From remote jungles and idyllic islands to snorkelling with luminous plankton and a temple shaped like an elephant, readers share their discoveries
The Surin islands in the Andaman Sea about 50km from the mainland are surrounded by coral reefs and considered the best snorkelling destination in Thailand. There are numerous day trips but to really experience the magic, stay a few nights at the back-to-basics campsite at Mai Ngam bay, a perfectly formed horseshoe bay. Spend your days hiring longboats captained by locals to take you to snorkelling hotspots such as Suthep Bay, Thailand’s first underwater sign-marked snorkelling trail.
