Khao Phra Thaeo Wildlife Sanctuary is home to the most pristine tropical rainforest on Phuket Island and is considered the province's most important terrestrial conservation area. Covering approximately 22–23 square kilometers, or about 13,000–14,000 rai (approximately 2.9 hectares), it's located in the central-northeastern part of the island, with its highest peak reaching approximately 442 meters above sea level. This area was declared a protected zone in 1969 to preserve the rainforest ecosystem that once covered Phuket Island before rapid urban development and tourism expansion.

A distinctive feature of this forest is its complex multi-layered structure, comprising large trees with buttress roots, numerous vines and climbing plants, and important endemic species such as the White-backed Palm, a rare plant first discovered in this area and found in very limited locations in Thailand. The biodiversity reflects the richness of the intact tropical rainforest ecosystem, including undergrowth, ferns, mosses, and epiphytes growing on large trees.

In terms of wildlife, the area is home to a diverse range of animal species. Although some large animal species have disappeared over time, medium and small mammals such as gibbons, macaques, langurs, civets, porcupines, and slow lorises, as well as hoofed animals like barking deer and muntjacs, can still be found in the area. In addition, there are over 80 bird species, including the Great Hornbill, Broadbill, and Oriental Pied Hornbill, making the area ideal for birdwatching and nature studies. Reptiles are also diverse, including pythons, venomous snakes, and tortoises, most of which inhabit deeper areas and are not easily seen along tourist trails.

Within the sanctuary, important natural attractions include "Ton Sai Waterfall" and "Bang Pae Waterfall," which serve as starting points for nature trails. Ton Sai Waterfall is located near the park office and is ideal for easy access and relaxation, while Bang Pae Waterfall is taller and home to a highly diverse humid gibbon rehabilitation project. The hike to Bang Pae Waterfall takes several hours and is suitable for experienced hikers or those with a guide for safety.

Beyond its role in ecotourism, Khao Phra Thaeo serves as a vital watershed for Phuket, helping to conserve water and maintain the island's ecosystem balance. The area is also used as a center for nature studies and environmental research because it retains a near-original forest environment of Phuket's past. Conservation of this area is therefore crucial for both biodiversity and the long-term sustainability of natural resources.
