Koh Kradan, Thailand
As is the custom with tropical beaches, the powdery sand is to be expected. The place is also excellent for snorkeling, with a reef just off the beach. There are also hammocks and of course, crystal-clear waters.
If you’re looking to do some exploration, you can rent a kayak to go around the whole island and go to the more isolated spots. You can also take longtail boat trips to other places, such as Ko Waen, Ko Chueak, and Ko Muk’s Emerald Cave.
