Llyn Berwyn

A calm upland lake surrounded by conifer trees, with flat rocks in the foreground on the near shore, under a partly cloudy sky.

Berwyn sits apart from the Teifi Pools cluster that Tregaron AA is better known for, out on its own patch of moor above the town, holding a population of wild brown trout that see remarkably little pressure.

How to fish it · for Trout
When
Late April–June; evening rises through summer
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Keep a sedge-style dry or emerger on a short leader for the evening rise.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Keep a sedge-style dry or emerger on a short leader for the evening rise.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

About this water

Berwyn sits apart from the Teifi Pools cluster that Tregaron AA is better known for, out on its own patch of moor above the town, holding a population of wild brown trout that see remarkably little pressure. There's no shared ticket gimmick or reservoir bundle here — just a lake, a walk, and fish that have to work for a living in thin upland water. Cymdeithas Pysgota Tregaron keeps the access simple, which suits a venue like this: nothing to overthink, nothing to oversell. If the Teifi Pools lakes are the club's headline water, Berwyn is the quieter answer for anyone who'd rather not share the bank with anyone at all.

Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • Sedge is in its seasonal window, boosting the chance of targeted feeding.
