Mo Paeng Waterfall sits at Ban Mo Paeng in Mae Na Toeng sub-district, Pai. It's a mid-sized waterfall that runs nearly year-round, split into several tiers. The rock up top is worn so smooth that people love to sit and slide down it like a natural water slide, ending up in the pool below that's deep enough to swim in. The real draw here isn't dramatic height — it's the shady forest setting and the chance to cool off in the water this close to town.
Why people love Mo Paeng Waterfall
- It has a natural rock slide — the middle tier has been worn smooth by years of running water, and people slide down it into the pool for fun. This is the highlight most visitors come for.
- There are pools to swim in — the middle tier forms a wide pool where the water is calmer than up top, good for a soak and a swim.
- Close to Pai town — only about 8-9 km away, an easy morning trip with no need to stay overnight.
- Shady and cool — it's set in a rubber forest, and it's less than a minute's walk from the car park to the falls.
- Food stalls and rest shelters — near the car park there are stalls selling snacks and shelters where you can sit, eat, and rest.

How many tiers does Mo Paeng have, and where is it safe to swim?
Mo Paeng Waterfall has around 3 tiers, with a modest total height of about 5 metres and a width of 10-15 metres. Each tier has its own feel. The tier where most people swim and use the slide is the middle tier, because the pool is wide, the current isn't too strong, and it's an easy walk from the car park.
- Lower tier — the first one you see from the path, shallow water, good for photos and dipping your feet.
- Middle tier — the largest pool, and the main spot for the rock slide and swimming. It's safer than the others.
- Upper tier — you have to climb the rocks to reach it, the current runs stronger, and the rock is very slippery. Not recommended for kids or weak swimmers.
Watch the slippery rock
The name "natural slide" tells you straight up that the rock here really is slippery — and the area around it is too. Walk slowly, hold on firmly, and wear non-slip shoes (flip-flops slide easily). Before you sit down to slide, check that the pool below is deep enough and clear of jutting rocks, and don't slide when the current is strong during heavy rain.
Getting to Mo Paeng Waterfall
Mo Paeng Waterfall is west of Pai town. Take Highway 1095 (the Pai-Mae Hong Son route), pass the hospital and Pai airport, then watch for the signs to the waterfall/Mo Paeng, turn off and follow the road a little further to the car park. It's about 8-9 km from town in total, roughly a 15-20 minute motorbike ride.
- Rent a motorbike — the most convenient option. Rental shops in Pai town start at around 150-200 THB/day, and you're free to ride at your own pace and stop off elsewhere along the way.
- Songthaew / chartered ride — if you'd rather not drive, you can hire a songthaew or a private ride from town. Agree the price before you get in.
- Bicycle — doable, but there are some uphill stretches that are fairly tiring, so it suits keen cyclists.
Take care riding the mountain road
The final stretch up to the waterfall is a winding mountain road with some steep sections. If you've never ridden a motorbike before, don't make Pai the place you learn. Always wear a helmet, check your brakes before you set off, and watch for slippery roads after rain.
Entry fee and facilities
On the entry fee for Mo Paeng Waterfall, the information from different sources doesn't agree. At some times, or in some accounts, it's free; others mention a fee of around 50 THB for Thais and 100 THB for foreigners. It likely depends on the time and how the community is managing the site. We'd suggest carrying some cash just in case — and if there is a parking or entry fee, consider it a contribution to looking after the place.
- Car park — there's a shaded car park, less than a minute's walk from the falls.
- Food and drink — a few stalls near the car park sell snacks and drinks.
- Shelters / rest areas — there are shelters and grassy spots to sit, eat, and rest.
- Toilets / changing rooms — basic ones are available. Bringing spare clothes and a dry bag of your own makes things easier.
When is the water high, and when is it low?
Mo Paeng Waterfall does run nearly all year, but the volume clearly changes with the season. If you're coming to swim and use the slide, the sweet spot is late rainy season into early winter (around October-December), when the water is clear, cool, and not so strong that it's dangerous.
- Rainy season (Jun-Sep) — high water and a strong flow. It looks great but you have to be careful; during heavy rain the water can turn muddy and fast, and it's not a good time to get in.
- Late rains into early winter (Oct-Dec) — the best balance: just the right amount of water, clear, and the weather is lovely.
- Hot and dry season (Mar-Apr) — lower water, and in some spots there's only enough to dip your feet, so the slide may not be slick enough to use. This is also when Pai often has haze and smoke from burning, with poor visibility and air quality. Honestly, it's not the best time to come.

Mo Paeng Waterfall is on the western side of Pai, the same direction as several other sights, so it's easy to build into a half-day loop. Near Ban Mo Paeng there's also a Red Lahu (Musur Daeng) hill-tribe community, where many people stop to see daily life and pick up handicraft souvenirs.

Get ready before you go
Wear your swimwear from your accommodation, or put it on under your clothes — that's easiest. Bring a towel, spare clothes, a dry bag for your phone, non-slip shoes with a heel strap, and drinking water. Don't leave valuables lying around near the pool.
