Khao Khiao–Khao Chomphu Wildlife Sanctuary

Khao Khiao–Khao Chomphu Wildlife Sanctuary, located in Chonburi Province, eastern Thailand, covers a mountainous region characterized by tropical and evergreen forest ecosystems. The sanctuary spans rolling hills and ridges of the Khao Khiao range, rising to elevations that support diverse flora and fauna uncommon in the surrounding lowlands. Established in 1974, it was created to protect the remaining wildlife habitat and serves as an important refuge for native species such as gaur (Indian bison), banteng, various deer species, and numerous bird species. The sanctuary’s dense forests include dipterocarp trees and bamboo groves, which support a complex ecological community.

Outdoor opportunities here focus on wildlife viewing, birdwatching, and hiking. Several trails cut through the forest, allowing visitors to explore the area's serene environment. The proximity of the Khao Khiao Open Zoo, which borders the sanctuary, adds an educational element to visits, highlighting regional conservation efforts. Visitors can observe endemic species in the wild, benefiting from the sanctuary’s relatively undisturbed habitat. The area appeals to adventurers looking for peaceful trekking routes away from the busier national parks in Thailand, and photographers who want to capture the scenic forest landscapes and its inhabitants. Its accessibility from the city of Chonburi provides opportunities for day trips or short ecological excursions.
