Intro
What to pack for the John Muir Trail comes down to three unforgiving conditions: cold nights above 10,000 feet, water that needs treating everywhere you find it, and a bear canister that’s mandatory for the whole route. Picture the version of this trip that goes right: sunrise over Thousand Island Lake, the granite still pink, your legs tired in the good way, three weeks of trail behind and ahead of you. That’s what 211 miles and eight passes over 10,000 feet buys you. What it costs is a kit that has to work for weeks without a resupply run to fix a bad call.
The John Muir Trail doesn’t forgive a kit built around what’s already in the cupboard. A third of the route sits above 10,000 feet, nights up there drop below freezing even in August, water is everywhere but every drop needs treating, and a bear canister is a legal requirement for the entire way, no exceptions. This list is built against those three conditions first, everything else second.
Still deciding whether to walk it? Start with the full John Muir Trail guide for permits, route and logistics. For the gear philosophy behind every pick below, our multi-day hiking gear guide covers the fundamentals.
Conditions That Drive Your Kit
- Distance and days: 211 miles, typically 14 to 21 days.
- Season: mid-July through September. Cold nights at altitude in any month; afternoon thunderstorms build over the passes from mid-July into August.
- Terrain: sustained high alpine trail, roughly a third of the route above 10,000 feet, with regular stream crossings.
- Remoteness and resupply: five common resupply points (Tuolumne Meadows, Red’s Meadow, Vermilion Valley Resort, Muir Trail Ranch, Independence via Kearsarge Pass), several days apart. No towns directly on trail.
- Wildlife: black bears active along the northern half.

How This Kit Is Built
Everything here earns its place against the three things the JMT throws hardest at you: mandatory bear-proof food storage, cold nights at altitude for weeks running, and near-constant water crossings that all need treating. The picks below are built from the official Yosemite and Inyo National Forest permit requirements, cross-checked against gear-authority testing (CleverHiker, OutdoorGearLab) and the consensus kit experienced JMT thru-hikers actually carry, not just what happens to be in stock.
The Kit, by Category
Bear canister (critical)
Not optional. Every ounce of food, toiletries and scented items must go in an approved canister for the entire route, checked at permit stations and occasionally on trail. Get this wrong and you either get turned back at the trailhead or risk a genuinely serious wildlife problem.
Our pick: BearVault BV500. The volume most JMT thru-hikers land on for a 5 to 7 day food carry between resupplies, clear polycarbonate body so you can see what’s left without opening it, and it doubles as a camp stool. See our bear canisters guide for how it compares against the rest of the field.
Renting instead: Yosemite rents canisters at any wilderness permit station for the length of your trip, a sensible call if the JMT is a one-off rather than the first of many Sierra trips.
Sleep system (critical)
Nights above 10,000 feet drop below freezing even at the height of summer, and you’ll spend a third of the trail up there. Undercook this and you’re not sleeping for three weeks.
- Sleeping bag or quilt: a 20°F-rated down bag is the trail-standard choice, warm enough for the cold camps at altitude without the bulk of a true winter bag. Compare options in our down sleeping bags guide if you run warm, or our synthetic sleeping bags guide if you want a bag that still insulates when damp, a real risk on a three-week trip with regular creek crossings.
- Sleeping pad: you need real ground insulation, not just cushioning. Look for an R-value of 3 or higher. Our best insulated sleeping pads for hiking guide covers the genuine R-value picks for this trail, including the Therm-a-Rest NeoAir XLite NXT (R-value 4.5). For the JMT specifically, prioritise the R-value spec over anything else on the label.
Footwear (critical)
211 miles is a lot of trail to get wrong underfoot, and you’re carrying a loaded pack with a bear canister the whole way.
- Trail runners: increasingly the default choice among JMT thru-hikers, lighter over long mileage and they dry fast after a ford. Our breathable hiking shoes guide covers picks suited to this kind of daily mileage.
- Boots: still the right call if you’re carrying a heavier pack or prefer ankle support on scree and pass descents. See our durable hiking shoes guide for options built to hold up over three weeks rather than three days.
Whichever you choose, break them in properly before you go. There is no shortcut for that on a trail this long.
Water treatment (critical)
Water is genuinely everywhere on the JMT, which is exactly why you’ll be filtering constantly rather than occasionally.
Our pick: a squeeze-style filter rated for protozoa and bacteria, fast enough to keep up with frequent refills and light enough that the weight doesn’t matter over three weeks. See our water filters for hiking guide for picks built for this kind of daily volume. Carry chemical treatment tablets as backup in case your filter clogs or freezes overnight at altitude.
Pack
You’re carrying a bear canister, up to a week of food and a full sleep system between resupplies. Most JMT hikers land in the 55 to 65 litre range. Our multi-day backpacks guide covers that range well; if you’re chasing a lighter base weight, our ultralight backpacks guide is the place to look instead, just check the pack’s stated capacity actually fits a bear canister before you buy.
