Trail Ratings

The Winter 4x4 Jamboree attempts to keep the trail rating current. However, weather and usage constantly alter the routes and ratings.
Heavy localized rains can change a trail from a moderate trail to impassable in an afternoon. It is always wise to obtain the most
up-to-date information prior to departing for a trip and be prepared. Remember, turning back is always an option!  

1    County dirt road maintained for high clearance 2WD and 4WD use in adverse conditions.

2    County dirt road with infrequent or light maintenance after rain or snow, 2WD high clearance with low gears, otherwise light-duty 4WD.

3    Road with frequent use, but seldom maintained. Dirt, sand and slick rock surfaces, with mud holes possible (note: maybe impassable when wet due to soil composition). 4WD recommended under most circumstances due to ruts or wash erosion.

4    Road surface consisting of loose rock, dirt, and sand with some slickrock surfaces. Erosion, washes, gulches and rock steps no higher than 12”. 4WD is recommended with good ground clearance and driving skills. Aggressive tires and a limited slip differential would be a plus. Water and mud are possible.

5    Road surfaces are rutted, rocky and sandy with steps not exceeding 14”, with considerable slickrock surfaces. Water not exceeding 12” with some mud possible. Good vehicle approach and departure angles are helpful. Tall tires (33” plus) and traction added device (lockers, limited slips) is recommended. Above average driving skills are desirable.

6    Roads are difficult with considerable erosion damage repaired just enough to be passable. Water in excess of 12” is possible with mud conditions. Steps not exceeding 24”. Tall tires (33” plus) with traction added devices (lockers, limited slips) are recommended. A winch would be a plus. Enhanced suspension travel and ground clearance are helpful. Excellent driving skills are recommended.

7    The trail consists of rock; sand and considerable slickrock with many steps exceeding 24”. Steep inclines and declines are prevalent. Enhanced off-road equipment is required including locking devices (front & rear), tall tires, maximum vehicle ground clearance, and tow hooks. A winch is desirable. Excellent driving skills are required. Vehicle mechanical or body damage is likely. Roll over possibilities exist.

8    Extreme trail similar to #7 except a bit more extreme. Excellent driving skills are required. Vehicle damage is likely. Equipment or mechanical damage is probable. Frequent use of your winch may be required.

9    Extreme and beyond, similar to #8. Vehicle damage is likely. Excellent driving skills are required. Rollovers are very common. Winches, spare parts and tools are recommended. Be prepared to spend the night on the trail. Beyond the capability of most modified stock vehicles.

10  Let the carnage begin! Buggy territory. Street driven 4X4’s should not attempt this trail. Modified factory vehicles will not be able to complete this trail.
