Mammoth to Yosemite Valley Hike

The John Muir Trail is one of the finest hikes to be found anywhere in the world. The hike from Yosemite National Park to the high point of the lower forty-eight states, Mount Whitney, is about 200 miles and is a twenty day trip. But not everyone can take the time to do this. This trip extends our popular Mammoth to Tuolumne hike by two days and take you all the way into the fabled Yosemite Valley

Return to Sierra Backpacking & Hiking

This trip can be made in either direction but we like to start from Mammoth Lakes since it avoids the problems of obtaining a wilderness permit in Yosemite, which can be very difficult. This also enables you to spend the night before in Mammoth and gain some acclimatization to the elevation in a comfortable setting. While this trip can be done in less than four days, our goal is to enjoy the hike and not beat ourselves up. That way we can split the days into easy segments that allow you to forget the city, work and all those things that come with modern life. You’ll have time to sit by a lake in the sun and read a book, go fishing or take an afternoon hike without the overnight pack.

Day 1

We head up the rushing San Joaquin River from Agnew Meadows along the River Trail. Passing 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 make this not too long a day.

Ending elevation 10030 feet
Distance 4.5 miles with 1050 feet of gain and 350 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 and set up camp.

Ending elevation 9650 feet
Distance 7.5 miles with 2000 feet of gain and 1500 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 to into Lyell Canyon. Above us rises Mt Lyell, the high point of Yosemite National Park, and we start a steady drop to into the wide glacially carved valley of Lyell Canyon. We plan to camp near the Tuolumne River in the base of Lyell Canyon.

Day 4

All downhill now to the roadhead at Tuolumne Meadows through Lyell canyon, past the Lyell Fork of the Tuolumne River lazily meandering its way. We take time to pick up a food resupply in Tuolumne Meadows (and maybe an icecream at the store before heading along the JMT and climbing to camp near lovely Cathedral Lakes .

Ending elevation 7190 feet
Distance 7.5 miles with 1180 feet of gain and 3280 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 in Late morning to early afternoon. We shuttle back to Mammoth where you can stay and delay the return to the big city or if time is short then head home refreshed and rejuvenated by the High Sierra
