Some of the park's most fascinating landscapes can be observed from this 18-mile dirt road. Parts of the journey are rough, so make sure you have a 4X4. Sights to see include a 100-year-old stone dam called Squaw Tank, defunct mines, and a large plain with an abundance of Joshua trees. There are 16 stops along the way, so give yourself about two hours to make the round-trip.
