Ko Nang Yuan is a small island very close to Ko Tao. It is famous for its diving spots and its great snorkelling beach. Many day trippers come from the islands of Ko Tao, Ko Pha Ngan, and Ko Samui, as well as from Surat Thani on the Thai mainland. It is also possible to come here for a snorkelling day trip from Ko Samui.

Plastic bottles and cans are banned from the island. Buy water and other drinks in glass bottles in Ko Tao to avoid paying inflated prices on Ko Nang Yuan.
