A skylit sanctum

Had your fill of all that sunshine on the Algarve coast? From the beach at Benagil you can hire a boat, pilot your own kayak, or—if you're really adventurous—swim out to the fantastic sea caves carved into the rocks just offshore. The Atlantic Ocean has been working on the architecture here for a very long time indeed. Visitors to this exquisitely rugged part of the Portuguese coastline are treated to surreally textured rock stacks, weathered pinnacles, and cavernous limestone 'rooms' carpeted by soft sand and surrounded by turquoise waters.
