Tonsai Bay, Railay
Ao Ton Sai lies immediately north of Railay West, separated from it by a headland that can be walked around at low tide and not at high. It is the climbing bay: cheaper, scruffier and more committed than Railay, with bungalows back among the trees rather than on the sand.
The walls above it hold some of the hardest sport routes in Thailand, and the bay's culture is built around them - gear shops, climbing schools and bars where the day is talked through afterwards. The beach itself is rocky and shallow and is not the reason anyone stays.
Longtails run from Ao Nang. Electricity in the bay has historically been limited to certain hours at some places, so check if that matters to you.
