Devil’s Postpile to Shadow Lake Trail is a 21.3 mile loop in the Sierra Nevada located west of Mammoth Lakes. This route takes you near Devils Postpile National Monument, includes sections of the iconic John Muir Trail (JMT) to the less populated Shadow Creek Trail.  Along the way you’ll find stunning alpine scenery, rugged granite formations, beautiful forests, lush meadows, and pristine lakes.

DESCRIPTION
The loop begins at Devils Postpile Trailhead, located near the ranger station within the national monument. Head north on the John Muir Trail (JMT), which gently ascends, passing by alpine lakes and traversing lush meadows and forests of lodgepole pine and fir.

Just past Shadow Lake, you’ll reach a junction. From there, continue onto the Shadow Creek Trail, passing by glacier-fed sparkling lakes, framed by the dramatic jagged cliffs of the Minaret Mountains and the Ritter Range. The route then takes you along the Minaret Creek Trail, which gradually descends back to Devils Postpile and the start of the trek.

Flora and Fauna:
You'll hike through forests of lodgepole pines, red fir, and Jeffrey pines, while crossing meadows adorned with vibrant wildflowers like lupines and Indian paintbrush, especially colorful during the spring and summer months. Wildlife sightings may include mule deer, marmots, black bears, and a variety of bird species such as Clark's nutcrackers and Steller's jays.
