The beaches are long with soft sand and are great for light water sports like SUP and kayaking-but are just a short kayak away from a beautiful reef for snorkeling. With this, the beaches are quiet and the few resort options allow for a special retreat. Con Dao is often overlooked as a beach destination in Vietnam, and I almost don’t want to share it so it stays that way! Located off the Southern Coast of Vietnam, Con Dao is a smaller island with very little commercial development.
