Quick answer

Koh Samui, Thailand's second-largest island, is ringed by a coastal road of about 50 km linking a dozen beaches, from busy Chaweng and Lamai on the east coast to quieter Bophut, Maenam and the sunset-facing west. Coconut plantations and forested hills fill the interior, with waterfalls and viewpoints. Samui's weather pattern differs from the Andaman coast: it is driest from about February to August, and wettest from October to December. Plan 6 days for a first visit; the best months are February–April and June–August.

Getting there and around

Samui International Airport, an open-air terminal owned by Bangkok Airways, is in the north-east of the island, about 10–15 minutes from Chaweng and Bophut. Flights are limited, so many travellers fly to Surat Thani and take a combined bus and ferry, about 3–4 hours in total.

A ring road of about 50 km circles the island, connecting all the beaches. There is no public transport beyond shared songthaews, so visitors rely on taxis, ride-hailing apps, scooters or rental cars.
