Hard 10: When you no longer care about the sheet metal on your truck and rolling it over might be considered fun, then this is your trail.


This rating system is to be used as a base for the average driver. I have seen a very good driver in a 2WD truck with a rear locker complete the Red Lake trail which is a rating 8. Modified 4WD vehicles have gotten stuck and rolled over on moderate trails because the driver was careless or didn't know what they were doing.

This rating system was upgraded from (Easy, Moderate, Difficult, Hard) to a (Easy[1-3], Moderate[4-6], Difficult[7-9], Hard[10]) system. This was done to further separate the difficulty of the trails so that you will know more about what you are getting into.
This system was developed from a combination of Backcountry Adventures rating system and Toyota Territory Off-Roader's Association rating system. I did not copy either rating system, but credit is still due.
