The Rampart Reservoir is located just a few miles out of Woodland Park, Colorado. It's easy to get to from the town and is close to Mueller State Park and Pike's Peak. The trail has awesome scenery, during a good part of your ride you can look over your shoulder and see Pike's Peak in the distance.
While it is an easier trail by all accounts, the fact that you are between 9,000 and 10,000 feet means that even the simple inclines that you deal with at sea level become much more strenuous on your body. The last mile is a simple grade up and it really takes a lot out of you. Also note that they do let horses on the trail and there are always lots of hikers as well.
Location: Woodland Park, CO
