Start from Wembury National Trust car park and from the entrance turn down the slipway to the beach. The coastal path will take you behind the beach and along the cliff tops. You will follow the coast past HMS Cambridge and onto Heybrook Bay where you can return back the way you came or head slightly inland and follow the perimeter path around HMS Cambridge and pick up the coastal path again further on. The walk is about 3 miles, and is quite hilly and can be muddy underfoot.
