“A loop from the open meadows of Moraine Park up to Cub Lake and back along the Big Thompson River.”— Kristen Arendt
The trail's grade will remain very manageable as it contours to the west, just north of Sheep Mountain. Once the trail turns southward (left), the grade steepens drastically. This is the short but steep approach to Cub Lake.
Cub Lake makes for a great rest stop or picnic destination. Enjoy the richness of your surroundings before continuing on Cub Lake Trail. The trail descends from the lake for just under a mile to a junction with Fern Lake Trail at the Pool.
From the Pool at the junction take a right onto Fern Lake Trail and descend alongside the Big Thompson River. The canyon through which this trail runs is stunning - the northern wall rises abruptly over 1,000 feet above the valley floor.
Once you reach the Fern Lake Trailhead, continue on the Fern Lake Road for approximately one mile. This road will loop you back around to the Cub Lake Trailhead to finish the run.
