Nahai Beach

About 2 km of shallow, waveless beach between Lamai and Hua Thanon. Spectacular low tides expose a huge mirror-flat sand flat. Popular with kitesurfers; too shallow for real swimming but great for children paddling and photos.

Insider tips

  1. Check a tide table: the low-tide mirror flat is the whole point of this beach.
  2. Bring shade, water and sun protection - there is little natural shade and almost no services.
  3. Good spot to watch or try kitesurfing in the windy season.
  4. Combine with the Hua Thanon morning fish market nearby.

The story

Nahai Beach runs for just over 2 kilometres along the southeast coast, from the old pier of Hua Thanon village toward Lamai. It is one of the shallowest beaches on the island: at high tide the water reaches the edge of the sand, but at low tide it retreats 150-170 metres and exposes an enormous flat of firm, fine, almost white sand - locals even drive pickups across it. In calm weather the wet flat becomes a giant mirror, which is why photographers like it, and the shallow water stretching far out is safe for young children to play in (with supervision).

Real swimming is not practical - it is wading depth for a long way. The beach is a known kitesurfing spot, and there are no beach vendors, sunbed rentals or bars outside the few hotels, so it stays quiet. The downside: there is little natural shade, some rocks in the water, and the area near the Hua Thanon fishing village is cluttered with boats and gear and can be untidy.

Reach it via the side roads off the ring road between Lamai and Hua Thanon; a scooter or taxi is the practical option.
