|1-2||1-2||Obstacles and terrain are relatively easy to navigate. In optimum weather conditions, some trails may not require continual use of four-wheel drive (4WD).|
|3-5||3-5||Moderately demanding. Challenge for novice drivers. Requires 4WD with 4-LO. Obstacles may include: mud holes, boulders, and streams.|
|6-7||6-7||Demanding. Challenge for most skill levels. Mud holes get deeper, boulders get larger, and climbs get steeper.|
|8-9||8-9||Very demanding. Likelihood of getting stuck is high. Mud holes may be deep and rock climbing is more arduous. Lifts and lockers are helpful.|
|10||10||Extremely demanding. Reserved for the toughest off-road trip in the U.S.A. — the Rubicon Trail. (Not recommended for Jeep Patriot, Compass, Liberty, Cherokee, Grand Cherokee, or Commander.)|
Note: Trail ratings are highly subjective. A trail that is easy for an experienced driver with a highly modified vehicle may be impassable for a novice driver in a stock vehicle. Weather conditions may also significantly affect the difficulty of a trail. Also, the difficulty of a trail may change over time, as trail use, weather, and maintenance modify the trail. Always check with the managing organization and/or recent users before planning a trip on a trail and scout ahead on foot if you are not sure of current conditions.
