Khao Ang Rue Nai Wildlife Preserve Area, Chachoengsao

Khao Ang Rue Nai Wildlife Preserve offers one of central Thailand’s most accessible wilderness experiences, just two hours from Bangkok in Chachoengsao province. This compact but diverse protected area combines limestone hills, dense forest, and grasslands in a landscape that feels worlds away from the urban sprawl. Unlike Thailand’s more famous national parks, this preserve maintains an authentic, low-key atmosphere where serious wildlife enthusiasts can explore relatively undisturbed habitats without fighting crowds for the perfect photo spot.

Wildlife watching takes center stage here, with several well-maintained trails winding through different ecosystems. Early morning hikes often reward visitors with sightings of sambar deer, wild boar, and various monkey species moving through the forest canopy. Birdwatchers particularly appreciate the diverse avian population, including hornbills, kingfishers, and numerous endemic species that call out from the trees. The park’s limestone formations create interesting cave systems and rocky outcrops that add geological intrigue to nature walks. During the cooler months, butterflies dance through clearings while the air carries the earthy scent of decomposing leaves and blooming forest flowers.

Peace defines the experience at Khao Ang Rue Nai, where the only sounds are rustling leaves, bird calls, and your own footsteps on forest paths. This tranquil environment appeals to visitors seeking genuine connection with nature rather than Instagram opportunities. Rangers maintain the trails well but keep facilities minimal, preserving the preserve’s wild character. The smaller scale creates an intimate feeling – you’re exploring nature rather than touring through it.

Visit between November and February for the most comfortable hiking weather and increased wildlife activity. Basic camping facilities are available for those wanting to experience dawn and dusk wildlife movements. Bring insect repellent, plenty of water, and sturdy hiking shoes for the sometimes steep terrain. Foreign visitors pay 200 baht entry (100 baht for children), considerably more than Thai nationals. The preserve closes at 4 PM, so plan accordingly for your wildlife watching and hiking activities.
