Lam Nam Kok and Huai Kael waterfall

A fantastic loop in the middle of the jungle with a wide trail for 80% of the hike.
The waterfall halfway through is worth the detour!
The trail is generally quite wide and does not require any technical skills. Be careful of the intense heat of Southeast Asia.
Crying Dog Waterfall

This circuit is just the start of a longer walk. The hike ends at this small waterfall, but the path continues much further. This is a perfect short hike to combine with a visit to the famous Wat Phrathat Doi Sutherland temple, which is right next door.
The first third of the hike is on a road and isn't very interesting. However, the rest is a paradise for hikers, with a unique, wide trail through dense forest.
