Payoff On day 15 of my combo trek of the High Sierra and John Muir Trails, grinding up to Muir Pass, I muttered: “I hate the JMT.” My partner laughed, a wry chuckle that signaled he knew something I didn’t. Namely: A long hike wears you down before building you up, and fleeting lows are followed by endless highs. Later, basking in the alpenglow of an Evolution Basin sunset, simultaneously drained and fulfilled, I knew there was no shortcut to this moment. And I said, naturally, “I love the JMT.” —Andrew Matranga
Do it From Yosemite Valley to Mt. Whitney, every day on the 221-mile John Muir Trail delivers scenes straight from an Ansel Adams shot: granite spires and ridges reflected in thousands of alpine lakes, scores of soaring waterfalls, campsites by sparkling creeks amid meadow-and-rock havens. And because the JMT generally offers good footing and moderate grades—despite daily climbs (and descents) of 2,000 feet—with an ultralight pack you can knock off 15- to 16-mile days, pain-free. Go in late summer or early fall, when mosquito season has largely passed and you’re almost guaranteed bluebird days and mild nights. That means you can use a tarp or superlight tent, getting a big start on shedding pack weight.
Pack: Use a 3,000- to 3,500-cubic-inch pack built to carry 35 pounds. Or remove unneeded trimmings from your old workhorse. Max wt: 3 lbs.
Bag: Bring a summer down bag (rated around 32°F). Wear your clothes to sleep for extra warmth if needed. Max wt.: 1 lb. 5 oz.
Shelter: Pitch an ultralight tent or tarp (the latter with trekking poles). Two good bets: the Granite Gear White Lightning tarp or the Big Agnes Fly Creek tent (shared). Max wt: 1 lb. 12 oz.
Bear canister: Required in the High Sierra. We like the affordable BearVault BV450 and the ultralight Bearikade; the former will hold 4 days of food for one person. Max wt.: 2 lbs. 1 oz.
Inflatable mattress: Get a light pad like a Therm-a-Rest NeoAir, or a short (60-inch), insulated mat to save ounces; with the latter, put an empty pack under your feet for warmth. Max wt.: 1 lb. 4 oz.
Clothing: Pack 1 T-shirt, a long-sleeve top, shorts and pants, 3 pairs undies and socks, gloves, light puffy (like Patagonia’s Nano Puff Pullover), rainshell, sun hat, and warm hat. Max wt.: 4 lbs. 12 oz.
Accessories: Nitpick the small stuff. Opt for silnylon stuffsacks and pack cover and a 4-ounce headlamp. Carry only what you’ll need of toothpaste, sunblock, soap, etc. (buy travel sizes or put them in smaller containers). And save your knees by using poles. Max wt.: 2 lbs. 8 oz.
Food/water: Keep food to 2 pounds/day/person, and resupply at Red’s Meadow and Muir Ranch. Use a light stove like a Jetboil Flash; ship (via ground) extra fuel in your resupply box. Pack lightweight water treatment and a 3-liter reservoir; only carry as much water as needed between sources (typically about 1 liter). Max wt.: 18 lbs. 6 oz.
TOTAL PACK WEIGHT: 35 lbs.
Getting there The JMT’s northern trailhead: the Happy Isles shuttle stop in Yosemite Valley.
