Lake Solitude Trail, Mountain hiking trail in Grand Teton National Park, Wyoming.

Lake Solitude Trail is a hiking route through Grand Teton National Park that winds through forests, alpine meadows, and rocky slopes. The destination is a mountain lake at roughly 9,000 feet elevation, surrounded by steep peaks and glacial valleys.

The trail is a 4.8-mile (7.7 km) route in Grand Teton National Park, Wyoming, running from the Forks of Cascade Canyon along Cascade Creek through North Cascade Canyon to Lake Solitude. Above the lake it steepens to Paintbrush Divide, where it ends at the Paintbrush Canyon Trail. It is reached only via the Cascade Canyon or Paintbrush Canyon trails and forms part of a 19-mile (31 km) loop through both canyons.

The trail is part of a 19-mile (31 km) loop that links Cascade Canyon and Paintbrush Canyon, and hikers commonly walk it in either direction. A summer boat shuttle at South Jenny Lake cuts 4 miles (6.4 km) from the approach, a service that shapes how most visitors plan the route.

Hikers can shorten the route by taking a shuttle boat across Jenny Lake rather than walking around its southern shore. This saves energy and time for the steep climb to the lake at the end of the trail.

The trail is the only route to Lake Solitude, and beyond the lake it steepens to Paintbrush Divide, where it meets the Paintbrush Canyon Trail. Combined with the Cascade and Paintbrush Canyon trails, it forms a 19-mile (31 km) loop through both canyons.
