Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Castle Rock) to Point B.
If you need the driving distance (or directions), we recommend that you use one of the Mapping Services listed on our Map Page for Castle Rock. Since we usually use Google Maps, we've provided the following link for your convenience: Google Map and Driving Directions starting from Castle Rock
