Huai Phai Waterfall is regarded as one of the most spectacular and largest waterfalls within Phu Ruea National Park. Originating from a major stream flowing down from Phu Luang, the waterfall forms a series of cascades, tumbling over rocky terraces and wide stone platforms into natural pools below. The water remains clear and refreshing all year round, with its most breathtaking scenery during the rainy season when the falls roar through the forest, filling the air with cool mist.

The trail to the waterfall serves as a designated nature study route, approximately 5 kilometers round-trip. It is suitable for all levels of visitors, particularly those who enjoy one-day hiking trips. Along the path, visitors pass through bamboo groves and lush forests rich in moss, ferns, and diverse plant species. Wildlife such as birds, butterflies, and small forest animals are often spotted, turning the hike into both an adventure and a learning experience.

Huai Phai Waterfall has also been certified as a Health and Wellness Tourism Destination by the Department of Thai Traditional and Alternative Medicine, emphasizing the site’s role in promoting both physical and mental well-being. Visitors can also learn about local herbal plants and their connection to traditional Thai wisdom.

In addition, the area is equipped with interpretive signage for educational purposes, making it suitable for families, students, and eco-tourists alike. Park officers are available to provide guidance and ensure safety throughout the journey.

For travelers seeking an authentic nature-based experience, Huai Phai Waterfall is a must-visit. It is not only a scenic attraction but also a living example of the region’s rich biodiversity and the harmonious connection between humans, forests, and waterways.
