Gorgeous Paintbrush Canyon is a popular backpacking destination, but strong hikers can get a taste of the magic on this trip up to Holly Lake. You’ll climb to views over Leigh Lake and wander through a colorful canyon blanketed with paintbrush, gentian, and columbine blossoms, not to mention dip a toe in glacial Holly Lake, a high-country tarn at the base of 11,590-foot Mount Woodring. The trail starts on the String Lake Loop, then ascends through the rocky, rough terrain of Paintbrush Canyon to your turnaround point at the lake.
