Castle Beach (Pembrokeshire)
This beach is definitely unique for its structure, with the beach being split in two at low tide to make way for St Catherine’s Island and a very old fort.
As the Sunday Times’ Beach of the Year 2019, this beach is not only popular for its reputation but also for its strange architecture. You can access the fort from the stone gateway of tarmac running down from the stranded island. Castle Beach is the smallest of the three beaches in Tenby, measuring only 150m wide and even narrower at high tide.
When the tides are low, it also connects directly to South Beach with its sloping band of dry sand.
