Glamis, Oldsmobile, Sand
One route will lead you to Glamis and Oldsmobile Hill in the north central area. The other drives along the edge of the dunes on the western edge. The area is open to both licensed and green-sticker vehicles. Flags are required at the park, and fees and permits are necessary here. Camping is available, and this area can get very crowded so get there early to get a spot. There is a Store at Glamis that offers supplies and fuel.
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.
