Mon Hin Lai Waterfall is one of Chiang Mai’s true off-road waterfall destinations, not easily accessible but highly rewarding for travelers who genuinely enjoy wild nature. The waterfall is located in the Mae Ngat forest area of Phrao District and is under the supervision of Sri Lanna National Park. The final access route requires a four-wheel-drive vehicle. What makes this waterfall special is not a quick photo opportunity, but its geological character: a series of sloping rock cascades stretching across nine levels. Exploring each tier feels like reading the landscape page by page, revealing forest humidity, smooth rock surfaces shaped by flowing water, and the rhythm of streams that changes with the seasons.

 

Mon Hin Lai Waterfall has flowing water year-round, though its character varies clearly by season. During the rainy season, water volume is high, the sound of cascading water is powerful, and the forest turns deep green. This beauty comes with increased risks, including slippery trails and the possibility of sudden flash floods after heavy rain in upstream areas. The cool season is often considered the best time to visit, with comfortable temperatures that allow longer walks and clearer views of rock layers and pools. In the dry season, water levels may decrease, but the structure of the sloping rock terraces and the watercourse becomes more visible, making it ideal for visitors interested in geography and ecosystems rather than swimming.

 

The highlight most frequently mentioned by visitors is the ninth tier, the highest level, which connects to the summit area known as Mon Hin Lai Peak. From here, visitors can enjoy panoramic views over Phrao District. This area also features a nature study trail of approximately one kilometer, suitable for those who wish to explore the forest at a slower, more observant pace. From this perspective, the waterfall is appreciated not only for its beauty but also for how a multi-tiered waterfall functions as a living water system, with resting pools, acceleration points, branching streams, and areas where water converges again.

 

Getting There From Chiang Mai city, take the Chiang Mai–Phrao route, covering approximately 85 kilometers to the Phrao area. From there, connect to the road toward Mae Ngat Somboon Chon Dam and continue toward the waterfall. The final section involves about 14 kilometers of unpaved dirt road. A four-wheel-drive vehicle is strongly recommended, especially during the rainy season when the surface can become slippery and deeply rutted. Allowing extra travel time and driving cautiously can significantly reduce risks.

 

For travelers wishing to extend their visit overnight, a commonly mentioned camping area is Huai Kum, located along the Ping River near a ranger station. Availability and conditions may change depending on park management and seasonal regulations. The area is suitable for those seeking a quiet forest-and-river atmosphere. Visitors should prepare essential equipment, including flashlights, insect repellent, rain gear, and proper footwear suitable for wet and uneven terrain.

 

To help preserve the area and reduce the burden on both nature and park staff, visitors are encouraged to carry their own trash bags, avoid disposing of food waste in streams, refrain from using soap or shampoo in natural water sources, and keep noise levels low. Watershed forests like this are more fragile than they may appear, especially during the rainy season when riverbanks and rock surfaces can be dangerously slippery.
