Crosier Mountain is 9,250 feet tall and especially in comparison to the peaks in the nearby Rocky Mountain National Park, incredibly dry, open, and arid. Crosier Mountain is accessible from three different trails Garden Gate, Rainbow Trail/Gravel Pit, and Glen Haven, the trailheads of which are all located within about 8 miles of each other. Dogs are allowed on all of these trails, which are also popular with mountain bikers and horseback riders. Regardless of which trail you take, Crosier Mountain is a challenging hike, but it offers amazing panoramic views of the Twin Sisters Peaks and Longs Peak to the south in RMNP, Signal Mountain to the northwest, and the foothills and plains of Front Range to the east.
