Parker Lake Trailhead to Ediza Lake

This ambitious out-and-back route begins at the Parker Lake Trailhead and climbs deep into the rugged terrain of the Ansel Adams Wilderness. Covering 39 miles round trip with over 10,000 feet of elevation gain, this route weaves through dense forest, high alpine passes, glacially carved basins, and some of the most scenic lake country in the Sierra. With sustained climbs, remote stretches, and variable trail conditions, this route is best suited for experienced backpackers seeking solitude, challenge, and stunning high-country views.
Route Description
Start from Parker Lake Trailhead and head up the Parker Lake Trail, quickly gaining elevation and views. Connect to the Parker Bench Trail, then descend to Silver Lake Campground. From there, follow the Rush Creek Trail and turn onto the Spooky Meadow Trail. This leads to the Clark Lakes Trail, eventually connecting to the Garnet Cutoff Trail.

Follow the Garnet Cutoff to the John Muir Trail, then take the Shadow Creek Trail south to the Ediza Spur Trail. Follow the spur around Ediza Lake, a spectacular final destination surrounded by dramatic peaks.

After hiking around Ediza Lake you can retrace your steps along the same trail network to return.

Note. This route intersects with several other trails, offering plenty of opportunities to shorten, extend, or explore alternate paths along the way.
Flora and Fauna
This route takes you through a diverse range of Sierra ecosystems, beginning in montane forests dominated by Jeffrey pine, lodgepole pine, and red fir. As you climb higher, the landscape opens up to subalpine meadows, granite benches, and alpine basins dotted with wildflowers during peak bloom in mid to late summer. Lupine, paintbrush, and columbine are commonly seen along the trail. Wildlife is abundant—mule deer are frequently spotted in the early morning and evening, while marmots and pika are active in the rocky highlands. Black bears are also present throughout the region, so proper food storage is essential. Birders may catch glimpses of Clark’s nutcrackers, mountain bluebirds, and the occasional golden eagle soaring overhead.

Water must be treated before consumption and can be collected from various streams and lakes. OVERNIGHT CAMPING PERMITS
Permits are required for overnight camping and backpacking trips and can be obtained at www.recreation.gov.
