How Long Will It Actually Take Me To Complete The John Muir Trail?

While expert hikers typically complete the trail in 2-3 weeks, this incredible stamina is determined by a hiker’s fitness, experience in navigating rugged terrains, and logistic planning skills to secure provisions for the duration of this lengthy trial.

It’s important to note that although the trail officially ends at the Mt Whitney summit after 210 miles, hikers must also descend to the Whitney Portal, which results in a jaw-dropping 221-mile trail from end-to-end.

Even though it is possible to complete the trail in approximately two weeks, the High Sierra terrain is incredibly challenging to navigate with its staggering elevation gains. Thus, most hikers will add a few rest days (zero days) to enjoy the trail leisurely.

Although it must be said that François D’Haene holds the record for completing the trail in less than three days, which is simply mind-boggling!

While the trail is well signed and maintained and typically easy to navigate, it is always advisable to have a compass and topographical map.

What Should I Do To Prepare For The Epic JMT?

If you think that merely exercising for a month in preparation for this demanding trail with 80,000 feet elevation variations is enough, think again!

If you are not at a peak fitness level, it can quickly turn into a nightmarish “death march” of sorts. So, up the ante with your exercise routine by including weight training and cardio to improve your lungs, including core and leg strengthening workouts at least 16 weeks before departure.

Scrutinize JMT map packs and guidebooks to compile a detailed hiking schedule that will break this intimidatingly long trail into small, doable segments which are aligned to your fitness levels and expertise.

If you tend to suffer from altitude sickness, it would be advisable to transverse the trail from north to south. Then, your body will steadily get used to the elevated terrain, and you will be able to experience the best part of the trail towards the end.

The only disadvantage is that there’s a dramatic elevation gain in the Yosemite Valley, which might result in bouts of altitude sickness.

Most importantly, courier some food supplies to the various stations you will encounter along the route at least three weeks in advance to simply focus on nature’s bounty without worrying about dwindling supplies.

Your chance of completing the trail is also determined by the weight you can carry in your backpack. If its contents are too heavy, it will affect your balance, burn more energy than you’re consuming, and result in pesky backpack strap pain, which can all be avoided with proper planning.

The Ideal Times To Hike The John Muir Trail

The most suitable time for less experienced hikers is between June and September, when most of the snow has melted.

However, experienced hikers might prefer the challenge of overcoming snow-peaked mountains during the October months.

You can either park your vehicle in the Yosemite or Whitney Portal long-term parking areas or take a shuttle from any of the following airports Reno, San Francisco, Las Vegas, Oakland, Fresno, or Sacramento, to access the trailhead.

JMT Permit Applications

You will need to apply for a Yosemite Wilderness permit at least 24 weeks in advance when they are issued on a lottery basis. However, permits are obtainable on a first-come, first-serve basis 3-7 days before departure (if you are lucky enough).

It is imperative to allow for some zero days when applying for a permit as you will not be permitted to complete the trail with an expired permit – rather, play it safe!

Although permits are compulsory and strict quotas are imposed during the winter months, you don’t need to make a reservation ahead of time. Instead, simply collect a permit at the park’s entrance or obtain one via self-registration.

Your Essential Backpacking Kit

A key success factor in completing the JMT is to carry a light backpack that caters to your needs.

Your backpack kit should be as light as possible, so aim for a maximum backpack weight of about 20 pounds and contain all the essential items you will need to navigate the trail successfully.

Apart from your crucial hiking poles, you will need a makeshift shelter and tent, a pack cover, bear canister, electronic chargers and batteries, water bottles and filters, a raincoat, gloves, a cooking set, toiletries, headlamp, compass, maps, first aid kit, fire starters, GPS, clothing, and food.

Although the trail weather conditions are predominantly mild, it can be hot at times, so pack sun protective gear like caps, sunscreen, long sleeve shirts, and sturdy protective eyewear.

Fortunately, there are national park stations dotted along the way where you can stock up on essential supplies at Mammoth Lakes, Tuolumne Meadows, Kearsarge Pass, Lake Edison, and various other locations.

Essential Safety Measures On The John Muir Trail

There are numerous black bears on the trail in the Lassen Volcanic National Park and between the Kennedy Meadows and the Sonora Pass, so you will need to use bear canisters to safely store your scented goods and food items.

While it would depend on the season, you might have to cross treacherous rivers that can be incredibly dangerous to navigate, so familiarize yourself with best practices before safely crossing rivers along the trail.
