Why you'll love it
Koh Samui is Thailand's second-largest island, in the Gulf of Thailand, with palm-lined beaches, jungle hills and plenty of spa resorts. It scores 9 out of 10 for beaches and romance, and 8 for wellness and safety, which makes it a popular choice for honeymoons and relaxed couples' trips.
The best time to visit Koh Samui is January to March, when skies are clear and the sea is calm. Samui follows a different weather pattern from Phuket, with its wettest months around October and November. Ang Thong Marine Park closes for part of that season.
Chaweng is the liveliest beach, Lamai is a little more relaxed, and Bophut's Fisherman's Village is known for its evening market and restaurants. The top day trip is Ang Thong Marine Park, an archipelago of 42 islands with kayaking and snorkelling. The Big Buddha temple is a landmark.
Koh Samui suits couples, honeymooners and wellness travellers.
