Down to Dive
If you are traveling Thailand you have to try your hand at SCUBA Diving. Koh Tao, an island in the gulf of Thailand is the cheapest place in the world to learn, with calm, clear waters and the occasional whale shark sighting this is the perfect place to take your first breaths underwater. Avoid the huge shops and head back from the beach a bit for smaller more intimate learning. Rocktopus Divers, just up the hill from Sairee beach is a great one. And Koh Tao has more than just diving, a small sports company called Good Time Adventures offers a rock climbing course and zip-lining over the beaches (they also have a killer jalapeno burger). All over the island food is good and cheap, and if you are into nightlife it cannot be beat!
