Na Thon Beach
Samui's forgotten west-coast strip, wild and unguarded
About
stretches roughly 800 metres along Koh Samui's quiet west coast, backed by rubber tree plantations that press right to the shoreline and cut the beach off from the rest of the island's tourist circuit. The sand is grey, giving the shore a raw, elemental look that feels nothing like the postcard beaches on the east side. Blue Gulf of Thailand water rolls in from the open horizon, and because the beach faces due west, the sky turns vivid at dusk with nothing blocking the view. There is zero tourist infrastructure here — no sunbeds, no vendors, no signage — just an unmarked dirt track, the tree line, and the sea. It's the kind of place that feels genuinely off the map.
How to get there
The beach is reached on foot from Na Thon town via an unmarked dirt track — allow around 20 minutes each way. There is no formal parking; motorbike riders leave their bikes at the track entrance. No entry fee exists, but the track can flood during heavy monsoon rain and mobile signal drops out in sections, so go prepared.
Who it's for
For couples
If you and your partner want a sunset with no one else around, this is one of the few places on Samui that genuinely delivers solitude — just pack a picnic and keep well clear of the water.
For families
Not recommended for families with young children: access is a 20-minute hike on an unmarked dirt track, there are no facilities whatsoever, and swimming is dangerous. Lipa Noi Beach, 6 km away, is a far safer and more comfortable family option.
Our take
Feet in the sand, eyes on the screen
Do not come here expecting a beach day in the conventional sense. Swimming is dangerous, there is not a single facility, and the access track is unmarked and flood-prone in the wet season. What does offer is something genuinely rare on Koh Samui: 800 metres of grey-sand west-coast shoreline with a rubber plantation at your back, blue open water ahead, and nobody else around. The sunset exposure is real and unobstructed. Come in the dry season — November through April — hike the 20 minutes from Na Thon, stay for the light, and leave before dark. Skip it entirely from May to October.
What to do
Nathon Town, Samui's administrative capital, sits about 2 km away and is worth a short wander for its local market and ferry terminal atmosphere. Lipa Noi Beach, 6 km south, is the island's go-to sunset spot with views across to Ko Pha-ngan if you want a beach where you can actually swim. For something more adventurous, Ang Thong Marine National Park — an archipelago of 42 islands — is accessible by day-trip boat from around 28 km away.
The grey sand at low tide with the blue Gulf stretching to the horizon makes a stark, moody wide-angle frame that looks nothing like typical Samui shots.
The rubber tree plantation meeting the beach edge is a strong compositional detail — shoot back from the waterline toward the tree line in the golden hour before sunset.
Where to eat
Just 0.3 km from the track entrance, Krua Savoiey Seafood and Lucky Restaurant both offer straightforward meals close to the beach. See Faa Cafe is at the same distance if you want something lighter. A short walk further brings you to Ristorante Pizzeria Nettuno (0.4 km) and Ban Somtum (0.5 km) for Thai classics.
Where to stay
Grand Sea View Beach Resotel is the closest option at 0.2 km, putting you within easy walking distance of the track. Jinta Hotel and Jinta City Hotel are both under 0.5 km away, with Win Hotel and Sri Samui rounding out the nearby choices at 0.5 km.
Photography
The best shot is at sunset from the waterline, with the grey sand in the foreground and the open blue Gulf horizon catching the last light — arrive 30 minutes before sundown. The rubber tree plantation edge also makes a strong frame for wide shots that show just how isolated this strip really is.
Good to know
Bring all the water and food you need — there are absolutely no facilities on the beach. Swimming is dangerous: southwest swell makes entering the water hazardous from May through October, and conditions can look deceptively calm before they turn. Even outside monsoon season, treat the water with caution and do not swim alone. If you're visiting during or after heavy rain, the dirt track may be impassable.
