I compiled some GPX/KML files for Colorado 4WD roads and Trails that I have acquired and reorganized. This data is primarily a compilation from two data sources available online. The first is www.Traildamage.com
which is primarily for 4 wheel drive vehicles. The second is from IntrepidXJ’s Adventure Weblog: http://www.myxj.net/blog/trails
. Other sources used to create Google Earth Tracks are visual inspection of Google Earth, a book titled “Colorado Trails – Central Region”, and various National Forrest Service online data. The most complete data is compiled into a Google Earth KMZ file that includes 355 fire roads and trails in 36 of Colorado’s Counties. The data obtained from the website Trail Damage is also available in GPX format. To convert the other KML files not already in GPX format, just download and use GPS Babel to convert from KML to GPX format.
The Google Earth KMZ file includes 3 subfolders “Colorado Motorcycle & 4WD Roads”, “Scenic Paved Roads”, and Colorado Counties”. The Trails in the “Colorado Motorcycle & 4WD Roads” are segregated into the 36 Colorado counties. There are occasional overlaps with some of the roads and trails, but not too many. Unfortunately the “Scenic Paved Roads” is currently a little light, as it only contains the following 3 roads: “Peak to Peak Scenic Drive”, “Independence Pass Road”, and “Highway 285”. It may not be possible to convert the last three to GPX files as they were obtained from ESRI SHP files and probably contain too many points. The KML of the Colorado Counties was useful in compiling and segregating this information and may be useful to you.
The Excel Spreadsheet titled “Colorado Motorcycle Trails.xls” contains all of the roads and trails in the Google Earth KML file categorized alphabetically by Colorado County and alphabetically by Trail. It includes the rating system from the web site Trail Damage and up to eight nearby trails for each trail. This file could be easily modified by those Colorado ADVRIDER’S who are both experienced and interested in providing an actual difficulty rating as well recommended motorcycle size.
Lastly I have not ridden over most of the roads contained in this compiled data and as such cannot personally attest to the accuracy of the information. However, I would not have included the information if I did not have a degree of trust from the various information sources.
You may notice that I originally created this post for ADVRIDER’s regional Rockies thread, so that maybe some of the people in the area would rate the trail/road difficultly.
