Mammoth to Yosemite JMT Hike
Mammoth to Yosemite JMT Hike

Dates

This six-day segment of the John Muir Trail takes us through some of the most beautiful portions of the JMT. This hike has a little of everything, a wide river valley, a high pass crossing, great views, stunningly beautiful lakes, and jagged peaks.

This trip can be made in either direction but we like to start from Mammoth Lakes, enabling you to spend the night before the trip in Mammoth and gain some acclimatization to the elevation. We hope to get to camp in the early afternoon each day, to allow time to sit by a lake in the sun and read a book, go fishing or take an afternoon hike without the overnight pack.

Inclusions

Price includes guiding, permits, tents, kitchen gear, shuttles, breakfasts, lunches, dinners and a resupply. We will leave vehicles in Mammoth Lakes during the trip. We will take the YARTS shuttle from Yosemite Valley, back to Mammoth, at the end of the trip. Shuttle is included in your trip price and is organized by SMC. Our meals are healthy and prepared by your guide before the trip. We use good quality dehydrated ingredients to make a variety of delicious, protein-packed meals. We rarely serve pre-packaged dehydrated meals. We will resupply you in Tuolumne Meadows on day 4, so that you only have to carry 3.5 days’ worth of food from the start of the trip!

Prerequisites

Prior day hiking experience is required. No prior overnight experience is required but you need to be in good physical condition, able to walk 14 miles, and gain up to 2,000 feet daily while carrying a multi-day backpack.

Acclimatization & Physical Training

For proper acclimatization, we suggest spending at least one night at a moderate altitude, higher than 8,000 feet, just prior to the start of the journey. See our detailed tips on acclimatizing and physical training in the “Resources” tab.

Shuttle

We will leave our vehicles at Mammoth Mountain Main Lodge for the duration of the trip. On the final day, YARTS will pick you up in Yosemite Valley and bring you back to your vehicles.

Day 1

We head up the rushing San Joaquin River from Agnew Meadows along the River Trail. Shortly after Olaine Lake, we head up and pass the beautiful Shadow Lake with fantastic views of the jagged Minarets and the blocky summits of Mounts Ritter and Banner. We plan to camp above Shadow Lake, close to Shadow Creek and to make this not too long a day.

Starting elevation: 8,314 feet

Ending elevation: 9,000 feet

Distance: 4.5 miles with 1,100 feet of gain and 420 feet of loss

Day 2

We head north paralleling the San Joaquin river and pass by some of the Sierra’s most beautiful lakes all aptly named from precious gems: Ruby, Garnet, Emerald and finally to the incomparable Thousand Island Lake. We wander around the lake stopping to enjoy the scenery as we climb up and over the low and easy Island Pass. From here we descend into Rush Creek and stop near the forks of the creek to set up camp.

Starting elevation: 9,000 feet

Ending elevation: 9,650 feet

Distance: 8.o miles with 2,000 feet of gain and 1,500 feet of loss

Day 3

Today is our biggest pass but the distance to the top is not too far. So we shoulder our ever lightening packs, head over Donahue Pass and drop into Lyell Canyon. Above us rises Mt Lyell, the high point of Yosemite National Park, and we start a steady drop into the wide glacially carved valley of Lyell Canyon. We plan to camp near the Tuolumne River in the base of Lyell Canyon.

Starting elevation: 9,650 feet

Ending elevation: 8,950 feet

Distance: 8.0 miles with 1,500 feet of gain and 2,200 feet of loss

Day 4

All downhill now through Lyell Canyon until we meet our resupply in Tuolumne Meadows. As we walk, we pass the Lyell Fork of the Tuolumne River as it is lazily meandering its way to the Meadows. We take time to pick up a food resupply in Tuolumne Meadows (and maybe an ice cream at the store) before heading back out and along the JMT, climbing to camp near lovely Cathedral Lakes.

