Fishing at Caernarfon
Fishing the Menai Strait from the harbour and marina walls below the castle, with fast tides and rough ground that punch above their weight for bass and conger.
📍 View on the mapWhat you can catch → Full fish guide
| Species | Season | Method |
|---|---|---|
| Bass | May–Oct | best fished on a rising tide with lures or bait as the strait's current picks up |
| Grey Mullet | Jun–Sep | light float tackle with bread or small bait in the harbour, though they're easily spooked |
| Conger Eel | May–Oct | heavy tackle and fish bait fished after dark around the walls |
| Flounder | Sep–Mar | worm bait fished hard on the bottom in the harbour |
Tactics
The Strait runs hard, so fish states of the tide rather than fighting the full ebb or flood; crab and ragworm are the standby baits on the rough, snaggy ground.
Best tide: Rising tide · Best time: Summer evenings
