Just so you know...
Vehicle damage or injury can occur at any time on any trail, no matter what the rating. It is each driver's responsibility to maintain their vehicle in good working condition, to be safe, and to drive within their abilities. Ask for help when you need it!
Remember, any rating system is subjective and ultimately, YOU must be the one to evaluate all roads or trails before you lock the hubs. Experience has shown me that one person's "EASY" could be another person's "DIFFICULT".
How we rate the trails:
Trail ratings are based on the last time we ran the trail. A hard rain can change a trail from easy to impassable overnight. Trails change all of the time by weather and use. A trail's rating can go up or down depending on the amount of recent rains, or amount of vehicle travel.
1.5 - GRADED DIRT ROADS: Still passable by most 2wd vehicles, however caution is required and lower speeds may be necessary for vehicles with less clearance. Small rocks (less than 5 inches) may be embedded in road surface. Sufficient room for passing on most of the road. Some steep grades possible. AWD required if road is wet or icy.
2.5 - Rugged Track: Not suitable for 2wd vehicles, or low clearance cross over vehicles. AWD required, Low Range preferred. Rutted, crossed axle terrain possible, with loose, steep climbs required. Deep sand possible. Some rock crawling possible on loose rocks up to 8 inches in diameter. Some larger rocks may be present, possibly requiring a spotter to negotiate. Small ledges possible, with larger embedded rocks present. Loose surfaces will be present, with tight clearance, smaller margin for error, and the possibility of body damage. Within the capability of any high clearance stock SUV or truck. AWD cross-over vehicles will struggle and may suffer damage due to lack of low range gearing.
3.5 - RUGGED 4X4 TRAIL
4.5 Extreme Trail: Heavily modified vehicle required. Extreme rock crawling, with very large ledges present requiring winching for shorter wheelbase (SWB) vehicles. Body and drivetrain damage likely. Very cambered terrain may cause roll-over. Vehicles will require heavy modifications. 35 inch + tires required, along with front and rear locking differentials in upgraded axles. 35-40 inch tires recommended. Winch required on SWB vehicles. Roll cages or full metal roof required. Driver must be experienced.
