Why should you go there and how do you do it right?

One of the more challenging hikes in the Pai region leads to Mae Yen Waterfall. Visitors willing to earn their reward on a 14-15 kilometer trail through densely forested mountain terrain will be richly rewarded. Characteristic of the route are the numerous river crossings—around 40 in each direction—so wet feet are guaranteed and part of the experience. The waterfall itself lies at the end of a mostly well-maintained path, although the last kilometer before the waterfall has one particularly slippery section.

Visitors can expect a pristine, intense jungle atmosphere with minimal infrastructure and few other hikers. The circular hike typically takes between three and a half and five hours, depending on pace. After the first thirty minutes, the trail becomes increasingly indistinct, making navigation more challenging in addition to the physical exertion. The pools at the waterfall are a definite reward for the effort, and the repeated river crossings lend the hike an adventurous character that sets it apart from the region's more developed natural attractions.
