Hin Phoeng Rapids in Prachinburi Province is one of the most famous whitewater rafting spots in Thailand. Located in Na Di District, within the responsibility of Khao Yai National Park Unit 9 (Sai Yai), the rapids are formed by the Sai Yai River flowing through massive rock formations before joining the Nakhon Nayok River and later the Bang Pakong River.

 

During the rainy season, from July to November, the Sai Yai River swells with water, creating powerful currents and cascades that make Hin Phoeng Rapids an ideal destination for whitewater rafting. With a difficulty rating between Class III and V, the rapids provide an adventurous experience that combines thrilling challenges with the scenic beauty of lush forest landscapes in Khao Yai National Park.

 

The rafting route covers a distance of about 4–5 kilometers. Visitors are usually guided on a 2.5-kilometer forest trek, taking about 45 minutes to reach the starting point. The rafting adventure then passes through several significant rapids, including the main Hin Phoeng Rapids, Wang Nam Lom, Wang Bon, Luk Suea, Wang Sai, and Ngu Hao. The rafting trip lasts around 20–30 minutes depending on the water conditions.

 

The challenge of rafting here lies in the swift currents crashing against boulders, creating whirlpools and waves that require teamwork to navigate safely. Experienced rafting guides lead the groups, ensuring synchronized paddling to avoid capsizing. This combination of excitement, teamwork, and natural beauty makes Hin Phoeng Rapids a must-visit adventure in Thailand.

 

Safety is a top priority. All participants are provided with life jackets, helmets, and ropes, while trained staff are stationed at every point along the route to handle emergencies. Visitors can therefore enjoy rafting with confidence, provided they follow safety instructions carefully.

In 2025, the 26th edition of the festival will be held from August 9–12 at Khao Yai National Park Unit 9, featuring official opening ceremonies, conservation activities, and full rafting experiences that attract both Thai and international tourists.

The fee usually includes safety equipment, guides, and transportation between the starting and ending points.
