tl;dr
Four waterfalls near Pai make four completely different days out: natural rock slides and swimming pools in the sun at Mor Pang, a shaded gorge you walk straight into at Pam Bok, a half-day river walk at Hua Chang, and a full-day jungle trek at Mae Yen.
The short answer
- Mor Pang
- For those wanting a waterfall in the sun and a proper swim
- Pam Bok
- For those wanting a true vertical-drop waterfall that’s close to town
- Hua Chang

Easy swims near town: Mor Pang vs Pam Bok
If you want to cool off without spending hours hiking up a river, your choice is between Mor Pang Waterfall and Pam Bok Waterfall. Both are a 15 to 20 minute scooter ride from Nolo Hub Pai on paved roads, and neither requires a trek.
Go to Mor Pang (10.5 km west, 100 THB) if you want sunshine, space to hang out on the rocks, and a proper swim. Water pours down broad, sloping rock chutes into two pools, with food stalls at the car park and free toilets and changing rooms on site.
Go to Pam Bok (8.2 km south-west, 200 THB) if you want a tall, vertical-drop waterfall tucked inside a narrow, high-walled gorge. A 100 to 150 metre walk from the parking area brings you to the shaded plunge pool at the foot of the falls. Because the gorge stays in shade for much of the day, the water is noticeably colder than Mor Pang’s — and your date-stamped 200 THB Lum Nam Pai Wildlife Sanctuary pass also gets you into Sai Ngam Hot Spring on the same day for just the 30 THB scooter fee there.
Jungle river treks: Hua Chang vs Mae Yen
Hua Chang and Mae Yen aren’t roadside stops — both are wet jungle hikes where the trail criss-crosses the river dozens of times on the way up to the falls.
Hua Chang (3–4 hours round trip, free) gives you the full river-crossing experience in half a day, following the river upstream through 16 to 22 crossings each way — ankle-deep when it’s dry, up to knee height after rain — with an anchored rope down a short rock section at the end. Mae Yen (6–7 hours round trip, carry 300 THB) is a full-day expedition with 30 to 40 stream crossings each way and a steep climb over a forested spur before dropping down to a 30-metre waterfall.
Hua Chang
- River crossings
- 16–22 each way
- The ground
- Mostly flat and wet, with a rope at the end
- Finding the way
- Navigate yourself up the river; save a recorded track; the trail fades near the falls
- Alone?
- Not if you’re unsure of your route-finding or the river crossings
- Turn back by
- Leave the waterfall by 4pm
- When the water rises
- Don’t start after heavy rain; turn back if the river rises, turns muddy or gets hard to cross
- Footwear
- Sandals or water shoes with grip
Mae Yen
- River crossings
- 30–40 each way
- The ground
- Gentle for 5 km, then a steep climb over a spur
- Finding the way
- Save a track or go with someone who knows it; there are three places people go wrong
- Alone?
- Don’t go alone
- Turn back by
- Leave the waterfall by 2pm
- When the water rises
- It can rise 1.5–2.5 m within an hour of heavy rain in the hills; if it’s running high, leave it for another day; turn back if it rises or turns muddy
- Footwear
- Shoes or hiking sandals with grip
There’s no phone signal on either trek, so save an offline GPS track before you leave Pai and tell reception where you’re going and when you’ll be back: if you’re not, we contact Pai Rescue and the Tourist Police. Leave the flip-flops at home.
Best time of year for Pai’s waterfalls (and seasonal closures)
The rains in Pai run from mid-May to October, the cool dry season from November to February, and burning season, when the haze builds, from March to May. (For how the whole valley changes month by month, see our best time to visit Pai guide.)
- Mor Pang runs all year; the flow gets lighter in the hot months just before the rains. After heavy rain, don’t use the rock slides.
- Pam Bok is at its strongest during and right after the rains, and can slow to a trickle in the hot months before they come back. Because the gorge funnels runoff from the hills above, if the water rises or turns muddy while you’re inside, leave the gorge straight away.
- Hua Chang and Mae Yen are at their best in the cool, dry months after the rains (November to January), when the waterfalls still have strong flow and the stream crossings are calmer. Don’t start Hua Chang after heavy rain, and leave Mae Yen for another day if the stream is running high; on either trail, turn back immediately if the water rises or turns muddy.
- Burning-season closures (mid-February to April): Rangers usually close the Hua Chang trail in burning season, roughly mid-February to April, and Mae Yen can close at times too. Ask us at reception before you set out.
Pairing Pai’s waterfalls (and visiting without a scooter)
- Pam Bok and the Kho Ku So Bamboo Bridge sit on the same south-west valley road — the bridge is just 1.8 km past Pam Bok’s entrance, and it’s easy to finish the afternoon at Pai Canyon for sunset.
- Keep your Pam Bok ticket for a hot spring soak: Pam Bok’s 200 THB sanctuary pass is date-stamped and covers your entry at Sai Ngam Hot Spring (north-west of town) on the same day, so you only pay the 30 THB motorbike fee (or 60 THB for a car) at Sai Ngam’s gate.
- No scooter? Join a day trip: Mor Pang is on Nolo Hub Pai’s Pai Landmarks day trip on Mondays and Thursdays, with Santichon and Yun Lai Viewpoint, the White Buddha and Pai Canyon. Nolo Hub Pai’s trips don’t go to Pam Bok, so without a scooter it’s a private truck with a driver, or a motorbike taxi that waits for you — see getting around Pai without a scooter.
Quick answers
Which waterfall in Pai is best for swimming?
Mor Pang Waterfall (10.5 km west of Pai, 100 THB entry) is the best all-round spot for swimming and hanging out in the sun, with two pools, natural rock slides on the middle tiers, food stalls at the car park, and free toilets and changing rooms. Pam Bok Waterfall (8.2 km south-west, 200 THB) also has a plunge pool inside a shaded gorge for a cold dip when the water is calm.
Are any waterfalls in Pai free to enter?
Hua Chang Waterfall (a 3–4 hour half-day river trek north-east of Pai) is completely free. Mae Yen Waterfall (a 6–7 hour full-day jungle trek east of town) has no permanent ticket booth and is usually free, though mobile national park rangers occasionally collect the 300 THB Huai Nam Dang National Park fee at the trailhead. Mor Pang costs 100 THB and Pam Bok costs 200 THB.
Which Pai waterfall shares a ticket with Sai Ngam Hot Spring?
Pam Bok Waterfall. Its 200 THB Lum Nam Pai Wildlife Sanctuary day pass is date-stamped and covers your admission to Sai Ngam Hot Spring on the same day — you only pay the 30 THB motorbike fee (or 60 THB car fee) at Sai Ngam’s gate.
Can you visit Mor Pang and Pam Bok Waterfalls without a scooter?
Mor Pang, yes: it’s a stop on Nolo Hub Pai’s Pai Landmarks day trip on Mondays and Thursdays. Nolo Hub Pai’s trips don’t go to Pam Bok, so without a scooter you’d need a private truck with a driver, or a motorbike taxi that waits for you.