Starting elevation: 8,950 feet

Ending elevation: 9,600 feet

Distance: 13.75 miles with 1,600 feet of gain and 1,000 feet of loss

Day 5

From Cathedral Lakes we head out along the JMT and past the Sunrise High Sierra Camp. From here we drop down to our last camp in the trees of Sunrise Creek.

Starting elevation: 9,600 feet

Ending elevation: 7,175 feet

Distance: 10.5 miles with 850 feet of gain and 3,300 feet of loss

Day 6

The final day we get an early start to beat the heat and start the long descent into Yosemite Valley, taking the mist trail down past the Emerald Pool, Vernal Falls, Nevada Falls and finally to the bustle of Happy Isles and our pickup at Curry Village. After a stop at the market and store, we take the 3-hour shuttle back to Mammoth for some well earned rest.

Starting elevation: 7,175 feet

Ending elevation: 4,000 feet

Distance: 6.8 miles with 220 feet of gain and 3,400 feet of loss

Reviews

Paul, Evolution Loop Backpacking Trip

“I went on the 6-day Evolution Loop backpacking trip. I had the time of my life. The scenery was stunningly beautiful. Our guides kept us safe, prepared excellent meals, and were very knowledgeable about the area. They were friendly and kept us informed about what to expect each day. I only wish the trip lasted more days. I’ll be back for more.”

Brecken, Women’s Beginning Backpacking

“This service is great! I talked at length prior to the trip with the office staff on several different occasions. They answered all my questions and made me feel comfortable with the decision to take the trip. They were always so happy to chat at length. It was easy to book and the service was perfect!”

Colin Bogdan

Colin grew up hiking and camping via family vacations and the Boy Scouts across 15+ national parks. He still remembers the nervous exhilaration he had when his parents let him and his brothers do the exposed hike up Angels Landing in Zion National Park by themselves. When he joined the military after high school, he thought he would need to largely leave the outdoors behind. He was wrong. As part of his training, he got the opportunity to take part in two month-long NOLS courses mountaineering in Alaska and instead discovered a passion for big adventure and challenge in the mountains. After eight years on active duty and multiple deployments as a Marine Infantry Officer, Colin transitioned to reserve status in 2022 to pursue a career in mountain guiding and moved to Bishop after unintentionally falling head over heels for the Eastern Sierra during a weekend trip. He improved his skill sets as a client of fellow SMC guides Tyler Logan and Louie Allen before earning professional certification from the AMGA and NOLS to begin working as a guide/instructor in 2023. He is proud to now be in the position to call them both colleagues and also help others achieve their goals or experience the outdoors in more meaningful ways. His first love is to climb in the alpine regardless of the medium (rock, snow, or ice), though be assured, he isn’t picky and believes strongly that any day spent outside, no matter the activity or difficulty, is better than a day spent indoors.

Beyond the Eastern Sierra, he teaches three to four multi-week NOLS backpacking and rock climbing courses per year across various locations in Alaska, Wyoming, Utah, and Nevada. When not guiding/instructing anywhere, he works as the Online Sales Manager for Eastside Sports in Bishop, CA; actively serves on the Inyo County Search & Rescue team which covers missions everywhere from Death Valley to Mt Whitney; and, conducts ~6 weeks of reserve duty with the Marine Corps each year.

Allan Giernet

Allen Giernet grew up in San Diego and always had a thirst for the outdoors. Whether in the mountains, the ocean, or the desert – he had to be outside. After several years running the youth snowboard competition team at Mountain High, his longing to get into the peaks beyond the resorts took him into splitboarding. This in turn took him into the Sierras, The Rockies, The Cascades, and more. In 2010, he began teaching rock climbing as an AMGA Single Pitch Instructor in Joshua Tree and other So Cal Areas. In 2012, he founded So Cal Snow Avalanche Center, began teaching avalanche courses with the National Ski Patrol, and began to guide on splitboard. 

