The highest mountain in Indochina (Laos, Cambodia and Vietnam) might seem as a easy trekking peak due to the not so impressive height of only 3,143 m, but don't be fooled. The are several routes to the top, but every track is difficult and involves a overnight stay unless you do commando raid (record is around 10 hours up and down from Heavens Gate at 1,949 m). A lot of scrambling on slippery rocks and zigzagging through dense bamboo forest is the norm, and expect bitterly cold and wet nights. To get the full experience, it's highly recommended to descend on the southeast side into the Sapa valley over multiples days. Coming down from the top covered in dense forest and trekking into the farmed valley with rice terraces and villages is a rewarding finish.
