The area around Rhoscolyn and Trearddur Bay is one of the most popular sea-diving areas in North Wales. The dive information here is taken from Chris Holden's excellent book "Underwater Guide to North Wales, Vol One: Barmouth to South Stack" (see below for reference).

The area around Rhoscolyn Beacon "is excellent for marine-life enthusiasts, with sun stars, yellow boring-sponges, and dead-men’s fingers, while the rocky gullies in the more sheltered areas are totally covered in feather stars. Most diving here is in the 10-15 metre range where there is a wide variety of fish life." There are conger eels in small caves and a family of seals living around the islands.

The area has also attracted many wrecks over the centuries. 'To the south of the tower, more scattered wreckage is possibly all that remains of the Elizabeth Kloosterboer, a small dutch schooner wrecked here in March 1878. Chains, hinges, bricks, copper bars and hull sheathing are often seen during a dive.
