A extreme-grade expedition to 8,188m in Khumbu, spanning 50 days from Kathmandu to summit and back. This 50-day journey through Khumbu takes you far beyond the reach of teahouses and lodges — every night is spent under canvas, with a dedicated cook crew preparing hot meals at camp. Expect gradual, well-paced acclimatization days built into the route, genuine wilderness immersion, and the kind of remote trail experience that's increasingly rare in Nepal's more developed trekking corridors. Our guides are certified, experienced, and know this specific route intimately — many have walked it dozens of times across multiple seasons.
