FAQ
Frequently asked questions about Koh Samui
What are the best things to do in Koh Samui?
The must-sees are Ang Thong National Marine Park, Fisherman's Village in Bophut, Silver Beach (Crystal Bay). Also worth your time: The Big Buddha and Wat Plai Laem, Chaweng and Lamai beaches, Na Muang waterfalls, A day trip to Koh Tao and Koh Nang Yuan.
How many days should I spend in Koh Samui?
Allow 4 to 5 days to enjoy the beaches, take a trip to Ang Thong Marine Park and stroll around Fisherman's Village. If you're combining it with Koh Phangan or Koh Tao (frequent ferries), 3 days on Samui is enough.
Koh Samui or Phuket, which one to choose?
Koh Samui is quieter, more family-friendly and more wellness/spa-oriented, with a very convenient international airport. Phuket offers more accommodation choices at every budget and faster access to Krabi, Phi Phi and Khao Sok. For a relaxed first beach stay, Samui has the edge; to branch out to several Andaman islands, Phuket is more central.
What's the best time to visit Koh Samui?
From January to September, with a peak of good weather from February to July. Unlike the Andaman coast, Koh Samui stays practicable most of the year; mainly avoid October-November, the rainiest period in the Gulf of Thailand.
Should you rent a scooter in Koh Samui?
It's the most practical way to explore the island (roughly 50km ring road), but tourist accident rates are high: prioritise a helmet, careful riding and insurance that covers two-wheelers. Without a scooter, songthaews (shared taxis) serve the main beaches well.
