This playa is famous for the rocks that seemingly move on their own, creating "tracks" across the crusty surface. The movement is actually a phenomenon of erosional forces which cause the rocks to fall from surrounding mountains, leaving behind linear trails as they move. Some have moved about 1,500 feet. Because the ground is very rugged 4x4 vehicles with a higher undercarriage are recommended on Racetrack Valley Road; regular cars often get flat tires out here. Driving off-road is prohibited as is taking any rocks from the area. Please see the NPS website for more guidelines. To get there, take Scotty's Castle Road to Ubehebe Crater Road and then to Racetrack Valley Road.
Park in the parking area but walk as far as you can towards the Mountains on the other side for best pictures of the stones
