The Ang Thong Marine National Park
Around 42 islands make up the Ang Thong National Marine Park, northwest of Samui. Geographically different, this fascinating group of islands have spectacular limestone formations, caves, lagoons and beautiful beaches. Many islands are uninhabited with bays and colorful coral formations. Other islands rise from the sea as dramatic walls of rock hundreds of metres high. Besides the many small coves and secluded beaches, erosion has shaped some interesting formations which give some of the islands their names, such as 'Sleeping Cow Island' and 'Three Pillar Island'. Accessible on day trips by boat.

Koh Phangan
Famous for its Full Moon Parties, Koh Phangan also offers a beach lifestyle, "New Age" culture, inexpensive local Thai food, and relatively cheap accommodation. It's a place to go walking, snorkelling, swimming, or try new things. From belly dancing courses to Full Moon parties, to lazing on the beach or snorkelling. It's all about taking it easy and leaving mainstream life behind.

Ko Tao
"Discovered" by travellers in the 80's Ko Tao has been gradually gaining popularity. More remote than Samui, faster and safer boats now allow easier access to the island and new resorts with 24 hour air-conditioning are adding to the old basic bungalows. Since the main attraction is diving - the beaches remain tranquil and uncrowded. Check out the underwater scenery - it's what Ko Tao is famous for! Sharks, stingrays, pufferfish, various groupers and triggerfish are just some of the locals. The east of the island has some of the best snorkelling sites - spectacular coral reefs, sea fans and colourful fish.
