Paintbrush Canyon Trail, Mountain hiking trail in Grand Teton National Park, Wyoming.

Paintbrush Canyon Trail is a 9.1-mile (14.6 km) hiking trail in Grand Teton National Park, Wyoming. It begins at the String Lake trailhead, follows the lake's west shore, then enters Paintbrush Canyon and climbs to Paintbrush Divide. A junction leads to Holly Lake, and the final 3.9 miles (6.3 km) gain altitude steadily.

The trail lies in Grand Teton National Park, established in 1929, and its route from String Lake through Paintbrush Canyon to Paintbrush Divide appears on park trail maps. The east approach to the divide stays steep enough that an ice axe may be needed into July. A 19-mile loop links it with the Lake Solitude and Cascade Canyon trails, gaining 4,900 feet.

The trail begins at the String Lake trailhead and follows the lake's west shore, a stretch also called the String Lake Trail. Two camping zones lie within Paintbrush Canyon and a designated campsite sits at Holly Lake, all reachable with a permit. A popular 19-mile loop combines this trail with the Lake Solitude and Cascade Canyon trails, gaining 4,900 feet.

Access is from the String Lake trailhead, where the route follows the lake's west shore before entering the canyon. The trail splits toward Holly Lake or continues to Paintbrush Divide, and the east approach to the divide is steep and may need an ice axe through July. Camping is allowed only in two canyon zones and at the Holly Lake site, all by permit.

At the highest point, Paintbrush Divide, hikers gain unobstructed views of Mount Moran and neighboring peaks that look distinctly different depending on the season and time of day. Few other routes in the park offer such a direct vantage point.
