Plaisang and Khlong Saeng Sanctuaries are two of Thailand’s most secluded and biologically rich conservation areas. Located deep within Surat Thani province, these sanctuaries are often overlooked in favor of popular destinations like Cheow Lan Lake or Khao Sok National Park. Yet for those seeking raw wilderness, rare wildlife, and meaningful eco travel experiences, this hidden duo is nothing short of extraordinary.
These sanctuaries form a vital ecological corridor within the Western Forest Complex, making them crucial to the survival of endangered species. In this blog, we explore what makes Plaisang and Khlong Saeng Sanctuaries a must-visit for nature enthusiasts and why they should be at the top of your off the beaten path itinerary in southern Thailand.

1. Untouched Rainforest Ecosystems
Plaisang and Khlong Saeng Sanctuaries remain largely undeveloped and protected from mass tourism. Their remoteness is their charm. Unlike national parks with designated trails and visitor centers, these sanctuaries are research driven and require permits for entry. The lush forests are alive with natural rhythms bird calls, rustling leaves, and animal tracks on muddy trails. These environments support cloud forest conditions, dense evergreen canopies, and seasonal rivers that provide habitat for dozens of threatened species.
2. Exceptional Wildlife Viewing Opportunities
This area is one of the last strongholds for large mammals in Thailand. With the help of trained guides or wildlife researchers, lucky visitors might spot:
- Malayan tapir
- Gaur (Indian bison)
- Asian elephants
- Leopard cats and clouded leopards
- Hornbills, eagles, and other rare birds
These species thrive in the isolation and protection offered by Plaisang and Khlong Saeng Sanctuaries. The sanctuaries are also used for camera trap studies and biodiversity monitoring projects, making it a hotspot for conservation based tourism.
3. Adventure with Purpose
Visiting Plaisang and Khlong Saeng Sanctuaries is not like joining a casual tour. Most trips here involve staying in ranger stations, trekking with forest officials, and boating through remote waterways. Some eco operators based in Khao Sok offer wildlife tracking expeditions and photography trips that support local conservation efforts.
This kind of adventure gives travelers a chance to learn about wildlife conservation firsthand. By participating, you contribute directly to the protection of these habitats supporting ranger patrols, anti-poaching operations, and wildlife monitoring.
4. Conservation and Community Benefit
One of the most valuable aspects of these sanctuaries is their connection to conservation programs and nearby communities. Rangers, researchers, and local volunteers work together to protect endangered species, prevent illegal logging, and build awareness about biodiversity. When travelers join approved ecotours, the income often helps fund these initiatives.
Additionally, local communities around Plaisang and Khlong Saeng Sanctuaries are slowly developing low impact tourism options offering homestays, guided hikes, and community forest walks. These efforts allow visitors to experience authentic rural life while minimizing environmental footprints
5. Nearby Wonders to Explore
If you’re already in the region visiting Cheow Lan Lake or Khao Sok National Park, adding a day trip or overnight eco expedition to these sanctuaries is a great extension. The vast Khlong Saeng River flows through the sanctuary and eventually into the lake, creating a breathtaking mosaic of jungle and water. Morning mist over the lake’s limestone peaks is nothing short of magical, and exploring the wilder sides of the region will deepen your understanding of its ecological value.
Best Time to Visit
The ideal time to visit is during the dry season (December to April). Trails are more accessible, and animals tend to gather near water sources, making sightings more likely. Be sure to work with licensed eco tour operators and secure permits in advance especially for access to restricted core zones within Plaisang and Khlong Saeng Sanctuaries.
