The South Beach is made up of two miles of golden sand, stretching from St Catherine's Island to Giltar Point. The beach is backed by sand dunes leading to the the oldest established golf course in Wales and looks out toward Caldey Island. The South Beach has won a Tidy Britain Group Seaside Award as well as the well respected Blue Flag.

At the north end of the beach can be found hire facilities, toilets (with disabled access) and a car park. A new complex is currently under construction so facilities are currently limited. Lifeguards operate daily (10am-6pm) throughout the summer.

Between the period 1st May to 30th September, dogs should be kept on a lead on the area of the South Beach nearest the town, however no restrictions apply on the majority of the South Beach so great for those with dogs.  There is no pontoon.
