Amari Palm Reef Resort, Moo 2
An efficient, professional diving school that offers PADI (Professional Association of Diving Instructors) certifications. You can keep it easy here and have the team teach you basic skills for breathing with scuba and snorkeling gear. Or you can go deeper with an intensive two- or three-day course for PADI certification. When you're ready to go into the deep crystalline waters, ask your dive master to take you to Chumphon Pinnacle, where you'll see white-eyed moray eels and great barracuda.

It's impossible to see all of the temples in Thailand, so choose wisely. On Samui, the Lamai temple, just a five-minute drive from popular Lamai Beach on the island's east coast, should be a priority. It’s a striking example of the ornate gold structures in the country that seem to transcend time. Locals come to pray and offer gifts to the Buddha. A nearby museum store sells artifacts and offers an impressive history of the city and island. Wear respectful, conservative clothes—no bare arms or legs—and comfortable shoes to allow for plenty of walking around the grounds.
