Trip Overview

The Trip

Bask in the glorious light of mid-summer on our eight-day 50-mile loop into southern Yosemite. Beginning our trek in Tuolumne Meadows, we hike up and over Vogelsang Pass as we spend our first two nights at pristine alpine lakes. The High Trail, with its panaromas of the Clark Range, then leads us to the headwaters of the Merced River. Layover time there lets us explore the meadows in the shadow of Mt Lyell and climb the park's southern passes, with their stunning views of the Minarets. We will then hike down into the deep Merced River canyon and back up along the rushing cascades of Fletcher Creek in our return to Tuolumne Meadows.

"Walk away quietly in any direction and taste the freedom of the mountaineer. Camp out among the grasses and gentians of glacial meadows, in craggy garden nooks full of nature's darlings. Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you and the storms their energy, while cares will drop off like autumn leaves." - John Muir

John Muir loved to roam this magical region of fabled beauty and we will have the opportunity to follow in his footsteps.


Day 1: Our official meeting time is 5 p.m. at a campground at or near Tuolumne Meadows in Yosemite National Park. At that time we can eat, get further acquainted, acclimatize, and engage in our "trailhead talk." There are no restaurants in the vicinity so please bring your own dinner to the campsite.

Day 2: After our provided breakfast, we start our adventure with a short hike of 5.5 miles and 900 feet in elevation gain to our lakeside camp, where we hope to admire alpenglow on Cathedral Peak.

Day 3: We continue over Cathedral Pass and down along Cathedral Creek to Echo Valley and our camp near the Merced High Sierra Camp. This will be a long hiking day in terms of miles; we will cover about 12 miles, but apart from 300 feet of uphill at the beginning and 200 feet up along the Merced River at the end, the rest will be a gradual descent of 2,700 feet.

Day 4: Today will be an easy day as we follow the Merced River for four or five miles to our riverside camp that's only 400 feet higher than the night before.

Day 5: We will continue to follow the Merced River as we climb up 2,300 feet in about eight miles to camp at a high alpine lake that's nestled against the southern border of Yosemite Park.

Day 6: In the morning, those who wish may hike up to Post Peak Pass and its spectacular views of Ritter, Banner, and the Minarets. After lunch, we will have a short four-mile backpack, with good views of the Clark Range, down to our idyllic camp along the Lyell Fork of the Merced River.

Day 7: We'll enjoy a layover day to explore the meadows below Mt. Lyell and Mount Ansel Adams.

Day 8: An 11-mile hike with a combined ascent of 2,000 feet, mostly along the cascades of Fletcher Creek, brings us to our campsite at Emeric Lake, where we'll enjoy the sunset panorama of Vogelsang Peak.

Day 9: We hike eight miles as we cross over Tuolumne Pass and return to our cars by noon.

The above itinerary is not rigid; how far we get each day and where we camp depends on how we feel, the weather, and other factors outside of our control. Yosemite National Park allows a maximum group size of eight for off-trail hiking; our group size is projected to be 12, hence we will be backpacking on trail (and for dayhiking off-trail, we will set out in groups of no more than eight hikers).



Getting There

The closest major airport is at Reno, which is about a four-hour drive from Tuolumne Meadows. Trip members flying to California should consider flying to Reno or the San Francisco Bay Area (about a five- to six-hour drive) and sharing a rental car with other participants. We will provide directions and a trip roster well before the trip to assist participants who want to share rides. Note that there is a $20 entrance fee per car into Yosemite National Park. (Valid for seven days. Since we will be in the Park for nine days, consider purchasing the $60 annual pass.)

Trip members should schedule their return flights for the day after the trip ends.

Accommodations and Food

We will be providing all meals and snacks; note that the first trip meal will be breakfast on Sunday, July 21, and the last meal will be breakfast on Sunday, July 28. All the meals will be pesci-vegetarian (but not vegan and not gluten-free). However, optional bacon will be provided at some breakfasts, and optional salami at some lunches.

Cooking and clean-up duties will be shared by all members of the group on a rotating basis.

Trip Difficulty

This trip is rated a 3 (on a 1 to 5 scale), but on some days the route will be strenuous. Maximum single-day elevation gains will be up to 2,000 feet and maximum elevation loss in a day will be up to 3,600 feet. We will generally hike 8 to 11 miles on travel days and the highest elevation will be 10,650 feet at Vogelsang Pass. Most days we will be hiking for 6-7 hours (including breaks), or longer if unforeseen difficulties arise. There will be some stream crossings on potentially slippery rocks or across narrow logs. Since our trip is at high elevations, very good aerobic conditioning is essential. You must have the ability to hike at high altitude with a backpack that weighs as much as 45 lbs.

