The John Muir Trail is a 340 km (211-mile) backcountry route from Yosemite Valley to the summit of Mount Whitney at 4,421 m — the highest peak in the contiguous United States. Most thru-hikers complete it in 21 to 28 days; section hikers can tackle individual legs in 3 to 6 days without competing for a full permit.
What Makes the John Muir Trail the Premier American Wilderness Route
Running through three national parks — Yosemite, Kings Canyon and Sequoia — the JMT stays above 2,400 m for most of its length. That altitude means six major passes above 3,600 m, including Forester Pass at 4,009 m (13,153 ft), the highest maintained trail pass in the Sierra Nevada. Unlike the Appalachian Trail, the JMT has no trail towns, no hostels and very limited resupply — isolation is a core part of the experience.
The trail gains and loses roughly 20,000 m of cumulative elevation over 340 km. A strong hiker averaging 20 km per day completes it in three weeks; 15 km per day is more realistic when carrying a full bear canister and 7 days of food. As of 2026, the PCTA reports historically low Sierra snowpack in several zones, meaning most passes open earlier than usual — some accessible from late May.
John Muir Trail Permits: How to Secure One in 2026
The permit system is competitive. Permits are administered through Recreation.gov and open in a lottery 168 days before the target start date. The Happy Isles trailhead in Yosemite Valley — the most popular entry point — fills within minutes. Two strategies improve your odds:
- Enter the lottery for shoulder-season dates (late September or early October). Mosquitoes are gone, crowds thin dramatically and passes are still snow-free.
- Choose an alternative trailhead: Lyell Canyon, Tuolumne Meadows or Red Meadow all have easier permits and still deliver the core JMT experience for section hikers.
If you thru-hike south to Mt Whitney, you need a separate Whitney Zone permit for the final 22 km. This permit also runs through Recreation.gov and sells out months in advance — book it at the same time as your main JMT permit.
The Six Major Passes: What to Expect
Each of the JMT's six major passes presents different terrain and scenery. Here is a quick reference for planning your daily mileage around the passes:
| Pass | Elevation | Difficulty | Notes |
|---|---|---|---|
| Donahue Pass | 3,810 m | Moderate | First major pass south of Tuolumne Meadows |
| Silver Pass | 3,534 m | Moderate | Snowfield possible into early July |
| Mather Pass | 3,871 m | Challenging | Steep south face; microspike assessment needed in early season |
| Pinchot Pass | 3,841 m | Moderate | Long approach through Kings Canyon |
| Glen Pass | 3,625 m | Challenging | Rock scramble on north face descent |
| Forester Pass | 4,009 m | Strenuous | Highest point; can hold snow through late July in normal years |
What to Pack for a JMT Thru-Hike
Bear canisters are legally required for all overnight travel on the JMT. The Garcia BV500 and Bearikade are the two approved models that dominate the trail. Beyond the canister, shelter selection shapes your pack weight more than any other item on a 3-week route.
For a pack that handles 10 to 12 kg of starting food weight without destroying your hips, the Hyperlite Mountain Gear Unbound 55 at 780 g strikes the best balance of weight and structure available in 2026. Section hikers carrying 4 to 5 days of food will find the REI Flash 55 equally capable at a significantly lower price. For the sleeping system, a bag rated to -7°C covers Sierra summer nights — the Enlightened Equipment Enigma 20°F at 481 g is one of the lightest options at that temperature rating. Footwear-wise, the Hoka Anacapa 2 GTX Low handles Sierra granite and creek crossings while offering enough cushion for back-to-back 25 km days.
Cell service is essentially non-existent across 90% of the JMT. A Garmin inReach Mini 2 is the only reliable way to call for rescue in the Kings Canyon backcountry — carry one, full stop. For gear-list planning targeting sub-2 kg base weight, see the ultralight 2 kg backpacking kit guide.
When Is the Best Time to Hike the John Muir Trail?
The JMT is typically accessible from mid-July through late September. In 2026, low Sierra snowpack makes Forester Pass hikeable from late June without additional traction devices — verify current conditions with the Inyo National Forest before departure. Peak crowds fall between mid-July and mid-August; late August and September offer stable weather, fewer campsite competitors and exceptional autumn light on the granite.
Temperatures above 3,000 m drop to 0°C or below on most summer nights. Afternoon thunderstorms build over the Sierra crest from around 1pm most days — plan to cross exposed passes before noon.
Resupply Strategy for the John Muir Trail
Most thru-hikers send boxes to Tuolumne Meadows (post restante), Vermilion Valley Resort (ferry required), Muir Trail Ranch (fee-based, reservation essential — spaces sell out in January 2026) and Onion Valley trailhead near the Whitney section. Red Meadow is a practical option for a hot meal around the midpoint. For managing the calorie density of your resupply boxes, the backpacking food weight guide provides specific recommendations — the JMT food carry is one of the most demanding in North America, requiring 700 to 800 kcal per day more than typical 3-day trips. For high-density options suited to long carry sections, see the high-calorie backpacking food guide 2026.
Frequently Asked Questions
How hard is the John Muir Trail for an average hiker?
The JMT is a strenuous multi-week route requiring solid backpacking experience and good fitness. Average daily elevation gain is 600 to 900 m, and altitude affects most people above 3,000 m. The first week is hardest as legs and lungs adapt to sustained mountain terrain. Completing a 4 to 5-day section hike is an excellent way to gauge readiness before committing to the full trail.
Do I need a bear canister on the John Muir Trail?
Yes — bear canisters are legally required for all overnight stays on the JMT. Rangers issue fines for non-compliance. The Garcia BV500 fits approximately 6 days of food for an average-sized hiker eating 700 g per day. The Bearikade Weekender fits 5 days and weighs 200 g less than the BV500.
Can I section-hike the JMT without a full thru-hike permit?
Yes. Entry points other than Happy Isles in Yosemite Valley have easier-to-obtain permits through the Inyo National Forest quota system. Many hikers complete 5 to 8-day sections in Kings Canyon or the Whitney Zone with far less permit competition than the Yosemite start.
What is the permit quota for the Happy Isles JMT trailhead?
The daily quota for Happy Isles is 45 permits per day on the JMT route. Approximately 60% are released in the advance lottery 168 days before the start date; 40% are available as walk-up permits at 11am the day before. The lottery is the more reliable method for peak summer dates.
What footwear do most JMT hikers choose in 2026?
Trail runners now outnumber traditional boots on the JMT. The Hoka Speedgoat 7 and Altra Lone Peak 9 appear on most 2026 gear lists. Waterproof versions add meaningful value given Sierra afternoon showers and creek crossings earlier in the season when snowmelt is high.
