A basic permit costs $8,000 on the Tibetan side, and $10,000 on the Nepalese. From there, independent expeditions—no guides or sherpas—can stay as low as $30K. But the vast majority of today’s mountaineers use sherpas as porters and guides, as well as western expedition guides, which can hike the price up to $65K. For larger groups, the bill can run as high as $100K. And, yes, these numbers are all per person.
