Benagil Sea Cave

Benagil Sea Cave in the Algarve is a true natural wonder. It's a sea cave with a natural occurring oculus that towers over its own secluded beach. At the right time of day the Sun casts light through this dome, illuminating a stunning scene that anyone visiting Portugal should try to see.
