Trail Difficult Ratings
When wheeling a major consideration is what level you want to wheel at.
The Minnesota Department of Natural Resources also assigns skill ratings based on colored symbols. Please see below.
Green circle (easiest)
Suitable for stock vehicles
Most highly-developed class of trails (almost road like) with no steep hills and few obstacles.
Intended for novice riders who have mastered the basic skills necessary for safe operation on well-developed trails.
Also for those lacking the experience or desire to ride more difficult trails.
Approximately 10% of trails in the system should be classified as "easiest."
Blue square (medium difficult)
May require 33 inch tires, lift, and winch/recovery gear
Suitable for the majority of intermediate riders
More difficult trails are narrower with steeper hills and switchbacks and some moderate obstacles.
Intended for OHV enthusiasts with well-developed skills seeking a reasonably challenging trail ride.
Riders subjected to higher degree of risk and exposure.
Black diamond (moderately difficult)
May require 35 inch tires, lift, lockers, and winch
Very steep grades, narrow trails, sharp alignments, rough or loose tread surfaces, and substantial obstacles.
Suitable only for proficient or expert riders to test their machines—and their own skills and abilities.
