Koh Samui

Koh Samui is Thailand's third-largest island, ringed by palm-fringed beaches like Chaweng and Lamai and dotted with coconut plantations, hillside temples, and a laid-back mix of backpacker bars and upscale resorts. It sits in the Gulf of Thailand alongside neighboring party island Koh Phangan and diving hub Koh Tao, making it a natural base for island-hopping.

Getting thereMost travellers fly directly into Koh Samui Airport (USM), an open-air terminal on the island's northeast coast served by Bangkok Airways with routes from Bangkok (~70 minutes) and a handful of regional cities; a slower, cheaper alternative is flying or taking an overnight train to the regional hub of Surat Thani and then connecting via ferry (~1.5+ hours by sea, plus transfers) to the island's main pier at Nathon.
How long to stayPlan on ~3-4 days to settle into beach life, explore a couple of viewpoints or temples, and take a day trip to nearby islands like Koh Phangan or Koh Tao.
