Hiking Mt. Whitney is on the adventure bucket list for many outdoor enthusiasts. With an elevation of 14,508 feet, Mt. Whitney is the tallest mountain in the 48 contiguous US states.
Mt. Whitney is a part of the Sierra Nevada Mountains, and its trail starts in the Inyo National Forest and enters Sequoia National Park. The summit is also the southern end of the John Muir Trail, โJMT.โ Climbing to the summit and back can be done in a day trip or an overnight backpacking trip. Permits are needed for this hike from May 1st to November 1st each year. You can apply for a permit during the Mt. Whitney Lottery between February 1st and March 15th. Lottery results will be available on March 24th.
Lottery application
Applying for Mt. Whitney permits is the easy part. You and your group will first need to decide if you would like to apply for a day-use permit or an overnight permit. Only 100 day-hikers and 60 backpackers are permitted each day.
Please see the Forest Service site for more information on the Lottery Application Statistics.ย
With the overnight permit, you will need to select an exit date. Take into consideration your groupโs size, physical capabilities, and speed. Donโt forget to take into account the total trail length of 22 miles and the elevation gain of 6,100 feet, along with your groupโs experience with backpacking.
Thereโs only one option for the start point which is the Whitney Portal, โMt Whitney Trail JM35โ and youโll have to select your exit point. Most people who are doing the day-use or a one-night, overnight permit select โMt Whitney Trail JM35โ as the exit as well. This means you are returning to the same point of entrance, where you likely parked your car. I have no experience exiting any other way so I can’t shed any light on that.
If youโre selecting an overnight permit you will need to input your โtrip itinerary.โ This is where you plan to camp for the night. The main campsites in the Whitney Zone are Outpost Camp and Trail Camp. If youโre doing a one-night permit I recommend starting no later than noon (the earlier you start, the better so that you can reach your camp before sundown) and setting up camp at Trail Camp. This is the closest campsite to the summit and is 6.3 miles from the Whitney Portal. This is where myself and my group stayed the night during our one-night trip. We then woke up before sunrise the following day to summit Whitney. We also left our gear and only took a daypack to the summit. We finally reached the Whitney Portal around 7 pm. It was already dark since we did this in October so going during the summer is preferred since you have more sunlight and the weather isn’t so cold. We also had some snow which would have been avoided if we had a permit for the summer.
If youโre doing a two-night trip you can camp at Outpost Camp as well. Outpost Camp is 3.8 miles in from the Whitney Portal. If you need some extra time getting acclimated to the elevation staying at Outpost Camp may be worth the extra night.
Trail Overview
Although the area has plenty of trees the first few miles of the trail are very exposed. It can get rather hot during the day so itโs best to start hiking as early as you can. Those who do the hike in a single day usually start between midnight and 3 am. If youโre doing an overnight trip, starting around 10 am should get the average hiker to Trail Camp before sundown.
After entering the โWhitney Zoneโ itโs only about another mile until youโre at Outpost Camp. Itโs a lot more woodsy and scenic in this area. Soon after youโll pass Mirror Lake. As youโre climbing on and up youโll be above Mirror Lake. The view from here is beautiful. Enjoy it because the next two miles to Trail Camp can be gruesome. Youโll be climbing on uneven rocks until you finally hit Trail Camp (where you might be sleeping on some rocks).
As youโre leaving Trail Camp youโll go up the infamous 99 switchbacks. If youโre not a fan of switchbacks these can be tough. After youโve completed the switchbacks you will have reached Trail Crest. With only three miles to the summit, youโll be surrounded by amazing views overlooking some lakes. Continue on the narrow trail, watch your footing and keep heading towards the summit. Youโll see the hut in the distance and just outside the hut is the summit register where you can sign your name. The summit registers are maintained by volunteers through the Sierra Club. Archives are kept at the Bancroft Library at UC Berkeley and a collection of registers can also be found at the UCLA Library. Donโt forget to take your summit photo and if you need some shelter for a few minutes go inside the hut.

Water Sources
There are lakes along the Whitney trail where you can get water. Youโll need to filter this water. There are various lakes and streams between Whitney Portal and Outpost Camp. As your passing Outpost Camp, youโll see Mirror Lake. This is the last lake along the trail before Consultation Lake which is less than a half mile from Trail Camp. The lake at Trail Camp is the last reliable water source, so itโs smart to fill up here before continuing on. And I would recommend topping off on your way back down.
I carried five liters of water when I began my hike and ran out when I reached Trail Camp. I only filtered water at this source before summiting and again after summiting. I when I left Trail Camp and began hiking the 99 switchbacks my hydration bladder tube had froze up. I had to stop and drink straight from the bladder and put the water back into my pack. If youโre going during a cold month itโs recommended you have an insulation sleeve for your tube. My friend had one and her water was fine. Luckily we were able to share water from her hydration bladder so I didn’t have to keep stopping to take mine out.
