Llyn Crafnant

Llyn Crafnant lake surrounded by forested hills near Trefriw, Conwy

Llyn Crafnant sits in the Conwy Valley beneath the Carneddau — a real mountain water accessible from a quiet village, historically fished from the bank in a moorland setting with wild browns and stocked rainbows over spring olives and buzzers.

How to fish it · for Trout
When
No strong hatch signals at the moment — general searching tactics should work best. Drift conditions look good — cover the wind lanes.
Where
Set up a broadside drift and cover the water systematically. Work Cormorant on the bob and Autumn Buzzer on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Cormorant on the bob and Autumn Buzzer on the point.

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

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Boat-friendly, competition-influenced, often wind-driven, with strong top-of-water periods but also classic deep searching and washing-line phases.

About this water

Important honesty note: the fishery and its lakeside café closed as of June 2026 — fishingwales.net posted an explicit closure notice, but the operator's own legacy website still shows old opening times and season dates with no mention of the closure, so don't trust that page. Older pricing and access details circulating elsewhere predate the closure. Confirm current status directly before planning a visit.