Participants must maintain a regular fitness program, supplemented with weekend practice hikes while wearing the boots and pack (loaded with at least 40 pounds) you plan to bring on the trip. Also, it's recommended that you take at least one "warm-up" backpacking trip prior to this outing, at altitude if possible. If you are not in good shape, you just won’t have a good time. Be honest with yourself about your high-altitude capabilities. Altitude sickness is unpleasant and can potentially be a serious condition. Trip participants are encouraged to arrive in the area a day or two before the trip in order to begin high-elevation acclimatization.

The High Sierra is renowned for its excellent summer weather. However, extended storms can occur at any time of the year. Afternoon thunderstorms, with sudden cloudbursts of wind, rain, hail and even snow are not uncommon. Be prepared for extremes: high temperatures during the day can reach 80 degrees and, especially on this September trip, the temperature could fall into the low 20s or even teens at night.

Participation in this outing requires that you be in shape and have reasonable expectations for the trip. Recent backpacking experience and good physical conditioning are essential. A sense of humor and a patient, tolerant attitude are required for when the going gets tough. Our objectives are to enjoy the experience of spectacular alpine majesty and to complete the trip safely.

Equipment and Clothing

We provide the following group equipment items: pots, utensils, stoves, fuel, first aid kit, repair kit, trowel, ropes, and tarp. Trip members should bring their own lightweight spoon and a cup and/or bowl. Bears are present and so we will be carrying our food in bear-proof cans.

Each participant will be issued chlorine-based tablets for water treatment. You may prefer to bring along your own water purifier.

Limit your personal gear to no more than 22 pounds -- each participant's share of the commissary load could be 16-18 pounds at the start of the trip.

Make sure your backpack is large enough to carry the required loads, which on any given day could include both a large bear canister and a pot set or other bulky commissary gear.

Sturdy, fully broken in boots with rubber lug soles that provide good support are required. For shelter, tents with rainfly are strongly encouraged, and lightweight waterproof tarps are the required minimum. For rain gear, we recommend a waterproof jacket and rainpants rather than a poncho. We may encounter some dry stretches along our route, so a water-carrying capacity of at least two liters is required.

  • We suggest that you bring your own map and compass; not only is this a matter of safety, but you will have a better appreciation of where we are going and where we have been.
  • The Tom Harrison Maps "Yosemite High Country" covers the entire route. Much of our route is on the USGS 7.5 minute maps Mt. Lyell and Vogelsang Peak, and crosses short sections of the Tenaya Lake and Merced Peak maps.

"Wilderness is an anchor to windward. Knowing it is there, we can also know that we are still a rich nation, tending our resources as we should--not a people in despair searching every last nook and cranny of our land for a board of lumber, a barrel of oil, a blade of grass, or a tank of water." - Senator Clinton P. Anderson of New Mexico in American Forests, July 1963

The Wilderness Act of 1964 established the National Wilderness Preservation System, originally protecting nine million acres of national forest lands. In this Act, "wilderness" is defined as "an area where the earth and its community are untrammeled by man, where man himself is a visitor." Today more than 106 million acres are encompassed by the system. We should each consider the level of protection that the Wilderness Act has given to this area and give thought to how we will pass these areas on to future generations. 

The leaders will initiate discussions--usually while relaxing after dinner--about Public Lands and Wilderness Protection. Discussion topics will include specific wilderness legislation before Congress, recently added wilderness in California and the need to protect our nation’s magnificent wild public lands.

We will also discuss the history of the Sierra Club and its founding members and the role of Outings in furthering the cause of conservation. The Sierra Club's history is steeped in efforts to preserve endangered habitat and wilderness. The Club was instrumental in expanding protection for Yosemite a century ago, establishing Kings Canyon National Park and passing the Wilderness Act. As Club members, we have reason to be proud of these accomplishments when we hike through the region.

Sierra Club National Outings is an equal-opportunity provider and will operate under a permit from Yosemite National Park.



Peter “Fats” Elderon first backpacked in the granite state of New Hampshire, however he loves the granite of California even more. He was an assistant leader on National trips in the early 80s, but forsook backpacking while raising two daughters (with his wife whom he met in Sequoia National Park). In the last six years, he has returned every summer to backpack in the Sierra Nevada for several weeks, often with Dave Roberts, and loves to share his enthusiasm for Muir’s mountains with fellow hikers. Last year he led his first National trip (also in Yosemite).

Assistant Leader:

David Roberts participated in his first Sierra Club outing in 1969. Since 1977, he has led or co-led private backpacking trips in the Sierra Nevada and Utah. He began leading for Sierra Club Outings in 2001 with special attention to the Sierra Nevada and the canyons of Escalante. An avid photographer, he welcomes you to check out his website: He plays with the Santa Cruz Guitar Ensemble and also plays Hawaiian slack key guitar. His paying gig is working for Santa Cruz County Environmental Health Services. David stays in shape by taking a daily hike with his trusty dingo on the trails adjacent to his home in the Santa Cruz mountains.