Preparing For Mt. Whitney
Preparing for Mt. Whitney is somewhat like preparing for a marathon. You don’t need to hike similar mountains in order to prepare but you should be gradually challenging yourself more and more.
Find out what you need to work on. For some, the elevation gain isย the thing they need to work on. For others, it’s the distance. If you know the switchbacks will be a challenge, work steeper inclines into your hikes and stairs into your workout.
Time is a challenge for me. I can do the distance but I get tired and restless during long hikes. After six hours I just want a nap and I get hungry quickly. Some say I get “hangry.” I know this is true so I prepare by packing foods I like that will keep me happy. I also take energy chews to try to keep my energy up.ย
Knowing your body and what challenges you are important. I know my body well and know that I need to get great sleep before doing big hikes like Mt. Whitney. If you can prepare for what’s ahead of you then you’re one step closer to reaching the summit successfully.ย
Iโm by no means an expert when it comes to health and/or personal fitness. You should always consult with a doctor if you have any concerns about your body and health. Altitude sickness is real and it isnโt fun to deal with. If youโre concerned about the altitude, speak with your physician.

โข Backpacking tent (needed if doing an overnight trip)
1-person tent
2-person backpacking tent
I personally love Marmot tents. If you’re more comfortable sleeping on your own I suggest getting a 1-person tent, but if you hike in groups and preferย a tent-mate then get a 2-person tent. It’ll weigh a little more but you and your tent-mate can split the weight.
โข Sleeping bag (needed if doing an overnight trip)
โข Sleeping pad (needed if doing an overnight trip, the ground at Trail Camp is rocky)
โข Trekking poles
โข Portable stove and cooking bot or Jet Boil
โข Propane canister
โข Lighter/matches
โข Utensil
โข Water filter
Sawyer is one of the more compact water filtering systems. It takes some time to filter the water but it’s lightweight and compact.
If you’re camping with a group consider the Platypus GravityWorks. It’s easy to use and can filter water quickly and with less effort.
โข Solar-powered lantern
โข Headlamp
Black Diamond is a reputable brand and this one emits 300 lumens (thatโs BRIGHT!!)
โข Water bladder (3-liter bladder is recommended)
Platypus is a great brand and their bladders are the easiest to clean!
โข Water bottle (youโll want a water bottle for your cooking water and/or to drop your electrolyte tablets in)
I love Hydro Flask because my water will stay cold or hot for hours and that makes a huge difference when it’s super hot or cold outside.
โข Travel sized toiletries (skip anything you can do without)
โข Toilet paper
โข Sunscreen
โข Lip balm
โข Small first aid kit
โข Moleskin to prevent blisters
โข Hand warmers and/or feet warmers (good for cold morning and cold nights)
If you get cold easily, pack some hand warmers. I keep these in my pockets in the morning when itโs cold and in my sleeping bag at night. Youโre not supposed to keep them in your sleeping bag but itโs always done the trick for me. The brand I use is Grabber.
โข Daypack
โข Extra large ZipLock bags (you need to carry-out your trash so bring at least 1)
โข WAG bag (for human waste. You will be given one bag when you pick up your permit)
โข Bear canister (can be rented where you pick up your permit)
โข GPS/Beacon to track location in case of an emergency
These can be pricey but worth the investment if you’re doing more dangerous hikes or hiking unmarked trails.
Clothing:
โข Hat/cap for sun protection
โข Sunglasses
โข Beanie (for higher elevation and to wear at night/morning)
โข Neck gaiter
โข Dryfit top (bring layers as it gets colder in higher elevation)
โข Hiking pants/athletic pants
โข Dryfit base layer
I swear by this one because of itโs โomni-heatโ technology. It reflects your body heat which helps to keep you warm.
โข Dryfit undergarments
โข Fleece jacket
โข Down jacket
โข Hiking boots
This is the boot that I used n the trail and I still use today (three years later). Theyโre a bit more expensive than the average boot but I had never had a blister and theyโve been the most comfortable boot for me.ย
โข Wool socks
โข Fleece gloves (for higher elevation and to wear at night/morning)
โข Waterproof insulated gloves (recommended for colder months)
Note: Avoid cotton clothing as cotton traps moisture. Being damp and cold isnโt a good combination.
Food:
โข Oatmeal
โข MREs (Meal, ready to eat): popular brands such as Mountain House and Backpackerโs Pantry are available at your local outdoor equipment store and online
โข Bar: Clif, Larabar and Kind bars are my favorites
โข Trail Mix
โข Dried fruit
