Loved this trail, it was quite challenging, but very rewarding! Spectacular views of the peaks in RMNP and the meadow on the way to the summit (on the Garden Gate trailhead route) was breathtaking (as well as a nice respite from the steep climbing).

Nice trail, easy accomplishment for most. Several great viewpoints along the way, but the best is the summit. Terrific panoramic views from the top of the Mummy range and Long's Peak, as well as a bit of Loveland/Ft. Collins. Accessible most of the year due to it's lower altitude!

What a great hike. The hike required some effort to achieve the view, which was well worth it. Will do this hike again. Not much traffic on the trail either.

Detailed Trail Descriptions from Our Guidebooks

"This beautiful foothills hike is in a montane transition zone between the lower foothills and the higher mountains. It offers great views of the Glen Haven Tributary of the Big Thompson Canyon, the destruction done by the 2000 Bobcat Fire, and the snowcapped peaks of Rocky Mountain National Park." Read more

"This hike provides great views of Rocky Mountain National Park,without the crowded trails that are normally encountered inside the park. There are nice views along the way, as the trail climbs steeply upward.However, the best views are saved for last, as the summit provides panoramic views of Rocky Mountain National Park." Read more

John Gascoyne (And the Colorado Mountain Club)
"Crosier Mountain provides a variety of hikes along three well-maintained trails that have differing elevation gains and views. The three share a steep, final, 0.5-mile spur trail to the summit, a point that offers superb vistas of Rocky Mountain National Park’s high peaks. When the snow is deep, route finding can be difficult on Garden Gate Trail (931E). In August 2007, nine challenging geocaches for the keen hiker/geocacher were accessible by Crosier’s trail system. Be sure to find the benchmark at the summit. Four separate “ranked peaks” form Crosier’s bulk—take some time to discover them on your map and consider hiking all of them off trail once you’ve whetted your appetite on the marvelous trails to the main Crosier summit."

"There are several lengthy trails to the summit of Crosier Mountain, but this shorter option takes you through a ponderosa pine forest, past an old mine opening, to several vistas, and to a mountain meadow that is a good turnaround point. It may be simply a function of the fact that the trailhead parking can only accommodate about a half dozen vehicles, but the Crosier Mountain Trail (#931) is a great one for solitude—not to mention vistas, wildlife, and wildflowers. Begin by walking through a gate—be sure to close and secure it behind you. Walk on a gently ascending trail in a meadow where, among the mountain mahogany and rabbit- brush, you’ll see locoweed blooming in spring. Loco is Spanish for crazy, and when livestock eat this flowering plant, they exhibit the effects of the neurological damage its toxicity causes." Read more
