White sand of Bang Kao Beach on the south coast of Koh Samui

Bang Kao Beach

A long, wild, undeveloped beach on the south coast - 3.5 to 5 km of palms and empty sand with almost no facilities. Too shallow and stony for swimming, but the most 'old Samui' shoreline left. Bring everything you need.

Insider tips

  1. Bring absolutely everything - water, snacks, sun protection. There are essentially no facilities.
  2. Do not come for a swim; come for the wild scenery, wading and the pagoda.
  3. Combine with Laem Sor Pagoda, Laem Set and Thong Krut on one south-coast day.
  4. Kitesurfers and paddleboarders use this coast in season thanks to the shallow flat water.
  5. Keep distance from stray dogs reported in the area.

The story

Bang Kao is the long beach of the undeveloped south coast, held between Laem Set cape in the east and Laem Sor cape in the west. 5 km to about 5 km. This is Samui as it was before tourism: a wide sweep of fine sand backed by coconut palms, with no beach clubs, no sunbed rows and almost no services of any kind.

The trade-off is swimming: the water is extremely shallow for a long way out and the bottom is stony and muddy in places, so several guides call it unsuitable for swimming; at low tide you may walk hundreds of metres before the water reaches your waist. On the plus side the water is calm and clear, so wading and watching small sea life in the shallows can be enjoyable. There are views across to the islands of Koh Taen and Koh Madsum.

At the western end stands the golden Laem Sor Pagoda right at the waterline - a working fishermen's temple, free to visit. Practical warnings: bring all water, food and sun protection; stray dogs are reported in the area; there is no public transport - come by scooter, car or taxi as part of a south-coast loop.
