This is a part of the Chicopee woods trail system. The Coyote Loop is a standalone loop that begins back down the road a little ways from the trailhead. While not overly technical, the keepers of the trail system rate this a black diamond. This rating is probably due to some of the sharp elevation changes, roots, a nice rock garden (which can be bypassed) and a serious section of switchbacks. While this loop is short, the elevation changes can make it a real challenge, especially when you're trying to go fast.
