Llyn Hir

A long, dark upland lake curving through open moorland hills under a cloudy sky, viewed from a rocky rise above its shore.

Hir means long, and it's the most literally descriptive name in the Teifi Pools group — a narrower, more elongated lake than its rounder neighbours, which changes how you fish it more than you'd think.

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.

Bank

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

About this water

Hir means long, and it's the most literally descriptive name in the Teifi Pools group — a narrower, more elongated lake than its rounder neighbours, which changes how you fish it more than you'd think. Wild browns, same headwater character as Egnant and Teifi itself, but the shape gives you more bank to cover and more variety of water in a single visit. Same club, same access up through Tregaron, same exposed, weather-driven fishing that defines the whole plateau. If you're working the pools as a circuit, Hir is worth a longer stop than its size alone would suggest — the shoreline does more work than the acreage implies.
