A closer look

Forget paved tourist paths and welcome to a sheer drop-off masquerading as a hiking route. Reaching the Phuktal Gompa in the remote Zanskar region of India involves navigating tiny wooden bridges and dirt tracks carved directly into a vertical limestone cliff. The 12th-century monastery literally spills out of a massive cave mouth like a honeycomb, entirely inaccessible by road and requiring a multi-day trek that aggressively filters out travelers afraid of heights.
