Khlong Saeng River Basin Conservation Area

Plaisang is located within the vast Khlong Saeng Wildlife Sanctuary, which was officially designated as a protected area in 1974. Covering extensive parts of Surat Thani Province, including Tambon Takuk Nuea, Vibhavadi District, Tambon Khao Phang, and Tambon Kraisorn, the sanctuary spans approximately 772,500 rai. In 1983, a portion of 49,875 rai was reshaped due to the construction of Ratchaprapha Dam, leading to the formation of the iconic Cheow Lan Lake. The name “Cheow Lan” originates from one of the rapids in Khlong Saeng, with its winding canal serving as a natural boundary between Khlong Saeng Wildlife Sanctuary and Khao Sok National Park.

Flora and Fauna of Plaisang:

Plaisang, along with Khlong Saeng, was once part of an extensive evergreen forest. Situated within the Tenasserim mountain range, this region boasts one of southern Thailand’s richest ecosystems. The landscape features a mix of forested hills and lowland plains, interwoven with crystal-clear streams that sustain a diverse range of plant species. This thriving tropical environment serves as a sanctuary for countless species of flora and fauna, including rare and endemic wildlife found nowhere else in the world.


Rivers and Natural Waterways:

Plaisang is renowned for its pristine streams and natural headwaters that originate from the dense rainforest. These clear, flowing waters carve their way through the limestone cliffs, providing a crucial water source for wildlife, especially during the dry season. The streams not only sustain the ecosystem but also create a habitat for freshwater fish and other aquatic life, offering visitors a glimpse into the region’s thriving biodiversity.


Biodiversity and Wildlife Conservation:

Plaisang and Khlong Saeng are teeming with diverse wildlife, supported by the sanctuary’s rich and varied habitats. Majestic animals such as wild elephants, gaur, serow, and wild boars roam freely through the forests, while vibrant bird species like hornbills and eagles dominate the skies. The area also serves as a refuge for rare and endangered species, making it an essential hub for conservation. The best wildlife viewing opportunities occur in the early morning and late afternoon when animals gather near streams and watering holes.


How to Get to Plaisang:

Reaching Plaisang begins with a scenic longtail boat journey from Cheow Lan Pier, taking approximately 1-2 hours. The ride offers breathtaking views of Cheow Lan Lake, with its towering limestone cliffs reflecting in the emerald waters. Upon arrival, visitors can embark on guided nature walks through the lush rainforest, providing a chance to observe wildlife and learn about the area’s rich biodiversity. Whether hiking along forest trails or spotting animals near the crystal-clear streams, Plaisang offers a truly immersive nature experience.


The Importance of Khlong Saeng’s Ecosystem:

Khlong Saeng Wildlife Sanctuary is a vital ecological treasure, preserving one of Thailand’s most diverse natural habitats. Its vast lowland forests, winding streams, and limestone formations support an incredible variety of plant and animal species. As a protected area, it plays a crucial role in conserving the remnants of the Tenasserim Mountain range’s ancient evergreen forests. From rare wildlife to unique ecosystems, Khlong Saeng stands as a must-visit destination for nature lovers and conservation advocates alike.
