Kaeng Krachan National Park Guide: Explore Thailand’s Largest Natural Reserve

Kaeng Krachan is Thailand’s largest national park, stretching across the provinces of Phetchaburi and Prachuap Khiri Khan. Recognized as a UNESCO World Heritage Site in 2021, this vast natural reserve is a haven for nature lovers and wildlife enthusiasts.

Kaeng Krachan National Park is a true sanctuary for wildlife and biodiversity. With its forested mountains, rivers, and valleys, it is a top destination for hiking, birdwatching, and observing wildlife in its natural habitat. This is not a commercialized elephant bathing site, but a genuine ecosystem where animals live freely, far from the postcard-style promises of fake conservation sanctuaries.

Kaeng Krachan National Park: A Biodiversity Hotspot

Established in 1981, Kaeng Krachan covers 2,915 km², making it the largest national park in Thailand. Its rich biodiversity has earned it the nickname “Thailand’s green lung.”

Mammals

The park is home to an impressive range of mammals, including leopards, Asiatic black bears, elephants, gaurs, dholes, and serows. Although tigers are rare, a few individuals have recently been captured on camera traps.

Birds

Kaeng Krachan is one of the best birding spots in Thailand with around 480 species recorded. It is the only place in the country to spot the ratchet-tailed treepie and hosts several species of hornbills and broadbills.

Reptiles

With over 120 species of reptiles—70 of them snakes—the park is a fascinating ecosystem. Visitors might encounter three types of pit vipers, king cobras, and rare species like Brongersma’s short-tailed python.

Butterflies

Kaeng Krachan also attracts butterfly watchers with nearly 300 species fluttering through the forest.

Park News

Three Bengal Tiger Cubs Spotted

In a rare and exciting update from Kaeng Krachan National Park, three Bengal tiger cubs have been recorded on camera traps. Previously, only one cub was seen with its mother in late 2024. In February 2025, new footage confirmed the presence of three healthy cubs, roughly six months old. Their mother is seen keeping a watchful eye as the cubs play in the underbrush.

There are currently six adult Bengal tigers in the park—two males and two females among them. While tiger sightings remain rare, this discovery marks a hopeful milestone in conservation efforts. The slight population increase in Thailand echoes similar trends seen in India and Nepal.
