These twin islands south of Phuket offer rather different experiences. The good facilities, white beaches, mountain top viewpoint and surrounding corals, in Ko Racha Yai guarantee a convenient and enjoyable visit. Skilled divers, on the other hand, will enjoy the deep sea, strong currents, abundant fish, and beautiful beaches in the atoll Ko Racha Noi. The latter is not good for swimming.
The currency used in Thailand is the Baht.