  He has traveled all over the west and beyond in search of great climbing and big snow covered mountains to find powder filled descents. But the magical Eastern Sierra will always hold a special place in his heart. 

  Allen currently calls Methow, Washington home in the North Cascades and still spends time in So Cal. He ski guides and teaches avalanche courses in The Eastern Sierra, Colorado, and the North Cascades. That thirst for the outdoors remains unquenched and Allen loves to share this enthusiasm with anyone and everyone out there. When not out in the mountains searching for the next descent, hiking, biking or paddling, he may be found running The Methow Store with his partner in the Methow Valley. Serving up cold beer and great food next to the best put in on the Methow River.

Ian McEleney

An enthusiasm for backpacking was Ian’s gateway into the mountains and soon led to a love of climbing. After cutting his teeth on the rock and ice crags of New England he traveled all over the country making ascents of everything from short roadside rock climbs to big peaks in remote areas. Over a decade ago he discovered that the Eastern Sierra hold a magical mix of amazing mountains and climbing, easy access, and good weather. Now this place is home for him and his family.

Though he loves all kinds of climbing, big walls and winter routes hold a special place in Ian’s heart. He rounds out the year with forays to Alaska, Red Rocks, Joshua Tree, Moab, the North Cascades, and Canada.

Mike Mourar

Mike is originally from Pennsylvania where he learned to ski on the icy mountains of the Northeast. He moved to Northern California soon after high school and received degrees in Outdoor Adventure Education from Feather River College and later Southern Oregon university. He has worked in outdoor education for over 15 years, leading wilderness education expeditions all across the world and the American west. Mike currently ski guides and teaches avalanche education courses in the Sierra Nevada Mountains. He loves to ski steep narrow couloirs on warm sunny days in the Sierras! When not guiding on skis, Mike can be found kayaking the rivers in the Pacific Northwest. 

Heather Shaw

Heather grew up in the Bay Area and has many fond memories of backpacking and camping in the Sierra as a kid. She moved up to Oregon to attend Lewis & Clark College and obtained a degree in Environmental Studies focusing on education and food systems. While living up in Oregon Heather fell in love with the Cascades and began guiding her peers on backpacking trips, cross-country skiing and even local mushroom foregoing. Following her passion for guiding and the outdoors she spent the summers guiding children on backpacking trips and adults in sea kayaking. Heather enjoyed living in the Portland area, skiing on Mount Hood and doing lots of cycling but eventually she decided it was time to come back to sunny California. For the past couple of years she has been spending summers and fall in California guiding students in backpacking, river trips and day hikes. She is excited about guiding backpacking trips in the Eastern Sierra this summer. Heather is a Wilderness First Responder and Leave No Trace Trainer.

Robert "SP" Parker

Robert “SP” Parker, hails from the picturesque landscapes of New Zealand. His journey into the realm of mountaineering began during his days at the University of Auckland, where he delved into the world of climbing alongside the university tramping club (akin to “backpacking” for our American counterparts).

He relocated to Yosemite Valley in 1979. He traveled the US climbing in all the great places: Yosemite, Tuolumne, Colorado, Joshua Tree, Devils Tower, Canada. In 1996, he joined forces with Todd Vogel to found Sierra Mountain Center. SP has over 40 years of full-time professional mountain guiding experience. He has earned IFMGA certification in Rock, Ski, and Alpine disciplines and has served as a past director of the AMGA.

As the torch of ownership at SMC passes into the capable hands of Emma, his passion for guiding in the breathtaking Sierra region continues to burn bright, and he eagerly supports Emma in her new role.

