“A nicely forested trail meandering past high alpine lakes to the Continental Divide.”— Tom Robson
From the Diamond Lake Trail junction, it is another 0.6 miles to Jasper Lake, a very popular camping area with limited designated sites. The trail continues for a mile to Devil's Thumb Lake. Several switchbacks lead up the steep side of a ridge to reach the Continental Divide. Snow and ice can be a problem until late July.
From the top, it is 0.6 miles to the north to Devil's Thumb Pass and three miles to the King Lake Trail #901. It is not difficult to see the High Lonesome Trail below and west of the Devil's Thumb Trail. Finding the Devil's Thumb Trail from the High Lonesome Trail is challenging.
