Most waterfalls in Chiang Rai are within national parks.
Just 17km southwest of the city centre, Khun Korn Waterfall is the tallest and, arguably, the most spectacular waterfall in Chiang Rai. At 70 metres high, the water plunges straight down in one powerful motion, sending off mists that float through the air tens of metres away. The hike to the waterfall, itself is a major highlight, takes about 45 minutes along the 1.2km, forest-fringed path that cuts through several cascade pools and over bamboo bridges. On the opposite scale, but by no means less beautiful, Huay Mae Sai Waterfall is set amongst Akha and Lahu ethnic hill-tribe communities about 19km northwest of the city centre. This two-tier fall has a still pool where you can go for a dip and is also ideal for elephant trekking.
