Phu Khieo Wildlife Reserve, Ubon Ratchathani

Wild elephants roam freely through Phu Khieo Wildlife Reserve, one of Thailand’s most pristine wilderness areas where untouched forest meets rugged mountain terrain. This protected sanctuary forms part of the larger Dong Phayayen-Khao Yai Forest Complex, creating a vital corridor for endangered species across northeastern Thailand. The reserve’s dense canopy and remote location make it a genuine refuge for wildlife, offering visitors rare glimpses of animals in their natural habitat.

Dense tropical forest covers rolling hills and steep valleys, creating a maze of hiking trails that wind through different elevations and ecosystems. Wildlife viewing opportunities abound, with chances to spot elephants, bears, deer, and over 200 bird species that call this forest home. Early morning walks reveal fresh animal tracks along muddy paths, while the sounds of gibbons calling echo through the trees. Rangers lead guided tours to prime wildlife viewing spots, sharing knowledge about animal behavior and forest ecology. Photography enthusiasts find excellent vantage points from elevated trails, capturing images of the expansive canopy stretching to distant mountains.

Deep tranquility permeates the reserve, broken only by natural forest sounds—rustling leaves, bird calls, and the occasional crack of branches as large mammals move through the underbrush. The experience feels genuinely wild and remote, far removed from tourist crowds and commercial development. Walking these trails creates a sense of connection with Thailand’s natural heritage, where conservation efforts protect ecosystems that have existed for centuries.

Cool season months from November to February provide the most comfortable hiking conditions and increased wildlife activity. The reserve lies approximately two hours by car from Chaiyaphum city, requiring a motorbike or hired transport for the final stretch on unpaved roads. Bring sturdy hiking boots, insect repellent, and binoculars for wildlife spotting. Water and snacks are essential as facilities within the reserve are limited. This authentic wilderness experience rewards those seeking Thailand’s wild side beyond typical tourist destinations.
