Fodor's Expert Review Cat Tien National Park

The 72,000-hectare ruggedly beautiful Cat Tien National Park, one of nine biosphere reserves recognized by UNESCO in Vietnam, is home to hundreds of species of plants, birds, animals, and reptiles, including several species of endangered monkeys, Asian elephants, sun bears, and gaur. (Sadly, Vietnam's last Javan rhino was shot in the park by poachers in 2010.) The national park office has cars, bicycles, and boats available for hire and guests staying at the national park's hotel can book early-morning gibbon treks for 1,050,000d per person. The price includes breakfast at one of the two restaurants inside the park and a tour of the gibbon rehabilitation center. Accommodation within the park is basic, with small double rooms starting at 350,000d. There are nicer accommodation options outside the park, which can also arrange jungle excursions for you.
