About Castle Beach:

Situated in the heart of Falmouth, Castle Beach is one of our most popular survey sites. At low tide, the shingle beach gives way to a wide expanse of rockpools, home to a huge range of biodiversity. The marine life is so good here that at high tide, castle beach provides an excellent snorkelling location and the wreck offshore is a well-known dive site.

The Rock Pool Project at Castle Beach:

Castle beach is home to two of our survey sites- Castle Beach North and Castle Beach South. The beach is joined at low tide with other Falmouth survey sites at Tunnel Beach and Gyllyngvase.
