Unique limestone waterfall near Chiang Mai you can climb barefoot due to grippy mineral deposits. Fun and photogenic.
Bua Thong Sticky Waterfall (Nam Tok Bua Thong) is a series of limestone cascades in the Mae Taeng area of Chiang Mai Province, approximately 70 kilometres north of Chiang Mai city. The waterfall is named 'sticky' because the limestone surface of the rock face is coated in a calcium carbonate deposit left by the mineral-rich spring water, giving the stone an unusually grippy texture compared to ordinary waterfall rock. Visitors can walk barefoot directly up the flowing waterfall surface — climbing a cascade that would be completely impossible on normal smooth rock — making it a genuinely distinctive and interactive experience unique in Thailand. The water flows in thin sheets across a pale cream-coloured travertine shelf approximately 30 metres high, surrounded by bamboo and broadleaf forest. Multiple natural terraces allow resting and wading in calm pools between climbing sections. The falls flow year-round from a spring source above, fed by groundwater rather than surface runoff — meaning the volume and temperature of the water remain relatively consistent regardless of season, and the falls do not turn muddy or dangerous during rainfall as surface-fed waterfalls do. The site is maintained by a local municipality and has basic facilities: a small car park, a covered rest area, and food and drink vendors. Admission is free. Most visitors come as part of a Chiang Mai day trip combined with other nearby attractions such as the Chiang Dao cave or the Maesa Elephant Camp.

- Multiple natural ledges and pools for resting and wading between the climbing sections
- Year-round consistent flow from a groundwater spring — not affected by season or rainfall
- Free entry with a genuine natural phenomenon unique in Thailand
Tips for visiting
- Go barefoot — the limestone grip works best with bare feet, not water shoes or sandals
- Wear clothes you are happy getting completely wet; the climb involves full immersion at several points
- Bring a dry bag for phones and cameras; waterproofing is essential for any electronics
- The falls are most enjoyable in the morning before midday sun makes the unshaded upper sections hot
- Combine with Chiang Dao cave (40 km north) for a full day trip from Chiang Mai
When to visit
The falls are worth visiting year-round given the consistent water flow. Morning visits (before 11 am) are more comfortable as the unshaded upper sections of the travertine face can become hot in the afternoon sun. November through February offers the most comfortable ambient temperatures.
Accessibility
The waterfall itself cannot be accessed by wheelchair users due to the sloping water surface and uneven terrain around the base. The path from the car park to the base of the falls is a short, relatively flat walk of about 100 metres on a concrete path, accessible for most mobility levels. The climbing portion of the experience is not accessible for those with limited balance or lower-limb mobility.
Frequently asked questions
Is the Sticky Waterfall actually climbable?
Yes. The calcium carbonate coating on the travertine rock provides genuine grip under bare feet. Most adults with reasonable balance can climb the full height of the falls. Children from about age 5 upwards can typically manage the lower sections with supervision.
How do visitors get to Bua Thong Sticky Waterfall from Chiang Mai?
The falls are about 70 kilometres north of Chiang Mai on Highway 107 toward Chiang Dao. A scooter or car takes approximately 90 minutes. Organised day tours from Chiang Mai include the falls as a stop; taxis can be arranged for the round trip (around 1,000–1,500 baht).
Is the waterfall open year-round?
Yes. Because the water source is a groundwater spring rather than surface runoff, the falls flow consistently throughout the year. There is no seasonal closure, and the water volume and clarity do not fluctuate significantly with rainfall.
