Are you planning to thru-hike the John Muir Trail? “America’s Most Beautiful Trail” should be on every serious backpacker’s tick list. After hiking it in a blazing (and slightly crazy) seven days, I became convinced that—while that was quite hard—the traditional itinerary of spreading the roughly 221 miles (including more than 10 miles descending Mount Whitney that’s not part of the JMT) over about three weeks has a serious flaw: With limited food-resupply options, you’ll carry a monster pack that may not only make you sore and uncomfortable, it could cause injuries that cut short your trip.
