North of Jackson at Jenny Lake in Grand Teton National Park, the Cascade Canyon Trail and Lake Solitude Trail can be combined for a 7 mile route up to the beautiful Lake Solitude. The route starts with an early morning boat shuttle across Jenny Lake (6,800 feet). You will want to start very early to avoid the heavy tourist crowds.
The goal maybe Lake Solitude at 9,000 feet, but the views of Hidden Falls, Inspiration Point and Grand Teton (13,772’) lead you to believe that it couldn’t get any better – but it does. Lake Solitude is situated in a glacial cirque of steep cliffs.
Once up at Lake Solitude (9,080 feet), you can either return by the same route, which will most likely be very crowded, or you can head east up the Paintbrush Canyon Trail to Paintbrush Divide (10,740 feet). The Paintbrush Canyon Trail continues east to the String Lake Trail (aka Valley Trail) that leads back to the boat shuttle dock.
The main trailhead parking area is the massive parking lot on the south end of Jenny Lake. You will need to walk down to the shoreline to pickup the shuttle boat heading across the lake. There is a small fee for the boat, but it is worth it to get a jump on the foot traffic. There is a shuttle boat every 15 minutes.
Overall, Cascade Canyon / Lake Solitude Trail is the 2nd most popular hiking trail of all 18 hikes in Wyoming.
