You’ve done the popular Himalayan treks, and the crowded trails no longer feel like an adventure. Long queues at campsites and littered paths take the wildness out of the mountains.
Meanwhile, one of India’s most remote high-pass routes sees only a handful of groups each season. The Bailey Trail trek in Arunachal Pradesh crosses four high passes, empty alpine valleys and Monpa grazing lands, with hardly another trekker in sight.
This guide covers everything you need: the route map, distance, cost, packages, permits and the best season to go.

A Trail Shaped by History
The route takes its name from Lt. Col. F. M. Bailey and Capt. H. T. Morshead, British officers who explored and surveyed the eastern Himalaya in 1913. Their survey work fed into the frontier maps that later shaped the McMahon Line.
Before that, Monpa herders and traders used these passes for centuries. Today, old army bunkers near Thungri remind you of the trail’s strategic past.
Four High Passes in One Trek
Few treks in India pack this many high crossings into six walking days:
- Poshing La — about 3,950 m
- Pangi La — about 4,200 m
- Tse La — the high point, roughly 4,900–4,980 m
- Sela Pass — about 4,170 m, crossed by road on the way out
Remote Monpa Villages and Mago
On the descent you reach Mago, a remote Monpa village near the Tibet border. Expect yak pastures, prayer flags, simple homestays and warm hospitality after days of camping.

Difficulty and Fitness Prep for Experienced Trekkers
Operators grade this route anywhere from moderate to challenging. However, long days above 4,000 m, steep pass crossings and an often unmarked trail make it best for trekkers who already have high-altitude experience.
- Have at least one 4,000 m+ trek behind you
- Train for 6–8 weeks: stair climbs, loaded hikes and 5 km runs
- Hire a local guide; the trail is remote and poorly marked
- Plan an extra buffer day for weather or acclimatisation
