This is a maintained road where a high clearance 2WD vehicle is able to travel safely at low speeds on long dry straight-of-ways, without losing control due to wash boarding, ruts, or dips. All primitve dirt roads may be rocky with areas or soft gravel or sand that makes travel unsafe for sedans or RVs. Some road sections may require a high clearance 4WD vehicle, in four-wheel-drive, driven by a driver experienced in 4WD drive techniques to drive the road without getting stuck.
This road is usually open all year, but during winter months, it can be closed when the access is not cleared of snow. In winter, avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous in winter due to frequent patches of ice. Conditions can change quickly and be harsh, particularly during winter. Road closures can be frequent, so check conditions before traveling in winter!
If you dare take the risk and travel along this dusty and bumpy route, then make sure to be driven by someone who has experience of the road. Staying on track here takes oodles of concentration. There's sheer drops virtually along the entire route and enough hairpins to make a whirling dervish dizzy.
The road bad conditions, with extremely large pot holes could potentially pop a tire, crack a rim, or screw up your cars allignment.
The unpaved sections of the road can be impassable when wet. In any case, driving 4WD is recommended due to uneven surface. During and after a storm the road may be impassable, even with a four-wheel-drive vehicle and can easily get muddy if it rains making it challenging to get through.
Although it can be a reasonably easy drive in favourable conditions it also has the potential to be a very difficult track and at times impassable after wet weather. It is very important to check rainfall in this area before setting off and make sure you are well prepared for the trip.
Menacing desert terrain with numerous steep, rocky climbs. Large, sharp rocks require tight maneuvering, increasing the likelihood of tire damage. High clearance, skid plates and differential lockers required. No stock vehicles. A complex network of poorly defined roads makes route-finding very difficult, even following a GPS tracklog. Very hot in summer. Carry plenty of water. Never drive this trail alone.
Due its climb in elevation over thousands of feet, and pass through remote areas, it is important when driving in these conditions to be prepared. Check weather forecasts before leaving home, and remember that it becomes cooler and often more prone to storms at higher elevations. Be prepared with jackets, water, and emergency kit in your car.
