This trail crosses through the Comanche Peak Wilderness and into Rocky Mountain National Park. Access the North Fork Trail from the Dunraven Trailhead graveled parking lot, there you'll find room room for 23 vehicles and a vault toilet.
From the parking area the trail drops into a canyon and follows the North Fork of the Big Thompson for several miles. Bridges have been placed at some of the stream crossings. The trail briefly passes through the private Cheley Camp, please do not trespass. Before the trail departs from the river it passes through large open meadows with historic cabins, commonly known as Deserted Village and then ascends to the border of Rocky Mountain National Park.
Upon entering the park, the trail continues paralleling the North Fork of the Big Thompson as it gains elevation. Around five miles into the trail, the North Boundary Trail
will branch off to the south (left). Enjoy the views of the North Fork of the Big Thompson and its associated wetlands as you travel another mile and a quarter to a junction with the Stormy Peaks Trail
, which splits off to the north (right).
A final stretch of two and a quarter miles of trail will lead you to the beautiful Lost Lake. The lake's name will come as no surprise given the journey that you have undertaken to reach this point.