Shelter
Afternoon thunderstorms build over the high passes from mid-July on, so a genuinely weatherproof shelter matters more here than on a fair-weather trail. A freestanding tent is the safer default given how often you’ll be pitching on rock or sandy ground where stakes don’t always hold. Compare options in our freestanding tents guide.
Rain and wind protection
Storms on an exposed pass are a genuinely different problem to storms in a valley campsite. A proper waterproof shell, not just wind resistant, is worth the weight. See our lightweight hiking jackets guide.
Insulating layer
Camp temperatures at altitude call for a warm layer beyond your sleep system, for the hour between arriving at camp and getting into your bag. A mid-weight synthetic or down insulated jacket from an established outdoor brand covers this: look for baffled construction and a stated fill weight, a better guide to real warmth than a marketing temperature rating. Our multi-day hiking gear guide covers how insulated jackets fit into a wider layering system if you’re still working out your setup.
Sun protection
A third of this trail is above treeline with no shade and thin air, real UV exposure for weeks at a stretch. A wide-brim sun hat and a proper sunshirt matter more here than on most trails on this site. Look for a hat with a UPF rating and a chin strap that survives wind on the passes, and a sunshirt in a light synthetic you can hike in without overheating.
Bug protection
Mosquitoes and black flies are genuinely bad in July and August, worst between Tuolumne Meadows and Edison Lake and through the Rush Creek drainage. By September most bugs have gone. A permethrin treatment on clothing plus a DEET or picaridin repellent for skin is the standard combination. Our bug nets for camping guide covers camp protection, though its current top pick is a pop-up screen shelter rather than a wearable head net, worth knowing if you want on-trail protection during a bad bug stretch.
Navigation and safety
A GPS app with an offline JMT track is the practical baseline; paper maps as backup. Given how remote the middle third of this trail runs, through Kings Canyon with no phone signal and days between resupply points, a personal locator beacon or satellite messenger is worth carrying even though it’s not something we sell through an affiliate link. This is a genuine safety item, buy or hire one directly.
Camp kitchen
Fires are prohibited above 10,000 feet along most of the route, so plan around a stove regardless of season. A compact canister stove covers this trail well. Buy fuel canisters locally in Yosemite Valley, Mammoth Lakes or Bishop rather than trying to ship or fly with them; they can’t travel by mail or air.
Trekking poles
Genuinely useful here, both for the sustained climbing and descending over eight passes and for the creek crossings, some of which run fast in early season. See our trekking poles guide.

What You Can Skip
A second pair of full shoes. Camp shoes matter (your feet will want out of trail shoes by evening), but a lightweight sandal or foam clog does the job. You don’t need a backup pair of hiking shoes.
Cotton anything. Obvious to experienced hikers, worth saying anyway: cotton takes forever to dry after a creek crossing or an afternoon storm and offers no insulation wet. Every layer should be synthetic or wool.
A full-size stove and cookset for solo hikers. People consistently overpack cooking gear for a trip this long. A single pot and a compact canister stove covers breakfast, dinner and coffee for one or two people; you don’t need a full cookware set out here.
Heavy binoculars or a big camera setup. The scenery does the work. A phone camera covers most of what people actually want to remember from this trail; extra glass adds weight you’ll feel on pass number six.
Renting vs Buying
The one item worth genuinely considering as a rental is the bear canister: Yosemite rents them at wilderness permit stations for the cost of your trip, which makes sense if this is a one-off. Everything else on this list, you’ll get more use out of owning if you plan more than one Sierra trip, given how specific the sleep system and footwear picks are to this kind of high-altitude, multi-week terrain.
Final Thoughts
The JMT punishes a kit that hasn’t been thought through and rewards one that has. Get the bear canister, sleep system and water treatment right and the rest of what to pack for the John Muir Trail is standard multi-day gear you likely already understand. For the full trail context this kit is built around, permits included, see the John Muir Trail guide. For the gear fundamentals behind every category here, start with our multi-day hiking gear guide. If you’re building out a Sierra kit more broadly, our Larapinta Trail packing list shows the same category-by-category approach applied to a very different, hot and dry climate, useful for seeing how the method adapts.
Frequently Asked Questions
Do I really need a bear canister for the whole John Muir Trail?
Yes, for the entire route through Yosemite, Sequoia and Kings Canyon, with no exceptions for thru-hikers. Rangers do check at permit stations and sometimes on trail. If you don’t want to buy one, Yosemite rents them at any wilderness permit station.
Can I rent gear near the trailhead?
Bear canister rental is the main one, available directly through Yosemite’s permit stations. Beyond that, outdoor shops in Mammoth Lakes and Bishop carry general backpacking gear rental, but don’t count on renting a full kit at short notice in peak season.
What’s the one thing people forget on the John Muir Trail?
A genuine backup water treatment method. Filters clog or freeze, and you’re days from a resupply point when it happens. Chemical tablets weigh almost nothing and solve the problem completely.
How heavy should my pack be?
Most JMT thru-hikers land somewhere between 25 and 35 lbs including a full bear canister and several days of food. Base weight (everything except food, water and fuel) in the 15 to 20 lb range is a realistic target without going ultralight-extreme.
