Treyarnon Bay Fishing

Last updated: 1 week ago

Treyarnon Bay Fishing Map

Treyarnon Bay is a west-facing sandy beach with rocky headlands and gullies at either end, offering mixed-ground fishing. The surf beach produces bass in a rolling sea, while the kelp-fringed rocks to the north and south hold wrasse and pollack. Summer brings mackerel, garfish and scad to the points on clear, calm evenings; winter and nights see dogfish and the odd ray from the cleaner sand. Dabs, flounder and the occasional sole are taken at short to medium range over the flat sand. Access is straightforward from the nearby car park with short walks to either side. Best conditions are a building or easing swell on a flooding or first of the ebb, with dusk and dawn particularly productive. Hazards include strong surf and rip currents, swell on the rocks, the risk of cut-off around the headlands at mid to high tide, slippery weeded ledges, and lesser weever fish in summer—wear boots and check tides carefully.

Treyarnon Bay Fishing

Summary

Treyarnon Bay sits between Constantine Bay and Porthcothan on Cornwall’s exposed north coast, offering a mix of sandy surf and rocky headlands. It’s a versatile mark: bass in the breakers, wrasse and pollack off the rocks, plus the chance of summer mackerel and the odd ray after dark. Anglers come for the scenery and the variety—just pick your ground to match the conditions.

Location and Access

Getting there is straightforward from St Merryn, with clear signage to Treyarnon Bay and a pay-and-display car park close to the beach. The terrain ranges from level beach to uneven rocky headlands; plan your approach according to the tide and swell.

Seasons

A classic mixed-ground venue, Treyarnon produces surf bass, rough-ground wrasse and pollack, and seasonal pelagics. Expect different fishing depending on whether you’re on the beach or rocks.

Methods

Choose your approach by ground and conditions: surf tactics for the beach, finesse or stout gear on the rocks. Lures score consistently for mobile anglers; bait excels in darkness or coloured water.

Tides and Conditions

Treyarnon is highly state- and swell-dependent. Read the beach and headlands before committing, and avoid exposed ledges in big Atlantic swell.

Safety

This is an exposed Atlantic venue with real hazards. Respect the sea, the tide, and the lifeguarded swimming zones.

Facilities

Facilities are better than many wild marks, especially in summer. Expect seasonal services and plan outside peak months.

Tips

A little local knowledge goes a long way at Treyarnon. Use the tide to reveal structure and plan your return.

Regulations

Rod-and-line sea angling is permitted at Treyarnon Bay. There are no local byelaws banning fishing from the beach or rocks, but a few key rules and good practices apply.
