Nha Trang is one of the most important tourist hubs of Vietnam, thanks to its beautiful beaches with fine and clean sand and the clear ocean water with mild temperatures all year round. There are several resorts - such as Vinpearl, Diamond Bay and Ana Mandara - and amusement and water parks, both in the city and on islands off the coast. The possibly most beautiful street of Nha Trang is Tran Phu Street along the seaside, sometimes referred to as the Pacific Coast Highway of Vietnam.
Lying off Nha Trang is the Hon Tre Island (Bamboo Island), with a major resort operated by the Vinpearl Group. A motorized chair lift system, reportedly the longest in the world, links the mainland to the five-star resort and theme park on Hon Tre Island.
Nha Trang is a stopover for annual yacht races starting in Hong Kong. In recent years, the city has welcomed many five-star sea cruises. In addition to sail boat racing, Nha Trang provides a rich variety of tourist activities for visitors. Island hopping, scuba diving, water sports and other sporting activities can be enjoyed in the city. The Nha Trang Tourist Information Center (a non-governmental organisation), located near the Cho Dam Market has been set up to provide information for visitors
The local cuisine is most famous for fresh seafoods and barbecued pork rolled in rice paper. The area's Bird's nest soup is deemed one of the best in Vietnam. Bird’s nests are collected in the wild, on bird farms on the islands off the coast and even in some houses in the inner city. The farmed bird in question belongs to the swiftlet group, popularly referred to as y?n hàng (Aerodramus fuciphagus germani).
