Trail
Ratings Defined:Trail ratings
are very subjective. Conditions change for many reasons, including weather and
time of year. An easy trail can quickly become difficult when washed out by a
rainstorm or blocked by a fallen rock. If any part of a trail is difficult, the
entire trail is rated difficult. You may be able to drive a significant portion
of a trail before reaching the difficult spot.
Easy: Gravel, dirt,
clay, sand, or mildly rocky road. Gentle grades. Water levels low except, during
periods of heavy runoff. Full-width single lane or wider with adequate room to
pass most of the time. Where shelf conditions exist, road is wide and well
maintained with minor sideways tilt. Four-wheel drive recommended on most trails
but some are suitable for two-wheel drive under dry conditions. Clay surface
roads, when wet, can significantly increase
difficulty.
Moderate: Rutted dirt or
rocky road suitable for most sport utility vehicles. Careful tire placement
often necessary. Four-wheel drive, low range, and high ground clearance
required. Standard factory skid plates and tow hooks recommended on many trails.
Undercarriage may scrape occasionally. Some grades steep but manageable if dry.
Soft sand possible. Sideways tilt will require caution. Narrow shelf roads
possible. Backing may be necessary to pass. Water depths passable for stock
high-clearance vehicles except during periods of heavy runoff. Mud holes may be
present especially in the spring. Rock stacking may be necessary in some cases.
Brush may touch vehicle.
Difficult: Some trails
suitable for more aggressive stock vehicles but most trails require vehicle
modification. Lifts, differential lockers, aggressive articulation, and/or
winches recommended in many cases. Skid plates and tow hooks required. Body
damage possible. Grades can be steep with severe ground undulation. Sideways
tilt can be extreme. Deep water crossing possible. Shelf roads extreme narrow;
use caution in full-size vehicle. Read trail description carefully. Passing may
be difficult with backing required for long distances. Brush may scratch side of
vehicle.
