The 71,187-hectare Cat Tien National Park, one of 11 UNESCO-recognized biosphere reserves in Vietnam, has incredible biodiversity, such as deer, civet, leopard cat, and a number of primates, including over 500 yellow-cheeked black gibbons. The early morning trek to hear their beautiful synchronized singing is one of the park's highlights.
The access point is a short ferry from Nam Cat Tien across the Dong Nai River to the park headquarters. Activities inside are managed by the national park itself, except for the half-day tour of the moon and sun bear sanctuary, which is booked through Free the Bears. The park offers a jungle trek and overnight camping at a lake full of endangered Siamese crocodiles, a night safari (by vehicle on roads), and bird watching. It is easiest to book park tours through your guesthouse. The do-it-yourself option is to rent bicycles from the park office. There are sights within 15 km (9.3 miles), such as the Ben Cu rapids and notable ancient trees; go as early as possible to avoid the midday heat. The headquarters also has a small wildlife rescue center and nature museum with preserved specimens.
The national park's hotel, located within the park next to the boat landing, has different room blocks and bungalows of varying quality, from 350,000d to 800,000d per night. The latest bungalows added in 2024 have modern amenities including air-conditioning and en suite bathrooms. Camping costs 100,000d per person, with tent rental available. There is cleaner, more comfortable accommodation in the village, but staying inside the park means hearing the gibbons singing in the morning, and it is convenient for early morning treks and the night safaris. Note that the last public boat is around 6:30 pm, meaning dinner must be taken at the park hotel's restaurant.
