Llyn Coron is Anglesey's principal stillwater — a shallow, fertile limestone loch that sits quiet in the island's pastoral landscape. Managed as a dedicated fly-fishing venue, it produces reliable brown and rainbow trout on buzzers and nymphs. The shallow nature means fish are often visible, so presentation matters. Daphnia blooms in summer can produce spectacular buzzer hatches. Bank fishing only; the compact scale rewards methodical coverage over distant casting. A water that says 'come spend time here' rather than 'come kill fish' — exactly right for the thoughtful angler.

The plan
Plan A
Work a bushy searching pattern on the bob and drop a contrasting nymph 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.
Boat — at anchor
Windy conditions suit anchoring in productive areas rather than open-water drifting.
