Yalong Bay is a 7.5km beach located southeast of Sanya City.
In the last years Sanya developed to become a getaway from Hong Kong and a relaxing place for extending a holiday without a long trip back home. The first international Resort hotel was opened and managed by Swiss hotelier N.C. Solari in 1999, in Yalong Bay.

Nowadays, international hotel chains have established in what is becoming a world-known destination, especially following the Miss World beauty pageant in Crowne Plaza, a hotel along Yalong Bay. The resort in Sanya Bay, the Palm Beach Resort and Spa welcomed the first Miss China beauty pageant in modern times. The organizer Julia Morley was decided by Sanya to welcome the international pageant the following year. Sanya attracts many Russian tourists as can be seen by many Russian signs throughout the city. There is a butterfly museum and a shell aquarium.

Lu Hui Tou (Deer turns its head) A large stone statue above Sanya harbour telling the story of a hunter pursuing a deer to an isolated headland in the sea.
