Koh Tao beaches / Sai Nuan Beach
A small, sheltered beach just south of Mae Haad, reached by a steep road or a pleasant coastal walk.
Sai Nuan Koh Tao is one of the island's easiest beaches to like. It sits on the west coast a short way south of Mae Haad, tucked behind rocks and banana trees, with soft pale sand and calm water on most days. There are no tour boats and no big resorts, so it stays quiet even in high season.
Most people arrive on a scooter, but the best way in is on foot. A concrete coastal path links Mae Haad, Sai Nuan and Jansom Bay, and the walk is half the fun. Come late afternoon, swim, then stay for sunset.



Sai Nuan is really a pair of small beaches a few minutes apart. The sand is soft and pale with a little crushed coral in it, and the water is shallow and easy to enter. When the wind comes from the east it is very calm. A strong westerly can bring some chop, and on those days you may prefer Aow Leuk or Tanote Bay.
The first section has a grassy area and is the more developed one, and some visitors report a small fee to use it. The second beach is free and has a couple of shaded cafes plus Banana Rock Bar, a thatched bar built into the rocks. At high tide you may need to wade a little to reach the bar, so bring a dry bag if you carry electronics.
You have two good options, and neither needs a boat.
A third route links Sai Nuan with the next bay north. A sandy path beside Banana Rock Bar runs through banana trees to Sai Thong Beach, then on to Jansom Bay. Expect 20 to 30 minutes at an easy pace. Jansom Bay is private and charges an entrance fee, though you can often walk across the sand without stopping. Check at the gate.
The reef directly in front of the beach is a bit worn near the shore, but it improves as you swim out and there are boulders worth a look. Heading north towards Sai Thong tends to be the most rewarding swim, with reef fish and the occasional turtle or small reef shark. South towards the headland the coral is healthier but the water is deeper.
Go at higher tide if you can, since the shallows are easiest to swim then. Bring your own mask and fins, and avoid standing on coral. For more places to get in the water, see snorkelling on Koh Tao.
Facilities are simple: small local restaurants, a bar with toilets, and a few spots along the access road for a beer or coffee. This is not the place for sunbeds and watersports. It is a good place to sit on the rocks with a drink and watch the sun drop behind the Gulf.
Plan your return before dark. The road is steep and has little lighting, and the coastal path is easier with a phone torch. If you want a full evening out afterwards, Mae Haad is close, and our restaurant guide and bar guide have more ideas.

By scooter or taxi down a short, steep, sealed road south of Mae Haad, or on foot along the signed coastal path from Mae Haad in about 30 minutes.
The main beach and the road in are generally free. Reports vary for the first, more developed section, and neighbouring Jansom Bay charges an entrance fee, so carry a little cash.
It is fine rather than outstanding. The reef near the shore is worn, but it improves farther out and towards Sai Thong, where turtles are sometimes seen.
Yes. It faces west, and Banana Rock Bar and the rocks nearby are popular for sunset drinks. Leave in good time because the road is steep and dark.
Yes. It takes about 30 minutes on a concrete coastal path with signs, and you can carry on to Sai Thong and Jansom Bay.
It is usually sheltered and shallow, but a strong west wind can make it choppy. Check conditions, and swim only where you are comfortable.
