Things to do in Koh Samui
Koh Samui is Thailand's second-largest island, offering stunning beaches, lush jungle, and vibrant nightlife at a fraction of what you'd pay in the Maldives or Bali. With a mix of cheap street food, free temple visits, and affordable island-hopping, it delivers serious tropical luxury on a budget.
Why go to Koh Samui
Big Buddha Temple (Wat Phra Yai)
A golden 12-meter seated Buddha rises above the northern shoreline-utterly iconic and completely free to visit.
Ang Thong National Marine Park
A jaw-dropping archipelago of 42 limestone islands with emerald lagoons, sea caves, and snorkeling reachable by day tour.
Chaweng Beach
The island's liveliest stretch of white sand with turquoise water, beach bars, and buzzing nightlife all in one place.
Grandfather and Grandmother Rocks (Hin Ta Hin Yai)
Bizarre and beloved coastal rock formations that are free to see and endlessly entertaining for the whole group.
Namuang Waterfall
Twin jungle waterfalls deep in the island's interior where you can swim in natural pools-raw, beautiful, and barely touristy.

Good to know in Koh Samui
- Transit: Songthaews (shared red pickup trucks) are the cheapest way to get around at $1-2 per ride; agree on the price before you get in. Renting a scooter for $8-10/day gives you full freedom but drive cautiously-roads can be steep and wet.
- Tipping: Not culturally mandatory but appreciated; rounding up the bill or leaving $0.50-1 at restaurants is generous and welcomed.
- Tap water: Do NOT drink tap water in Koh Samui-the infrastructure is unreliable. Buy large refill water bottles at 7-Eleven for under $0.50 or use refill stations.
- Free entry: Most temples including Big Buddha and Wat Plai Laem are free every day; Ang Thong Marine Park charges a ~$3 national park fee on top of tour costs, but there are no special free-entry days for parks.
