Thompson Lake Professional Guide
Detailed Trail Description from our Guidebook
"One word can describe Thompson Lake—inaccessible. In fact, some call Thompson Lake the most inaccessible lake in the High Uintas. Because of this distinction, we have included it in this book, though we don’t recommend it for everyone. If you’re up for some serious mountaineering and some truly remote fishing, you might like it.
From the Highline trailhead, descend 300 feet over a mile to the Mirror Lake Trail junction. Stay left and follow the Highline Trail 4.0 miles southeast across several gentle ravines to a posted sign at the Naturalist Basin turnoff . Stay right (east) at this junction, continuing on the Highline Trail. Go about 1.0 mile to another junction with the trail heading into the East Fork of the Duchesne River. Stay right (south then east) at another junction about 1.0 mile farther with the trail heading over the high pass to Four Lakes Basin. From here, a steep trail goes another 1.0 mile to Cyclone Pass and ends in a massive boulder fi eld on the other side. The boulders continue all the way to Thompson Lake."
