My Experience Fly Fishing in Wales

I’m currently based in Northern Ireland, and have extensive experience in fly fishing in Wales. I regularly take the ferry from Dublin to Holyhead, making this journey at least four times a year.

The waters I’ve had the privilege of fishing in Wales are exceptionally clear, and I’ve had the rare opportunity to sight-fish for trout, an uncommon experience in the UK.

I’m always impressed by the abundant population of brown trout on my fishing trips in Wales. On one of my recent trips, I even had the thrill of landing a 10lb Atlantic salmon. Wales holds a special place among my favorite fly fishing destinations worldwide, and in this post, I’ll tell you why.

Why Fly Fish in Wales?

Unlike other destinations where rivers can be overcrowded, Wales boasts numerous rivers and streams to choose from thanks to its stunning mountain ranges.

This abundance means you’ll have plenty of untouched water to explore during your fishing adventures in Wales.

10 Best Trout Rivers in Wales

Wales has numerous pristine rivers, perfect for a wide variety of fly fishing techniques and styles.

Fly fishermen in England primarily target the wild brown trout in these rivers which is a difficult yet very rewarding catch.

River Dee

The river Dee is well known for its great population of wild brown trout, located close to the town of Llangollen in the North of Wals. Furthermore, no 4×4 is required to fish this river, and the Elk Hair Caddis and Pheasant Tail Nymph are well-known successful flies commonly used in this location. 

River Taff

The river Taff is a river I like to call a ‘hidden gem’. Although it’s not popular, it’s extremely good for targeting brown trout and is situated close to Cardiff.

Furthermore, the Taff’s open fields make the river fantastic for impaired anglers or beginners learning how to cast. The Black Gnat is a well-known fly to use here. 

River Usk 

The river Usk is a well-known trout river located close to Brecon that fishes well with a dry fly pattern known as the Adams Irresistible.

Furthermore, the river Usk has developed the nickname “The Lady of the Stream” due to its crystal clear, waters, making it a favorable spot for many Welsh fly fishermen.

River Teifi

The river Teifi is located close to Lampeter and is known for its diverse water conditions; from gentle streams to fast-flowing rapids. If you’re looking for the largest brown trout in Wales, this is a good location to try. Many anglers know the Teifi to hold very large fish that can be caught on Royal Coachman flies. 

River Wye

The river Wye is located close to the border between England and Wales, offering a range of creeks and tailwater sections best fished with an Adams Parachute. The river Wye is well known for its famous wye salmon as well as its impressive brown trout.

River Clwyd

The river Clwyd, situated near Ruthin, offers some of the best fishing in Wales for brown trout. While fishing with a Gold Ribbed Hare’s Ear, you can admire the superb castles along the river bank.

River Dovey (Dyfi)

The Dovey (otherwise known as the Dyfi), is located in the middle of Wales. The Dovey is famous for its large run of sea trout which can be easily caught on a Zulu fly in late June and early July.

River Conwy

It should be noted that a challenging river to fish due to its drastically changing water levels is the river Conwy. However, despite it’s difficulty, it’s a fantastic spot to target brown trout when the conditions are correct. Conwy is situated close to Wale’s largest mountain, Snowdonia.

River Mawddach

The river Mawddach, situated near Barmouth, is a brilliant location to target brown trout in Wales using Orange and Coch-y-Bonddu flies. However, I’ve heard from other anglers there are numerous pesky trout-eating otters that run this river so keep an eye out when fishing it.

River Teifi 

The Teifi Pools are made lakes created from the Teifi river and form the only location in this list that I recommend using a 4×4 to get to. This river is located in the Cambrian Mountains and fishes well using a Red Tag fly.

10 Best Trout Lake Lakes in Wales

Wales not only boasts numerous fantastic trout rivers but also offers a considerable abundance of brown trout lakes. In this section, we’ll dive into my top ten trout lakes in Wales.

Lake Tegid (Bala Lake)

Lake Tegide, otherwise known as Bala Lake, is located near the small town of Bala in Wales. The open environment of this lake makes it easy to access and is great for beginner fly anglers who haven’t perfected their roll casts. This lake does not require the use of a 4×4 and fishes well with an elk hair caddis fly.

Lake Brenig

Lake Brenig is located in Denbighshire, close to the town of Cerrigydrudion. It’s home to a healthy population of brown trout that are usually caught on daddy long legs. Furthermore, Brenig is well known for its fantastic rises in summer months. 

Lake Clywedog

Clywedog is located in the hills of Powy and holds very large trout that can be caught using pheasant tail nymphs. While a 4×4 is not essential, there is a steep drive up to this lake. 

Lake Gwyn

This lake, located in Conwy Valley, is home to the famous Welsh poet Taliesin. Lake Geirionydd has brown trout and can be accessed without a 4×4. 

Lake Nantlle Uchaf

Nantlle Uchaf is located in Snowdonia. Local anglers praise this lake as being one of the best for dry fly fishing in all of Wales. I personally recommend using a parachute adams on this lake. 

Lake Padarn

Padarn is near the small town of Llanberis, and you can access it without needing a 4×4. Lake Padarn fishes well with a teal blue and silver or bloody butcher.

Anglesey and the North Wales Coast 

Anglesey is Wales’ largest island, and offers an exceptional fly fishing experience, particularly along the north coast of Wales, which is perfect for targeting sea bass on the fly. This rugged coastline is home to a significant population of sea bass that can be effectively pursued using sand eel patterns.

Wales Fly Fishing – Fish Species

There are over ten species that are commonly targeted in Wales on the fly. In this section, I’ve created a curated list of the most common species to target in Wales on a fly rod:

Brown Trout

Brown trout can be targeted all over Wales. They are native to rivers streams and lakes and they can be caught using Kate McLaren and Black Pennell flies.

Atlantic Salmon 

Atlantic Salmon are viewed as the most prized fish to land on a fly in Wales. Wales has a good run of Atlantic Salmon from June through to September. 


Sea trout are brown trout that have swum to the sea and returned to the base of the river. They are typically silver in color and can occasionally be mistaken for small Atlantic salmon.


Pike are notoriously strong fish to catch on the fly. Most anglers target them with an 8-weight fly rod and use flies that imitate the local perch. Furthermore, they can be targeted all year round on the fly.

Mackerel are sometimes seen as a beginner’s fish to target. However, they provide excellent sportfishing opportunities in Wales and put up a fantastic fight for their size. I highly recommend them as a sportfish to target.


Pollock can be found on the Welsh coastline year-round. Although they typically grow to around 2 pounds in weight along the coast, they have been known to reach over twenty pounds.


These fish are sometimes confused with Pollock, but the key difference is that they have a straight lateral line and exhibit green tinges throughout their scales. Coalfish can be successfully caught using various sand eel fly patterns.

July offers exceptional salmon fishing across Wales. During this month, the majority of Atlantic salmon have entered the river systems to spawn, and they are present in significant numbers; providing excellent angling opportunities.

Wales Fishing Report

During my recent trip to Wales, I had the pleasure of landing a remarkable 10lb wild Atlantic salmon. This fish displayed beautiful brown colors, indicating it had been in the river system for an extended period. I was thrilled with the fight this Welsh salmon put up and was left absolutely buzzing with excitement.

In the same week, I also had the pleasure of landing several brown trout, each weighing over 3lb, which was another rewarding experience.

On the way back to catch the ferry for my return to Ireland, I made a stop at the coastline and was able to pick up some small local pollock from the harbor using a 4# fly rod. Overall, a very mixed species trip, and I will definitely be returning this coming year.
