Escape Kathmandu’s bustle for 13 days of remote ridgelines, mountain lakes and village hospitality in Nepal’s eastern Himalaya. This trek balances steady climbs, high viewpoints and authentic local culture while staying largely off the main trekking corridors.
More ways to explore the area's outdoor wonders
A thin light warms the high roof of the Kathmandu valley as jeeps rattle out toward the Arun River, and by evening you’ll be trading traffic for terraced fields and the chatter of village life. The Arun Valley trek unfurls east of Kathmandu through deep river gorges, rhododendron and bamboo forests, and high alpine bowls — the landscape shifts each day like chapters in a field guide.

Reserve your spot on the 13 Days Arun Valley Trek from Kathmandu today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize deliberately
Take a lighter day or an extra night before ascending above 3,000 m—symptoms of AMS can appear quickly and steadily.
Treat your water
Bring a UV purifier or chemical treatment—village water is available but not reliably safe without treatment.
Sturdy footwear
Choose broken-in, ankle-supporting boots; trails can be rocky and slippery after rain.
Carry cash
ATMs are rare beyond Khandbari and Phaplu; carry Nepali rupees for tea houses and permits.
Broken-in mountaineering/hiking boots
Support and grip for mixed rocky, muddy and rooty trails.
Layered clothing system (base, insulating, shell)
Rapid weather shifts at altitude require breathable layers and a waterproof shell.
Water-treatment (UV pen or chemical tabs)
Reliable method to treat village or stream water and avoid gastrointestinal illness.
Lightweight sleeping liner and warm hat
Extra warmth in guesthouses where blankets vary in quality, especially in cooler months.
