Mae Sa Waterfall

Mae Sa Waterfall drops through ten distinct tiers in the forest of Doi Suthep-Pui National Park, roughly 27 km north-west of Chiang Mai via Mae Rim. Each level has its own character — the lower tiers form wide, calm pools ringed by ferns and smooth granite, while the upper cascades narrow and accelerate over dark basalt shelves. The DNP manages the site, so expect a proper entrance gate, a signed trail, and a 100 THB entry fee for foreign visitors.

The lower five tiers are the most visited. Families with small children tend to stop around tier three or four, where wide flat rocks make good picnic spots and the wading pools are shallow enough to be safe. The path here is paved and mostly shaded. On weekends these lower levels fill up fast — Thai families arrive in force and the sound of children drowning out the water is, depending on your mood, either charming or a cue to push on upward.

Insider Tip: Tiers six through ten see dramatically fewer visitors. The trail turns to packed dirt and gets genuinely steep in places, with exposed roots and the occasional rope assist on the slippery sections. The reward is relative solitude and the strongest cascades on the mountain — the eighth tier drops almost vertically into a narrow pool, with mist carrying down the canyon walls. Bring a dry bag for your phone.

The rainy season between June and November brings the waterfall to full power. All ten tiers run at capacity, the forest is deep green, and the upper sections carry a constant cool mist. The trade-off is a slippery trail — rubber-soled shoes with grip are not optional. From December to May, the flow is lighter but still present at every tier, the path dries out considerably, and you are less likely to share a pool with thirty strangers. Mornings beat afternoons here all year: cooler air, better light through the canopy, and the park is quiet before tour groups arrive from about 10:00.

Getting here independently is straightforward if you’re on a motorbike or have a car. Head north from Chiang Mai on Route 107, turn left at the Mae Rim intersection, and follow the Mae Rim–Samoeng Road for around 12 km — the entrance is signed clearly. The Huay Tung Tao Reservoir sits on the same road back toward Mae Rim and makes a natural second stop on the same day. Public transport is workable but slow: songthaews (shared red truck taxis) from Chang Phuak station reach Mae Rim, but the final stretch requires chartering a vehicle or booking a Grab. Most visitors pair Mae Sa with a rented motorbike loop along the Mae Rim–Samoeng route, which passes several orchid farms, an elephant camp, and Queen Sirikit Botanical Garden along the same stretch of road.

Watch out: Mae Sa is a national park — no dogs or other pets are permitted on site. This is a DNP-wide rule, strictly enforced. Leave any animals at home.

The waterfall does not have a restaurant on site, though there are food stalls near the car park selling grilled corn, fried snacks, and drinks. Bring your own water for the upper trail; it is a proper hike and the stalls are only accessible at the entrance level.
