Trip Highlights

  • Explore deep into Yosemite's Hetch Hetchy Valley on foot
  • Hone or expand upon backpacking skills while learning from expert guides
  • Hike past fields of wildflowers, tumbling waterfalls, open vistas, and more
  • Stay at a backcountry campsite and enjoy a day of hiking with daypacks

Hetch Hetchy Valley, etched by glacial erosion millions of years ago, has often been spoken of as Yosemite Valley's sibling. Although the valley underwent a massive transformation when a dam was built in 1913, stunning trails and vistas remain for backpackers, wildflower enthusiasts, and waterfall lovers. Get up close and personal with Yosemite National Park, traveling on foot through a landscape that few people experience away from the crowds.

Join REI on a foray into the Sierras and enjoy this backcountry experience as our guides share their love of one of the world's most revered wilderness areas. A stunning trip for the experienced and beginner backpacker alike, we carry all our belongings on our back and discuss basic skills like map and compass use, backcountry cooking, and minimal impact camping. Get away from your daily routine as we explore the rich environmental and political history of Yosemite.

Looking for more ways to get away from the crowds and explore Yosemite’s backcountry? Explore Tuolumne Meadows and beyond on our High Country backpacking adventure or set yourself up for some stunning views on our Yosemite Valley backpacking adventure.

Trip Itinerary and Details

Important Notice: Day 1 is the day you should plan to arrive at the meeting point for the trip. This may require departing your hometown one or more days in advance and traveling on an overnight flight.

  • Day 1 - Meet at the Backpackers' Campground to enjoy dinner and orientation.

    This trip begins in Yosemite National Park, CA. Today you will meet your guides and the other group members at 4:30pm at the Hetch Hetchy Backpackers' Campground, located just south of the dam next to the parking area. We will enjoy a full trip orientation, learning about John Muir's efforts to fight the Raker Act, the act that granted permission to build O'Shaughnessy Dam and flood the Hetch Hetchy Valley. "As well dam for water-tanks the people's cathedrals and churches," Muir said, "for no holier temple has ever been consecrated by the heart of man." We will do a full gear check and enjoy dinner together at camp.

  • Day 2 - Set out for camp, taking in views of Tueeulala and Wapama Falls.

    We enjoy breakfast in camp before packing up. We will start out hiking on-trail to our backcountry campsite near Rancheria Falls. This is typically a full first day of backpacking, with time along the way for lunch and teachable moments. Today's trail runs above peaceful Hetch Hetchy Valley and reservoir traveling at around 4,000 feet. We will stop for lunch and the photo opportunities presented by Tueeulala and Wapama waterfalls, as well as the plethora of wildflowers in their full spring bloom at our feet. Your guides share the human history of this valley, and the healthy debate around its use and protection. This will be a 6-mile hike, beginning at around 3,800' and ending at camp near rushing Rancheria Falls (4,700') swollen with spring snow melt. A refreshing dip in the creek washes away the miles. All meals provided.

    Backpacking: 6.4 miles; ~600' elevation gain

  • Day 3 - Donning daypacks, hike the lush Tiltill Valley.

    After breakfast, we continue exploring the Yosemite backcountry. Today, we'll load our daypacks and set out for Tiltill Valley. We'll look for wildlife and more flowers along the way and experience the changing climate zones as we climb up another 1,000 feet. Lunch will be in the lush Tiltill Valley meadow surrounded by pines among the deer and flowers. Hetch Hetchy has been called Yosemite Valley's little sister, equal in beauty to Yosemite Valley's waterfalls and domes, although much more intimate. Look forward to a refreshing evening dip and dinner as we enjoy our last night beneath the bright Sierra stars. All meals provided.

    Day-hiking: 5.6 miles; ~1050' elevation gain and loss

  • Day 4 - Break camp and return to the trailhead.

    We'll enjoy breakfast before breaking camp and making our way out of the backcountry. Retracing our path through forest and flowers and misty rainbows at the base of the waterfalls, we complete our journey and come to understand why the fight to reclaim this valley continues to this day. We plan to arrive back at our trailhead by 4:00 p.m. but there is no guarantee that we'll make it to our vehicles by then, so those flying out of Fresno should plan no flights before 9:30 p.m. and those flying out of Oakland should plan no flights before 10:30 p.m. Breakfast and lunch included.

    Backpacking: 6.4 miles; ~600' elevation loss
