Overview
The North Lake to Grass Lake trail is a short but rewarding hike in Bishop Creek Canyon. Following the Piute Pass Trail, this route winds through aspen groves, meadows, and creek crossings before arriving at Grass Lake — a quiet alpine tarn tucked beneath rugged peaks. In fall, the aspen canopy turns gold, making this one of the most accessible and photogenic leaf-peeping hikes in the Eastern Sierra.

Trail Description
Starting from the North Lake Campground, the Piute Pass Trail climbs steadily but gently through stands of aspen. The trail passes several small meadows and follows alongside Bishop Creek, where early-season runoff fills the air with the sound of rushing water. In about a mile, you’ll reach Grass Lake, a small alpine lake set in a sheltered basin with dramatic granite walls above. The shoreline is dotted with willows and aspens, offering plenty of spots to relax, take photos, or enjoy a picnic. You can return the way you came or follow the trail that runs along side Lamarck Creek to extend your hike and create a loop.
Best Season to Hike
• Fall (late September–early October): Peak aspen color
• Summer (July–September): Snow-free and wildflowers in the meadows
•Spring (June): Possible snow patches but great water flow in creeks
Flora & Fauna
• Aspen groves that blaze gold in fall
•Summer wildflowers like lupine and paintbrush
•Mule deer, marmots, and chipmunks are common
Geology
Grass Lake sits in a glacially carved basin beneath granite cliffs typical of the Sierra Nevada. Moraines, polished granite, and talus slopes frame the lake, telling the story of Ice Age glaciers that shaped Bishop Creek Canyon.
History
The Piute Pass Trail has been a travel corridor for centuries, originally used by Indigenous peoples as a trade route across the Sierra Crest. Today, it serves as an entry point into the John Muir Wilderness and a popular access point for day hikers and backpackers.
Know Before You Go
Afternoon thunderstorms are common in summer. Start early and be off the pass by midday. If you hear thunder and see lightning on an exposed trail, your immediate priority is to seek shelter and minimize your exposure to the storm. Trail can be icy or muddy early in the season. Mosquitoes are very active in June and July.
Driving Directions
From Bishop, take Highway 168 (West Line Street) toward Bishop Creek Canyon. After about 18 miles, turn right on North Lake Road and follow it 2.5 miles to the parking lot.
Parking
Limited parking is available at the North Lake Hiker Lot. Arrive early on weekends or during fall color season.
