Another view point for Tor Bay. There is great walking to be had here when the tide is out. The views are great, and the Little Tor and Great Tor, along with nearby Three Cliffs are super nice rock climbs.

This route provides amazing views and access to a lesser crowded beach option than Oxwich Bay Beach. Beaches best visited during low tides but not essential.
