watch the water rather than the calendar.

Day or night

By day, fish wet flies as a spate falls and clears. After dark, fish low, clear water, when sea trout that held still through the daylight start to move.

Guide Steffan Jones, writing for Fishing In Wales in 2020, suggests a 10ft rod for a #7 line, and nothing lighter than 12lb at night. You can’t see where a hooked fish is heading in the dark, so stronger line gives you a margin near snags.

Before a night session:

Walk the pool in daylight and note the snags and deep holes.
Know your way out before dark.
Fish with a companion where you can, and carry a head torch.

The byelaws still apply after dark: barbless or de-barbed hooks, no trebles, the single-worm rule and no fish over 60cm kept.

Sewin ask more of you than a stocked stillwater, with more rules and later nights, but they are the fishery Wales is best known for.

Trout Fishing on Welsh Llyns and Reservoirs: North, Mid and South

The simplest way into fly fishing in Wales is a stillwater with a day ticket. You need a trout and coarse licence and a fishery ticket, and the salmon and sea trout byelaws don’t come into it for brown and rainbow trout.

Trout fishing in Wales on stillwaters splits into two kinds of water. A llyn (Welsh for lake) up in the hills usually holds small wild brown trout, often after a long walk in, and the weather decides the day. Stocked reservoirs and fisheries hold bigger fish, usually with a lodge, easier access and, on some waters, boats.

North Wales

The north has the mountain llyns and some of the country’s larger lakes, so you can choose between a hill walk to a wild water and a day on bigger stocked water. Our guide to trout lakes in North Wales covers the options.

Mid Wales

Mid Wales is quieter country, with upland waters and reservoirs that rarely feel crowded. Start with our guide to trout lakes in Mid Wales.

South Wales

In the south, reservoirs and fisheries sit within easy reach of the M4 corridor and the valleys, which suits a day trip. See our guide to trout lakes in South Wales.

Getting started

On big, exposed water, look for wind lanes and fish the bank the wind is blowing towards, where food collects. On Windermere I’ve found that reading the wind matters more than the fly on the end, and I’d expect the same on any large, open llyn. As a starting point, try an intermediate line with small wet flies or buzzers, then change depth until you find fish.

Each fishery sets its own rules on catch and release, barbless hooks, bag limits and seasons, so read the ticket before you start.

Best for first fly fishing trips and families. Skip it if you specifically want sewin or salmon. Check with the fishery before you travel.

Coarse Fishing and the Border Rivers: The Wye and the Dee

Visit Wales’ own fishing guide calls the Wye the best coarse river in the UK. That is an opinion, not a measurement, but its barbel and chub fishing explain why people make the claim.

The Wye

According to Visit Wales, the Wye holds barbel, chub, dace and grayling, with pike and perch too. For stretches, methods and access, see our River Wye fishing guide. Coarse fishing there needs a trout and coarse licence and a ticket or permit for the stretch you fish.

The Dee and other rivers

The Dee is the other big border river, and our River Dee fishing guide covers it in detail. Visit Wales also lists the Taff and the Severn for coarse fishing in Wales.

Why the border rivers need their own homework

The Dee, Severn and Wye have their own salmon and sea trout byelaws, separate from the 2017 Wales byelaws described above. The rules on returning salmon, treble hooks and bait may be set differently there. If you plan to fish for salmon or sea trout on any of the three, read that river’s own rules first.

Coarse anglers have one more thing to check. River coarse fishing has a close season, and the dates depend on where you fish, so this page gives none. Our fishing seasons guide explains how they work.

For coarse fishing in Wales, start on the Wye. For salmon on the border rivers, start with their own byelaws.

Sea Fishing in Wales: Free Shore Fishing and What to Check

You don’t need a rod licence to fish for sea fish from the Welsh shore. Visit Wales describes shore fishing as free, and Fishing In Wales puts the coastline at about 2,700 km, so there is no shortage of marks.

“Free” has limits, though:

Sea trout: if you target sea trout from the shore or in an estuary, you are fishing for a migratory trout. The salmon and sea trout licence and the byelaws above apply.
Access: piers, harbours and private foreshore can carry their own rules or charges. Check locally before you set up.
Keeping fish: sea fisheries rules such as size limits and bass rules are set separately, and we have not listed them here. Check NRW and the Welsh Government before you keep anything.

Boat fishing is a different matter: charter trips are paid, so expect to book and pay per person or per boat.

If you want a cheap first taste of fishing in Wales, a shore session on a rising tide costs you nothing but bait.

Tickets and the Fishing Passport: Getting Permission to Fish

Much of the best river fishing in Wales is private or club water, and finding out who to ask is the hard part.

Your rod licence makes you legal. GOV.UK is clear that you also need the landowner’s or fishery’s permission.

The Fishing Passport

The Fishing Passport is an online booking system run on a not-for-profit basis by the Wye & Usk Foundation. It covers waters across Wales and the Marches and offers three kinds of booking:

Day bookings for single visits.
Season or club bookings for regulars.
Private bookings arranged with the owner.

Owners keep control of their fisheries, so each beat keeps its own rules. A coarse pass has been announced for winter 2026/27, so check the site for details.

Other routes in

Fishery day tickets for llyns and reservoirs, bought at the lodge or online.
Angling club membership, usually the cheaper option if you fish one area regularly.
Hotel and estate water, sometimes available to guests.
Local tackle shops, which often sell club day tickets.

Before you book, check the beat’s rules on methods, catch and release, and seasons, which can be stricter than the byelaws. For the rest of the country, see our guide to UK fishing regions.

Best for visitors who want river beats without joining a club. Skip it if you’re fishing a stillwater with its own day ticket. Check with the fishery before you travel.

Frequently asked questions

Do I need a licence to fish in Wales?

Yes. Anyone 13 or over needs an England and Wales rod licence to fish for freshwater fish, trout, salmon or eel in Wales, and it is free for juniors aged 13 to 16. It is the same licence used in England. You also need permission from the fishery, club or landowner.

Can I keep a salmon caught in Wales?

Not without written authority from Natural Resources Wales. Under the 2017 Welsh byelaws, any salmon caught on rod and line must be returned straight away. The Dee, Severn and Wye have their own byelaws. The 2017 text says it ceases to have effect on 31 December 2026, so check the current position with NRW.

When is the best time for sewin fishing?

According to Fishing In Wales, the main sewin run is from late June through August, with bigger fish arriving earlier in March and April. Under the byelaws, no sea trout may be kept before 1 May on 23 named rivers, and none over 60cm may be kept anywhere in Wales.

Is sea fishing free in Wales?

Mostly. You need no rod licence for sea fish from the shore, and Visit Wales calls shore fishing free. Targeting sea trout needs a salmon and sea trout licence, though. Piers, harbours and private foreshore can have their own rules or charges, and sea fisheries limits still apply.

When does the fishing season start in Wales?

It depends on the river, the species and the water. Seasons are set locally, so we have not printed dates. Check with Natural Resources Wales and the fishery or club before you go, and read the ticket or club rules for any local close season.
