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?

Are you familiar with high-altitude illness? Do you know the symptoms? Do you know what you should and shouldn't do?

This guideline provides 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-altitude illness.

Comments, corrections and questions are welcome and may be entered at the bottom of the page.
