Koh Nang Yuan is a small island off the west coast of the diving destination island of Koh Tao in Thailand. It’s owned by the same guy who’s the master behind the inescapable Chang beer. You’ll want at least a half day to visit Nang Yuan when you’re in the area, but you’ll probably want to kick back for a little longer.
Koh Nang Yuan is actually made up of three little islands connected by an enormous sandbar. The snorkeling is some of the most spectacular in all of Thailand (don’t stand on the coral, it’s alive!). There are no cars on Nang Yuan, it’s a pedestrian paradise.
