The 2020 Koh Samui events calendar is ready for anyone clever enough to plan things in advance (and always here for those of us who show up and hope for the best).
Are you more of a last-minute sort? You’re in luck – Koh Samui is often a last-minute kind of place. Below, you’ll find annual Koh Samui events, holidays, festivals and 2020 Full Moon Party dates (on nearby Koh Phangan). I update this calendar regularly as new or last-minute events are announced. Enjoy!
