Tywyn Point is at the extreme south-western end of Pembrey Sands, within the boundaries of the RAF's area of the beach. Access is restricted - usually to late afternoon / evenings and weekends. Wooden poles topped with orange tetrahedrons mark the boundaries, and red flags are flown from these poles when the firing range is in use - otherwise, this remote end of the beach is open.
The shore is sandy, backed by low dunes, and the RAF firing range - with plenty of signs warning not to enter. The estuary of the Gwendraeth marks the north-western end of the beach, and swimming is dangerous due to currents. The sand continues around the point, where the shore is sheltered and a good choice for sunbathing - very few people venture this far up the beach. There are millions of shells here - mostly razors, otter shells, rayed trough shells and cockles, and also a substantial wreck. The sand finally ends at a saltmarsh, and there is no way off at this end. The nearest parking is at Pembrey Country Park - 5 miles away along the beach. It's best to bring a bike!
