This is a two-fer.
First, it is ridiculously expensive to climb Mt. McKinley. Not counting personal equipment expenditures and airfare, most services come in around $6500, not to mention the 21 days of not working while on the mountain (plus buffer days for travel and rest). Between airfare, visa and passport expenses, vaccines, personal equipment, and the guide service itself, I spent significantly less on my Kilimanjaro trip.
