Trail Overview


Difficult: Conditions vary depending on time of year and wind conditions. Routes shown here are easy to moderate except if you attempt to drive up larger dunes, like Oldsmobile Hill. Use extreme caution on steep slopes. Downwind side of dunes can be extremely soft, where it's easy to get stuck or even roll over. Route-finding can be challenging during the off-season when no tire tracks are present.


Only the dunes south of Highway 78 are open to vehicular recreation. A lawsuit led by the Sierra Club in 2000 closed more than half of what used to be open south of Hwy. 78. The lawsuit continues today, but OHV enthusiasts remain hopeful that this 'temporary closure' will eventually come to an end. During major winter holiday weekends, the dunes often see more than 150,000 visitors.
