Blue Sky is a very casual ride with great flow over lightly rolling terrain. It's essentially all singletrack with only one section of steps that most people will walk, though advanced riders can usually figure out a line. The Indian Summer loop adds a couple miles and a few hundred feet of climbing, and together they make for a perfect after-work ride that keeps you coming back again and again.

Note that Blue Sky does have quite a number of blind turns and the trail can be quite popular on weekends, so be careful.
Need To Know
Parking is run by Larimer County Parks, and is $7/day or yearly passes are available (starting at $75/year). There is an outhouse and water fountain. The parking lot closes at dusk.
From the parking lot, you'll find the trailhead near the outhouse which you'll take to the right. Continue straight on the obvious trail and you'll go through an underpass around half a mile in.

At about 3.5 miles you'll hit the intersection with the Rim Rock trail. Continue straight (right) on Blue Sky to descend towards Indian Summer. Watch your speed, as the bottom of this descent turns somewhat sharply to the right on usually very loose sand.

When the singletrack becomes road, follow this to the left for about half a mile before the trail continues on the right. Shortly after you'll hit the Indian Summer intersection which you follow up to the right. This will climb up a few hundred feet on low-grade switchbacks before you get to descend back down on intermediate terrain.

At the bottom, you'll pop out where you initially turned left onto the road. Blue Sky continues straight ahead. Take this back to the trailhead.