Larry Gumina

Larry is a native of the New Jersey shore. Raised as an ocean lover, Larry spent his early days surfing and being in the water as much as he could. Through an active involvement in scouting, as well as an adventurous friend group, Larry found a passion for the mountains. Naturally, this passion had him trade his surfboard for a snowboard, and he went west! Larry graduated from the University of Colorado Boulder with degrees in Environmental Studies as well as Atmospheric and Oceanic Circulation. In Colorado, he fell more in love with the mountains. After graduating, Larry moved to Alaska to explore the wilderness of the last frontier through backpack and canoe guiding. When COVID struck and found Larry abroad in Central America, he came back to the states hoping to get back to Alaska, but discovered the Sierra along the way. And the high peaks and the fairer climate of California was as far as he made it. Larry now resides here in Bishop, where he spends his time exploring the mountains via roped climbing, splitboarding, and hiking. When not guiding, Larry enjoys traveling and climbing the high, glaciated peaks of Central and South America. Larry’s favorite trip to lead in the Sierra is the Bishop to Mammoth backpack as the variety of the terrain offers tremendous opportunities for natural and human history studies! Larry holds a certification as a Wilderness First Responder, a Leave No Trace Trainer, and a AIARE Level I.

Louie Allen

Louie began guiding with Sierra Mountain Center in 2015 after falling in love with the people and places of Bishop, CA, and the Sierra Nevada mountains.  He grew up climbing and backpacking in the southeastern US and moved West to pursue bigger mountainous terrain.  He is a passionate and dedicated climber in all of its forms and has backpacked extensively across the Sierra.  It is a joy for him to share his favorite peaks and trails with visitors.  Louie is an equal-opportunity cookie lover and die-hard Cincinnati Bengals football fan.  He travels to the eastern US often in order to pursue world-class rock and ice climbs, but always finds his way back to the Sierra.

Louie is an AMGA Certified Rock Guide and is pursuing Alpine Guide certification.  He holds an MS in Recreation and Sport Sciences and a Graduate Certificate in Sport Coaching.  He works as a guide, strength trainer, and climbing coach to help developing climbers and hikers achieve meaningful goals in the mountains.

Anouk Erni

Anouk grew up on the glaciers and peaks of Switzerland where her family is from and currently resides. Anouk has had an appreciation for the elevated outdoors from an early age. She has lived in Europe, America’s east coast, and finally, she came to the west coast in her teens, and never left. Even though she calls the Eastern Sierra her home, she began her guiding career in the Pacific Northwest, where she worked on glaciated peaks such as Mt Rainier and Mt Baker, and rock guided during the summers. However, having learned to rock climb in California and frequenting the Eastern Sierra during her years living in Los Angeles, she ultimately returned to California eight years ago and has been guiding here year round. In the summers, Anouk guides rock and alpine trips, and during the winter seasons, she ski guides and teaches avalanche courses. She sees her guide work as a way to increase and infuse passion and knowledge into the outdoor community – her way of giving back after having been fortunate enough to receive solid mentorship during her initial years climbing in California.

 

Anouk is an AMGA Certified Rock Guide, Apprentice Ski Guide, and Apprentice Alpine Guide, as well as an AIARE avalanche course leader and AAI course leader.

Dave Stimson

Dave is originally from Alberta, Canada, but has traded in his Canadian passport for his American one, lured by clean Sierra granite and perfect California weather. He graduated from Mount Royal University in 2007 with an undergrad in Ecotourism & Outdoor Leadership and has been working ever since as a ski patroller and avalanche forecaster in Canada during the winters. Dave has been climbing since 2003 and has climbed in Squamish, the Canadian Rockies, The Bugaboos, the Tetons, Red Rock, Indian Creek and Peru, to name a few destinations. His first time climbing in California was in 2103 in Yosemite Valley and was instantly in love. He has been with the SMC team since 2015 and is excited to continue climbing and guiding in the Range of Light. 

Dave holds a Wilderness First Responder certification, and a Canadian Avalanche Association Level 2. He began the AMGA program in 2014 and has become a fully certified IFMGA Mountain Guide.

Emma Gasman

Emma joined the Sierra Mountain Center team in early 2021 as the Program Director.
