Top 10 Things To Do in Koh Samui
We've lived on Koh Samui for years — these are the experiences we recommend to every visitor, from first-timers to repeat travellers.
42 uninhabited limestone islands, emerald lagoons, kayaking and the best snorkeling in the Gulf. The inspiration for "The Beach" — the island's unmissable experience. Day tour only, book via Klook.
Koh Samui's longest and most vibrant beach — 7km of white sand backed by coconut palms. Best at golden hour when the light turns everything amber. Free.
30,000 people, fire shows, and the world's most famous beach party — every month on the full moon at Haad Rin Beach. Ferry from Samui takes 30 minutes.
The best snorkeling and diving in the Gulf — whale sharks, sea turtles and spectacular coral at Koh Nang Yuan. 2 hours by speedboat from Samui.
Wat Phra Yai's 12-metre golden Buddha and Wat Plai Laem's 18-armed Guanyin — two of Thailand's most spectacular temple complexes, both free to visit.
Cocktails, Thai canapes and the most spectacular sunset in the Gulf — the west coast catamaran cruise is one of Koh Samui's most romantic experiences.
Learn to cook pad thai, massaman curry and mango sticky rice with local chefs — the most popular activity on the island for couples and food lovers.
Koh Samui's second beach has better waves than Chaweng — perfect for beginner surfing and bodyboarding October-December when the northeast swell arrives.
Quad biking through Koh Samui's jungle interior and zip-lining over the rainforest canopy — the most adrenaline-packed half-day on the island.
Friday Night Walking Street in Bophut — local street food, live music, craft stalls and the island's most charming village atmosphere. Every Friday 5-10pm. Free.

Visit Koh Samui — FAQ
The top things to do in Koh Samui are: visiting Ang Thong National Marine Park on a day tour (the island's unmissable experience), island hopping to Koh Phangan and Koh Tao, relaxing on Chaweng or Lamai Beach, visiting the Big Buddha and Wat Plai Laem temples, taking a Thai cooking class and watching the sunset from the west coast. For nightlife, Bophut Fisherman's Village on Fridays is the most authentic experience on the island.
We recommend a minimum of 5-7 days in Koh Samui to do the island justice. Day 1-2 for beaches and settling in, Day 3 for Ang Thong Marine Park, Day 4 for a trip to Koh Phangan, Day 5 for the island interior and temples. If you want to add Koh Tao for diving, allow 7-10 days total. Longer stays of 2-4 weeks are increasingly popular with digital nomads on the DTV visa.
Yes — Koh Samui is excellent for families. Choeng Mon and Maenam beaches have calm, shallow water perfect for young children. The Big Buddha and temple tours are educational and engaging for kids. Several ethical elephant sanctuaries operate on the island. For accommodation, the Ritz-Carlton and Anantara Bophut have dedicated kids clubs and family programmes.
January to April is the best time to visit Koh Samui — dry season, calm seas and the best conditions for island hopping and beach activities. December is peak season with higher prices. May-June offers good weather and lower prices — our best value recommendation. Avoid October-November on the east coast due to monsoon, but the west coast (Conrad, Nikki Beach) stays sunny year-round.
