Founder-Led Adventure Series
Once a month, MonkTrekker personally leads one small-group Himalayan journey — not a standard package, but a route chosen for what it teaches, not just where it goes. Expect backpacking over marked trails, unscheduled stops in villages most itineraries skip, campfire conversations that run late, and a pace built for actually being there, not just getting through it.

A 7-day backpacking route to Roopkund, capped at 12 trekkers so the group actually gets to know each other — and MonkTrekker. No fixed camps, no rush between checkpoints, and long enough away from signal that you'll notice it.
