Select participants and date
You step out of Kathmandu’s dust into a cool, green silence as the road slopes north toward Sundarijal. The river ahead seems to hurry off on its own errand, chattering over rocks while shaded trails pull you into the forest. By the time the city’s noise is a thin memory, oak and rhododendron register each footfall; the woods push you upward, then suddenly open to a ridge where Himalayan air feels like a promise.

Adventure Tips
Acclimatize in Kathmandu
Spend 1–2 days in Kathmandu before departure to reduce acute altitude sickness risk and adjust to the culture and logistics.

ATMs don’t operate beyond Dhunche; bring Nepali rupees for tea-house bills, tips and small purchases.
Layer for variable temps
Temperatures swing from hot valley hikes to freezing nights above 4,000 m; pack breathable base layers and an insulated jacket.
Respect pilgrimage sites
Gosainkunda is sacred—keep noise low, avoid swimming, and follow local customs at lakes and gompas.
