Blue Sky Trail - Mountain Biking, Trail Running

Blue Sky Trail Map and Parking

The Blue Sky trail is a 5.5 mile trail that connects Horsetooth Mountain Park to Coyote Ridge Natural Area and Devil's Backbone Open Space. The primary activities are mountain biking and trail running but horseback riding and hiking are also allowed. Rock climbing, however, is not allowed. The following trail description describes a mountain bike ride that started at the Soderberg trailhead and headed south on the Blue Sky trail. The Soderberg trailhead is located 30 minutes from Fort Collins, Colorado and is inside Horsetooth Mountain Park. Horsetooth Mountain Park requires a parking fee of $6. At the Soderberg trailhead, there is a water fountain and restrooms. Leashed dogs are allowed on Blue Sky trail but not on the connected trails in Rimrock Open Space or Coyote Ridge Natural Area. Cell phone service was strong at the trailhead but was not tested while on the trail. Finally, the Blue Sky trail can also be accessed from the trailheads at Coyote Ridge Natural Area and Devil's Backbone Open Space but they require more rigorous mountain biking before reaching the Blue Sky trail. The Blue Sky trail can be seen in the following Google Map as the blue line running down the center.

Inlet Bay Trail

From the Soderberg trailhead, the Inlet Bay trail is 1.2 miles of wide, smooth, and flat trail that provides a nice warm up for the more interesting Blue Sky trail. It passes campgrounds on its way towards the Blue Sky trail.

Blue Sky Trail

The Blue Sky trail is 5.5 miles of eclectic trail that hovers around an elevation of 5,500 feet.
The trail boasts stretches of curvy, rolling terrain and short bursts of incline as is seen in the following picture.
In the winter, the vegetation is not a factor but in the spring and summer it can grow across the trail providing for some unpleasant brush-ups with thorny plants.The subsequent picture shows a segment of trail that is open and flat and, thus, it appropriately illustrates the fact that there is almost zero shade to be found while on the trail.
The most pronounced climb is experienced at the section of trail heading up towards the intersection with Rimrock Trail (which leads to Coyote Ridge Natural Area).
The subsequent picture was taken in June from a similar location and highlights the stark differences between winter and summer. The next picture shows the same ridge but was taken from a distance.

First intersection with Indian Summer Trail

The Indian Summer trail is a horseshoe shaped trail that intersects with Blue Sky on both ends of the horseshoe and, thus, can only be accessed from Blue Sky. For pictures, video, and description, please read the Indian Summer trail blog post. Continuing past the first intersection with the Indian Summer, the Blue Sky trail levels off.
What's more, the Blue Sky trail turns into a service road (temporarily) as can been seen in the following picture (which faces north). Therefore, it is more fun to mountain bike on Indian Summer instead of along this section of service road.

Second Intersection with Indian Summer Trail

After passing the second intersection with the Indian Summer trail, the trail returns to the ridge line and heads up towards to the Laughing Horse Loop trail (ridge line seen in background).
The following picture shows where we turned around which was a tricky staircase that leads up towards the Laughing Horse Loop trail.
In sum, Blue Sky trail is pure fun (i.e., no dismounts or other headaches) and, thus, a must-do for mountain bikers and trail runners of all skills levels. Blue Sky contains a fun and challenging fusion of technical and non-technical sections comprised of a blend of curvy trail, fast rolling trail, manageable rocks, and a couple of pronounced climbs. The only downside of the trail is the dominance that the sun can impose on passersby in the middle of the day. The following is a list of more mountain bike trails along the northern Front Range:

• Boulder / Lyons - Hall Ranch and Rabbit Mountain
  
• Poudre River Canyon - Hewlett Gulch and Young Gulch
  
• Fort Collins - Maxwell to Pineridge Natural Areas, Maxwell to Reservoir Ridge Natural Areas, Mountain Bike Skills Parks in Fort Collins, and Lory State Park Valley Trails
• Fort Collins / Loveland - Indian Summer via Blue Sky, Bobcat Ridge Natural Area, Coyote Ridge Natural Area, and Rimrock Mountain Bike Trail
