Thinking of hiking the John Muir Trail? Did you know that once you're south of Donahue Pass, the average elevation of the Trail is over 10,000 feet?

Unofficial Acclimatization Guideline for the John Muir Trail provides hikers with basic information about the illnesses triggered by the reduced oxygen content of the air at higher elevations and provides recommendations for how to avoid high-elevation illness.
