Free Things to Do in Koh Samui

Some of the best things to do in Koh Samui cost nothing at all. The island's temples, viewpoints, night markets, waterfalls and beaches are free to enjoy, and with a little planning you can fill several days without spending more than the cost of a meal and a ride.

Quick answer: The best free things to do in Koh Samui are visiting the Big Buddha and Wat Plai Laem, seeing Hin Ta and Hin Yai rocks in Lamai, walking up to Na Muang 1 waterfall, browsing the Fisherman's Village Night Market in Bophut (Monday, Wednesday, Friday and Sunday), watching the sunset from the west coast, and swimming at public beaches such as Silver Beach and Choeng Mon. Temples welcome donations, and a few spots charge a small fee.

Free temples and landmarks

Big Buddha (Wat Phra Yai)

The island's best-known landmark is a 12-metre golden Buddha on a small island joined to the shore at Bangrak. Entry is free, though donations are welcome. Climb the naga staircase for views across the bay, and cover your shoulders and knees.

Wat Plai Laem

A few minutes from the Big Buddha, this colourful temple has an 18-armed statue of Guanyin, the goddess of mercy, rising from a lake. It's free to visit and is one of the most photogenic spots on the island.

Wat Khunaram and the mummified monk

On the south side of the island, Wat Khunaram is home to the mummified body of a revered monk who died in meditation in the 1970s. He still sits upright in a glass case, famously wearing sunglasses. Entry is free.

Laem Sor Pagoda

This golden pagoda stands right on the shore in the quiet south-west of the island. There's no entrance fee, and the setting at sunset is lovely.

Hin Ta and Hin Yai

The Grandfather and Grandmother Rocks at the southern end of Lamai are natural rock formations with a local legend attached, and they're free to visit. Stalls nearby sell kalamae, a sticky coconut sweet that is a Samui speciality.

Free night markets

Fisherman's Village Night Market, Bophut: Monday, Wednesday, Friday and Sunday evenings, with street food, crafts, live music and old wooden shophouses. See our Bophut and Fisherman's Village guide.
Lamai Sunday Walking Street: a lively Sunday-evening market in the centre of Lamai.
Nathon Night Food Market: a local favourite on the seafront in the island's old town, with sunset views. See our Nathon guide.

Browsing is free, and a street-food dinner costs around 50 to 150 THB a dish.

Free waterfalls and viewpoints

Na Muang Waterfall

Na Muang 1 is a short walk from the car park and has a pool at the bottom, with no entry fee. Na Muang 2 is a steeper hike further up and may carry a small charge. The falls are fullest in the rainy season, from October to December, when paths are also more slippery.

Lad Koh Viewpoint

On the coast road between Chaweng and Lamai, this roadside viewpoint looks out over the rocky coastline and the sea. It's free and makes an easy stop on the way between beaches.

Hiking trails

The island's jungle interior has trails to waterfalls and viewpoints. Our guide to hiking in Koh Samui covers the best routes, how hard they are and what to bring.

Free beaches and sunsets

All beaches in Thailand are public, so you can swim and sunbathe anywhere, even in front of a resort. A few favourites:

Silver Beach (Crystal Bay): a small, pretty bay between Chaweng and Lamai with clear water.
Coral Cove: a rocky cove with reef fish close to shore; bring your own snorkel.
Choeng Mon: a calm, family-friendly bay with views of Koh Fan Noi. See our Choeng Mon guide.
West coast sunsets: Nathon and Lipa Noi face west over the sea towards the mainland and Ang Thong Marine Park, so they get the island's best sunsets.

Almost free

Secret Buddha Garden: a hillside sculpture garden high in the interior, with an entrance fee of around 80 THB. The road is steep, so many people visit on a private cultural tour.
Local festivals: if your trip coincides with Loy Krathong in November or Songkran in April, the celebrations are free to join.

Tips for a low-cost day

Visit temples early in the morning or late in the afternoon, when it's cooler and quieter.
Carry water, sun cream and a cover-up for temples.
Combine nearby stops: the Big Buddha and Wat Plai Laem, or Hin Ta and Hin Yai with Wat Khunaram.
Use a songthaew or Grab between sights; see our guide to getting around Koh Samui.
