Short answer
Sticky Waterfall, properly Bua Thong, is a limestone waterfall about 60 km north of Chiang Mai, a drive of roughly 90 minutes according to the Tourism Authority of Thailand. Its rock is rough enough that visitors can climb the tiers without slipping. A travel blog reports free entry, and a 2021 Thai report gives opening hours of 08:00 to 17:00, but we found no official fee notice, so check at the gate. Wear shoes with grip, go early and expect three to four tiers. Our Doi Inthanon tour visits a different waterfall.
What Sticky Waterfall is, and why the rock is sticky
Wikivoyage's Chiang Mai guide calls Bua Tong Waterfall the "Sticky Waterfall", famous for non-slippery limestone rocks that let visitors climb up the falls without slipping. The Tourism Authority of Thailand (TAT) described it in May 2021 as a multi-tiered cascade whose limestone walls are surrounded by forest and are sticky enough to be climbed.
A Thai travel report from TrueID in 2021 explains the rock: the waterfall is a stream of hard limestone covered with calcium carbonate, with clear water that flows all year. It says the waterfall has three or four tiers over a length of only 250 metres, so the climb itself is short. The travel blog Two Wandering Soles credits a mineral-rich spring at the top for the porous, grippy rock.
Where it is and how far: 60 km north, about 90 minutes
Wikivoyage puts Sticky Waterfall 60 km north of Chiang Mai, and TAT describes a 90-minute drive from the city. TrueID gives the route: take the Chiang Mai to Phrao road, turn right at kilometre 48 to 49 into the park, then drive almost 3 km to the car park before walking to the falls. It lies in Mae Ho Phra sub-district of Mae Taeng district.
TrueID places the waterfall inside the Namtok Bua Thong and Nam Phu Chet Si National Park. Two Wandering Soles says to follow Route 1001 north of the old city and look for the sign on the right. The drive each way is about an hour and a half, so the round trip is about three hours on the road, plus time at the falls. We could not confirm a regular public songthaew or bus service there.
What it costs: free entry reported, and the transport price is yours to negotiate
Two Wandering Soles, in a post updated in December 2025, says entry is free and there are no entrance or parking fees. A list of Thai national park closures published by TAT, with data as of 6 June 2024, shows the park as number 151, marked "in preparation", with no closure period listed. We found no official notice of a fee, so check at the gate.
Transport is the real cost. The same blog says a return songthaew costs anywhere from 800 to 1,500 baht depending on bargaining, that 1,500 baht is the going rate for a driver who waits, and that a Grab ride costs about the same. It says a motorbike rents for around 200 baht a day, and that the law requires an international driving licence. These are a blogger's figures, not official fares.
Hours, best season and what to do about crowds
TrueID's 2021 report lists opening hours of 08:00 to 17:00, and Two Wandering Soles says it gets busier around midday, so it recommends arriving early. TrueID says the waterfall looks best in the rainy season and early cool season, and tells readers to check the park's annual closure first. TAT's 2024 closure list shows no closure period for this park, but the situation can change, so ask before you drive.
Because the water flows all year, according to TrueID, the waterfall works in the dry season too. TAT's January 2026 feature on northern winters says that when Chiang Mai cools from November to February, the crisp air makes outdoor activities more comfortable. Two Wandering Soles adds that you can pack a picnic or buy drinks and light snacks from the vendors in the area.
The climb: tiers, shoes and rules
TrueID describes the tiers one by one. The first has a small pool for sitting in. The second is shallow with a gentle flow, which it calls suitable for small children. The upper tiers have deeper pools and a stronger flow, which suit adults. Most visitors only go as far as tier 3, because the path ends there. To reach tier 4 you must climb along the waterfall itself, which TrueID says may be dangerous.
On footwear, the sources disagree. TrueID says to wear shoes for safety, because bare feet feel numb on the rock, while Two Wandering Soles climbed barefoot. We side with the safety advice: wear grippy water shoes. Two Wandering Soles also says food is not allowed in the waterfall area, that there are picnic tables near the entrance, and that there are basic toilets, so bring tissue.
Who should go, and who should skip it
Go if you like short, active outings in the water and you have half a day to spare. Skip it if anyone in your group is unsteady on rock, or if you cannot spend about three hours on the road. TrueID says the shallow second tier suits small children, while the upper tiers are for adults. Two Wandering Soles suggests packing a swimsuit, a towel, a change of clothes, plenty of water and a dry bag.
If you would rather not organise transport yourself, ask your hotel about a hired driver, and agree the waiting time and the price before you leave. A songthaew can be chartered for the day, as our red truck guide explains. Whichever you choose, start early: TrueID gives an opening time of 08:00, and Two Wandering Soles says the falls get busier around midday.
Sticky Waterfall or our Doi Inthanon day?
Our elephant sanctuary and Doi Inthanon tour is from $40 per person and lasts 10 to 12 hours, with hotel pickup in the morning and lunch included. It includes a guided hike through forest and rice fields to a waterfall and a hill village on Doi Inthanon, which is a different waterfall from Bua Thong, and the Doi Inthanon fee of 300 baht per adult and 150 per child is paid on the day unless your quote says otherwise.
If climbing the sticky rocks is the reason you came, our tour will not do it, so plan a separate half day. Many visitors combine the two over a few days; our Chiang Mai three-day plan shows how. For the cost of getting around, see our red truck guide.
Practical checklist
- Start early: the waterfall opens at 08:00 and the drive takes about 90 minutes each way.
- Wear grippy water shoes, and bring a swimsuit, a towel, a change of clothes and a dry bag.
- Agree the price, the waiting time and the return with any songthaew or driver before you leave.
- Bring cash and do not count on food in the waterfall area, where it is not allowed.
- Ask before you drive about the annual closure, as Thai reports advise.
