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 (plus more than 10 miles descending Mount Whitney) 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.
