Just back from a week in Tenby and swam at Castle Beach daily. Castle Beach and South Beach are joined except when the tide is fully in. Very long sandy beach. The water is beautifully clean, with some strong waves at times although surfers dont tend to surf there. More of a family Beach. On calmer days I swam around the old fort on St Catherine's Island. If you are really strong you could maybe swim over to Caldey Island.
Location
