Paintbrush Canyon, Mountain canyon in Grand Teton National Park, Wyoming, United States.

Paintbrush Canyon is a gorge in Grand Teton National Park that cuts through granite formations and alpine meadows, culminating at Paintbrush Divide at about 10,700 feet. The route passes through multiple ecological zones and opens onto views of surrounding peaks and mountain lakes.

Paintbrush Canyon was cut by glaciers that retreated at the end of the Last Glacial Maximum, roughly 15,000 years ago, leaving a U-shaped trough running southwest to northeast between Rockchuck Peak and Mount Saint John to the south and Mount Woodring to the north. Its lower end meets Leigh Lake, with Holly Lake set in the upper canyon.

Paintbrush Canyon Trail begins at String Lake and climbs to Paintbrush Divide, a 10,720-foot pass. It is a segment of the Teton Crest Trail, which runs 39 miles from Teton Pass along Wyoming Highway 22 to String Lake across the southern Teton Range. Hikers on the 19.2-mile circuit also pass Lake Solitude.

The trail through the canyon is demanding and requires good stamina plus proper mountain gear. Visitors should prepare for changing weather conditions and rough terrain sections.

Paintbrush Divide retains snow coverage until mid-July and demands winter gear for early season attempts. This condition transforms the crossing into a completely different experience depending on timing.
