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. Determine and track if the following 11 uses are permitted on each trail segment: 1:Hiking, 2:Biking, 3: Equestrian 4:Pets, 5:Snowshoeing. 6: Cross Country Skiing, 7: Snowmobiling, 8: Grooming, 9: OHV 10: Other Power Driven Mobility Devices (OPDMD), 11:Wheelchair friendliness (Not ADA accessibility)

3. Model Colorado State Park Trail system in a spatially aware three dimensional space and associate each trail segment to 38 attributes that can be used to producing a set of standardized trail maps for public and internal use.

Colorado Parks and Wildlife

Map displaying locations of vendors in Colorado where you can purchase a CORSAR card.

Colorado residents and visitors are well served by dedicated volunteer search and rescue teams, but mission costs are often in the thousands of dollars. By purchasing a CORSAR card you are contributing to the Search and Rescue Fund, which will reimburse these teams for costs incurred in your search and rescue. Funds remaining at the end of the year are used to help pay for training and equipment for these teams. Anyone with a current hunting/fishing license, or boat, snowmobile, ATV registration is already covered by the fund.

The card is not insurance and does not reimburse individuals nor does it pay for medical transport. Medical transport includes helicopter flights or ground ambulance. If aircraft are used as a search vehicle, those costs are reimbursed by the fund. If the aircraft becomes a medical transport due to a medical emergency, the medical portion of the transport is not covered.

The CORSAR cards are available for $3 for one year and $12 for five years, and can be purchased at over 300 retailers in the state.
