Agios Pavlos, on the island of Crete, is a remote fishing village with only a couple of tavernas and guest houses.
It's the type of place you'd go to spend a lazy afternoon on a tiny boat with a local fisherman, and then learn how to wrap your fish in fig leaves and lemon and grill it with his grandfather.
It's rugged and unspoiled. You can hike about 20 minutes down a very steep sand dune to a completely secluded beach. Because of the hike, bring plenty of sun creme and water as there is literally nothing at the beach except for a couple of locals, who may or may not be nude.
The snorkeling is amazing—crystal clear water with hundreds of fish, rocks, and caverns to explore.
Agios Pavlos is probably going to stay this way for years.
