Sticky Waterfalls Chiang Mai (Namtok Bua Tong): Climbing Guide & How to Get There
Written by Pim Meijboom, Co-Founder of PM Tours. I've visited hundreds of waterfalls across Thailand, and Bua Tong is the only one that defies physics, you can literally run up a vertical wall of water like Spiderman. It sits inside the Bua Tong–Nam Phu Chet Si park area in Mae Taeng, and it's my favourite spot to take visiting friends. One warning from experience: it's far from the city, and Grab drivers often refuse the return trip. Here's how to visit safely and get home without stress.
Quick answer: The Sticky Waterfall (Namtok Bua Tong) is a limestone waterfall about 60 km / 1.5 hours north of Chiang Mai in Mae Taeng District. Its calcium-carbonate rock has a natural grip, so you can climb up the falls barefoot without slipping. Entry is free, it's open daily 8:00 AM–5:00 PM, and most people spend 1.5–2 hours here. Go on a weekday before 11:00 AM to avoid crowds. There's no direct public transport, so most visitors drive, hire a private car, or join a guided tour.
Sticky Waterfalls: Fast Facts
Thai name: Namtok Bua Tong (also spelled Bua Thong)
Also known as: The Sticky Waterfall
Location: Mae Taeng District, ~60 km / 1.5 hours north of Chiang Mai Old City
Entrance fee: Free (you register your name and vehicle at the gate)
Opening hours: Daily, 8:00 AM–5:00 PM, year-round
Size: Three main tiers, roughly 100 metres of climbable cascade
Why is it sticky? A mineral crust of calcium carbonate (tufa limestone) gives the rock a sponge-like grip. No moss grows on it — so it's not slippery.
Difficulty: Easy to moderate. Suitable for active kids aged 5+. Ropes assist on steeper sections.
Climb time: 20–45 minutes, depending on how high you go
Best time: Weekday mornings before 11:00 AM; dry season (November–April) for easiest climbing
What is the Sticky Waterfall, and why is it sticky?
The Sticky Waterfall is a multi-tiered limestone waterfall that you can climb - up and down - using nothing but your bare feet. That's what makes it unique in Thailand, and why it draws visitors from all over the world.
The "stickiness" is pure geology. The water comes from the Nam Phu Chet Si spring above the falls, and it's rich in calcium bicarbonate. As that water hits the air, the mineral crystallises on the rock, building a rough, porous crust called tufa limestone. This crust grips the soles of your feet, and because the minerals stop moss and algae from forming, the surface stays clean and non-slip. Most waterfalls in Thailand are dangerously slippery; Bua Tong is the opposite.
The falls drop over three main tiers totalling around 100 metres. Lower sections are gentle enough for a first-timer, while the upper tiers are steeper and more of a challenge. You climb entirely at your own pace, and ropes are fixed along the steeper parts for support.
Is the Sticky Waterfall worth visiting?
Yes, for most travellers it's one of the best half-day trips from Chiang Mai. It's free, it's genuinely unlike anything else in Thailand, and it suits families, couples, and solo travellers alike. The main trade-off is distance: it's a 1.5-hour drive each way with limited public transport, so the effort of getting there is the real "cost." If you have half a day and want an active, memorable outing, it's well worth it. If you're short on time and staying central, weigh the travel time before committing.
Is it free, and what are the opening hours?
Entry to the Sticky Waterfall is free. There's no ticket booth, you simply register your name and vehicle at the entrance. Parking is free as well. The park is open every day from 8:00 AM to 5:00 PM, including weekends and holidays. Arriving right at 8:00 AM gives you the quietest experience and, often, the falls almost to yourself.
What is the best time to visit?
The best time to visit is a weekday morning during the dry season (November–April). In the dry months the water flow is lower and the rock is at its grippiest, making the climb easiest and safest. Daytime temperatures are pleasant, roughly 20–30°C (68–86°F).
That said, the falls are open year-round and each season has its appeal:
Cool/dry season (Nov–Feb): Most comfortable temperatures, easiest climbing, peak crowds.
Hot season (Mar–Jun): Lower water, still very climbable, fewer visitors midweek.
Rainy season (Jul–Oct): Strongest, most exhilarating flow and the greenest jungle. Take extra care on steeper sections after heavy rain.
Whatever the season, come before 11:00 AM on a weekday to beat the tour buses and local weekend crowds.
How to get to the Sticky Waterfall from Chiang Mai
The Sticky Waterfall is about 60 km north of Chiang Mai in Mae Taeng District, roughly a 1.5-hour drive. There is no direct public transport, so you'll need one of the options below. Here's how they compare:
Rental motorbike

Guided tour
Rough cost: From ~2,000 THB pp

Notes: Transport, guide, lunch, entry and insurance handled for you.
A word from experience: the biggest headache here isn't getting to the falls, it's getting back. Because the waterfall is remote, Grab and taxi apps regularly show no available drivers for the return leg, and many drivers who take you there won't wait. If you go independently, either arrange a return time with your driver in advance or ride a rented vehicle. If you'd rather not gamble on it, a guided tour removes the problem entirely.
What to expect when you climb
From the car park, wooden staircases lead down to the falls. You can then climb the cascade itself. Most visitors reach the second or third tier and wade in the pools at each level. The full climb takes 20–45 minutes at a relaxed pace, and you can descend the same way or take the forest path alongside.
A few practical tips:
Go barefoot. Bare feet grip the tufa best. Water shoes are a decent second choice; avoid regular trainers.
You will get wet. Bring a change of clothes — there are changing facilities on site.
Use the ropes on the steeper upper sections, especially with children.
Swimming: there are small natural pools at the base for a refreshing dip, though the main draw is the climb, not swimming.
Facilities: restrooms, picnic areas, and a small kiosk/restaurant are available near the entrance.
Don't miss the short walk above the main falls to the Nam Phu Chet Si spring, the "Seven Colours" spring that feeds the waterfall. It bubbles up in a striking blue-green pool and is the source of the minerals that make everything below it sticky. It's about a 15-minute walk if you have the time.
Visiting the Sticky Waterfall as Part of a Tour
Joining a tour is one of the easiest ways to visit, it removes the transport and return-trip hassle, and a guide can explain the geology and lend a hand if you're nervous on the climb. It's also a good way to meet other travellers. PM Tours runs two Sticky Waterfall tours, each with a different focus.
Doi Suthep and Sticky Waterfalls Tour
A one-day tour combining Chiang Mai's best cultural and natural highlights. Hotel pick-up is 8:00–8:30 AM. You'll visit the iconic mountaintop temple Wat Phra That Doi Suthep with its panoramic view over the city, the forest-hidden Wat Pha Lad, and an orchid farm, before lunch and the main event, climbing the tiers of Bua Tong. You're returned to your hotel around 4:00 PM.
Included: entrance fees, English-speaking guide, lunch, drinking water, insurance, and return hotel transfer. Price: 2,000 THB
Sticky Waterfalls Trekking — One Day Tour
A one-day jungle trek through the rainforest around the falls. The route starts at the Hidden Cave and follows forest trails to the Fountain of Seven Colours spring, where fast-flowing limestone water sparkles in the sunlight. The trek is about 5 km, rated mild/easy, with plenty of breaks. After a Thai lunch you continue to the Sticky Waterfall to climb the tiers at your own pace, returning to your hotel between 3:30 and 4:00 PM.
Included: transport, all entrance fees, English-speaking guide, lunch, drinking water, and insurance. Price: 2,000 THB
