The clear blue seas are a great place to do some scuba diving, and there are many diving schools operating along Chaweng beach, as well as plenty of opportunities to go hiking and mountain biking through the island's interior.
Most hotels and resorts offer a comprehensive programme of water sports from their beaches, and the warm blue waters are an excellent place to sail and windsurf, or indeed to just swim.
There are a couple of golf courses available on the island, which allow non-members to play on a daily basis provided that they book in advance.
