COTREX Trails and Trailheads Added in February 2019, the Colorado Trail System, now titled the Colorado Trail Explorer (COTREX), endeavors to map every trail in the state of Colorado. Currently there are nearly 40,000 miles of trails mapped. Trails come from a variety of sources (USFS, BLM, local parks & recreation departments, local governments) and are compiled by CPW contractor Natural Atlas. Responsibility for accuracy of the data rests with the source. CPW Trail Segments Recognizing that an all-inclusive, spatially-aware model of trails Colorado State Park is a useful management tool and a valuable public resource this geodatabase is designed to accomplish three objectives. 1. Inventorying all designated trails Colorado Parks & Wildlife maintain in Colorado State associate each trail segment with 38 applicable attributes. (length, width, surface, difficulty, etc.) 2.
