Dive-site story
Collywell Bay sits along the Northumberland coastline just south of Seaton Sluice. Divers navigate a rocky shore entry into a series of shallow kelp beds, rock gullies, and mixed sand patches that shelter typical temperate North East marine life. The site is sheltered from moderate westerly breezes but remains vulnerable to North Sea easterly swells.
Extensive kelp gullies and rocky reefs providing habitat for crustaceans
Easy shore access across the bay during calm conditions and high tide
Opportunity for macro photography among the under-boulder fauna and red algae
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Late spring through early autumn provides warmer water and more consistent periods of settled sea state.
