Ko Samet is small and is essentially an island for relaxing and enjoying the quiet life close to nature. As more tourists arrive, more facilities and outdoor pursuits are being offered, particularly along the more developed northeast coast at Hat Sai Kaeo (Diamond Beach) Ao Pai, and Vong Deuan. Sailing, snorkeling, boats for hire and windsurfing can all be arranged through many of the resorts. Windsurfing is particularly good north of Hat Sai Kaeo and the rocky north coast where strong currents and offshore winds offer a challenge. Windsufers are available at most guest houses for around 100B to 200B per hour) You can also rent jet-skis at Hat Sai Kaeo.

For around 300B per person, you can book a speedboat at the main beaches. Take a tour around the island and/or go snorkeling off the rocky uninhabited western side, or around the reefs at the southern tip. They'll be happy to do a morning drop-off and afternoon pickup if you want to relax at one the secluded bays along the island's east coast. Or negotiate a price and explore the islands of Kudi, Kruai, Kham and Plai Tin which lie a little to the east of Ko Samet. The islands are fringed by lovely beaches - ideal for swimming and camping. Scuba diving excursions can be arranged at Vong Duang.

The beaches on the southeast coast are the least developed and least visited. The west coast is rocky but does have one very secluded beach Ao Prao (Paradise Beach) which has a comfortable bungalow resort and a alternative health centre offering courses in yoga, painting, dance, meditation and Reiki healing among others. Courses conducted in English.
