Tenby South Beach stretches about a mile from the town to Giltar Point and looks out towards Caldey Island, about 2 miles offshore. A car park is located behind the beach and access to the shore is a short walk over the sand. Toilets and drinking water are available, and a bar / restaurant and ice-cream parlour (both with outdoor seating) have recently opened at the back of the beach.
The beach itself is made up of sand and some pebbles (mostly limestone, sandstone and shales) backed by dunes which are covered in sea buckthorn. Being east facing, offshore winds occur frequently, so inflatable craft should be used with caution. A strong rip current occurs near Giltar Point. The southern end of South Beach is known as Penally Beach and is a 5 minute level walk along a tarmac footpath from Penally railway station, which has a small (free) car park and toilets.
Surf conditions can be good here on a big swell and when other beaches are blown out. It's a good beginners beach and also popular with windsurfers. Lifeguards patrol at the town end from Easter until early September (10am - 6pm) and a dog ban operates between the beach access point and Castle Beach, 1st May to 30th September.
Tenby has excellent facilities, including two Information Centres, pubs, cafes, hotels, B&B's, shops, a supermarket and a railway station (about 10 minutes walk).
