Chalong Bay or Ao Chalong is on the east coast of Phuket, about 12 kilometres south of the Phuket town. It is the island's largest bay and Phuket's principal boat anchorage. It is very picturesque but not suitable for swimming. Many boats span out from Chalong to nearby islands such as Coral Island, Racha island and more. A number of restaurants and local shops are on the road leading to the bay. Wat Chalong or Chalong Temple is also easy reach to.

Accommodation in Chalong now ranges from budget to 5 star hotels. Chalong is a very good spot to stay before going diving or out on the water. The tourists can buy scuba equipment at wholesale prices.
