Raven Run is comprised of one main four mile loop (red trail), plus many other trails crisscrossing throughout the nature sanctuary, including the meadow trail and the "flower bowl" trail. There are also short white trails that go to small sites such as the ruins of an old grist mill on the creek. The overlook, which gives you views of the Kentucky River from high atop a bluff, is probably the main attraction. The main loop is moderately difficult and other trails vary. The nature center, where you sign in and collect recycled maps is a small room containing a little wildlife (two turtles and a snake) as well as a wealth of information about the plants and animals you may encounter in Kentucky. We live in Lexington, just about 20 minutes from Raven Run and go often. The trails are well maintained and don't get too overgrown, but there isn't anything to distract from the "nature" part of the sanctuary, either. We often take out-of-town family and friends there and you couldn't ask for better hiking trails so close to a city like Lexington.
