Pang Sida National Park

About Pang Sida

Covering 844 km² at Sa Kaeo Province, Pang Sida was declared as a national park in 1982. The national park lies within Dong Phayayen-Khao Yai Forest Complex, a World Heritage Site declared by UNESCO, covering 5 protected areas from Khao Yai to Cambodian border. The other protected areas are; Khao Yai National Park, Thap Lan National Park, Ta Phraya National Park and Dong Yai Wildlife Sanctuary.

The park comprises lush jungle mountains with valleys, cliffs, grasslands and waterfalls. The fertile forests include moist evergreen forest, dry evergreen forest, deciduous dipterocarp, mixed deciduous forest, hill evergreen forest.

Pang Sida National Park is a popular destination for its waterfalls, butterflies and birds. Main attractions of the park are located 22 km north of Sa Kaew north from headquarters. There are two camping grounds, park accommodations for rent, trails and a few waterfalls along this road. There are also a good number of easy, moderate and challenging trails.


Over the years, Pang Sida National Park has suffered much from poaching, in one case 30 individuals armed with assault rifles were recorded. The main target for the poachers is Siamese Rosewood classified as vulnerable (VU) by the IUCN Red List, in China sold for ten thousands of USD per cubic meter.

As a reintroduction programme initiated by Royal Thai Forest Service and Crocodile Management Association in Thailand, 20 siamese crocodiles were released in the park 2005 and 2006. Siamese crocodiles are critically endangered (CR) species according to the IUCN Red List and the global population is estimated to be a few thousand. There is also a significant population of tigers in the national park, recent camera traps revealed increased numbers of tigers within the forest complex.

The park and Sa Kaeo Province jointly hold an annual three month long butterfly watching festival from May to July which is the best time for butterfly watching. Around 400 species of butterflies have been recorded in the park, probably the best numbers in any park in the country. Butterflies can be seen in few spots where they gather in hundreds/thousands on wet grounds nearby mineral rich puddles or near the water-streams during the winter and hot seasons.

The park is not possible to reach by public transportation options, can only be explored by your own car or with a guide.

Visiting Pang Sida National Park is mainly about wildlife watching, hiking and camping but also a nice place to visit some waterfalls. Mammal watching in Thailand's dense forests is not an easy task, interesting mammals can be seen only with a lot of effort and regular visits.

Google Maps and various sketch maps of the national park show the main road north from the headquarters extending much further north, into neighbouring Thap Lan National Park until Khon Buri, that is not the case. The road ends shortly after a parking area next to the viewpoint at km 25. It may however be possible to hike by foot after this point, the path may be blocked by overgrown vegetation further in.

Pang Sida Waterfall

Huai Nam Yen Campsite

Named after the nearby waterfall, this camping ground is located 18.5 km north of the headquarters next to Huai Nam Yen Ranger Station.

Namtok Pha Takien Waterfall

Accessible by a 2.4 km long trail from Pang Sida Waterfall. The stream is quite dry during the dry seasons and less water during the cold season, it is in one of the streams that feeds Pang Sida Waterfall. The trail continues another few km beyond the waterfall until a confluence of several streams, towards the end of this second trail it becomes a bit hard to follow the trail.

Waterfall "trail"

Huai Nam Yen Waterfall

Accessible by a nearly 2 km long circular trail from Huai Nam Yen Camp Site. The trail is easy to hike and takes one hour to complete. The trail splits and continues further in two directions from the waterfall for hikers who want to spend more time hiking, one continues a bit west and the other northwest crossing the main road, an alternative way to get back to the campsite. Please check the map for these routes.

Thap Sung Waterfall

Accessible by a 2 km long trail starting 21 km north from the headquarters and 2.4 km north from the 2nd campsite (Huai Nam Yen Campsite).

The trail to the waterfall continues another few km and splits to two directions leading to Tharn Pla Plueng Waterfall and Tham Khang Khao Waterfall. Unfortunately there are no clear signs to keep the hikers on the right track, the trail becomes very difficult to follow deeper in.

Thap Thewa Waterfall

This waterfall is located 14 km east from the headquarters, accessible by a 3 km trail near Chong Klam Bon Reservoir and Ranger Station.
