St Michael’s Mount Causeway Fishing

Last updated: 6 days ago

St Michael’s Mount Causeway Fishing Map

A tidal stone causeway linking Marazion to St Michael’s Mount, bordered by mixed ground of cobbles, kelp-fringed rock and adjacent clean sand in Mount’s Bay. Best fished on a flooding tide and into dusk when baitfish and predators work the current lines along the causeway edges. Expect snags close in but clean sand lies just off to either side. Very slippery weeded stones and rapidly rising water make timing and footwear critical—never get cut off. Busy with visitors at low water; fish away from pedestrians and respect local/NT guidance. Parking and amenities in Marazion are close by, and the scenery is outstanding.

St Michael’s Mount Causeway Fishing

Summary

St Michael’s Mount Causeway sits in Mounts Bay at Marazion, Cornwall, linking the mainland to the National Trust island at low tide. The boulder-strewn scars and sand gullies around the causeway draw baitfish and predators, offering excellent lure and light-tackle opportunities for bass, wrasse, garfish and more. It’s a photogenic, productive mark when timed to the tides, but it’s also busy and fast-flooding, so planning and etiquette are essential.

Location and Access

Access is straightforward via Marazion on the A394, with multiple seafront car parks and a short, level approach to the beach. The granite causeway itself is exposed around low water; you’ll be walking on uneven cobbles, boulders and firm sand.

Seasons

This is a mixed ground mark with classic Mounts Bay species. Expect bass-focused lure fishing, wrasse in the rough, and summer surface action.

Methods

The ground dictates tactics: weedless soft plastics over kelp, shallow divers and topwaters on the flood, and light bottom gear on cleaner sand tongues.

Tides and Conditions

This mark is all about timing. The best windows often coincide with the first push of flood around boulder edges and the last of the ebb as gullies drain off the flats.

Safety

Treat this as a dynamic tidal crossing with real cut-off risk. It’s also a busy tourist route—angling etiquette and public safety come first.

Facilities

You’re next to a popular seaside town, so facilities are good by Cornish standards. Expect seasonal variation and peak-time queues.

Tips

Subtlety and timing out-fish brute force here. Think light, stealthy, and mobile.

Regulations

Rules here are a mix of general English sea angling law and site-specific access etiquette. Always check current notices on-site and official sources before you fish.
