Being the home of St Catherine’s Island, Castle Beach is very popular with people wanting to take a look at the historic fort. The rock face is accessible at low tide but getting on the island itself, is not something that is accessible to the general public.
A boat service also runs from here which sets off on a 20-minute journey to Caldey Island. Most people access this beach from the slipway that is accessible from the top of the harbour. The slipway offers toilet facilities along with a cafe so you can grab a bite to eat.
A lifeguard service operates over the summer between 10am – 6pm
