This is a great driving tour. The whole route is one-way, so be sure to bring lots of water and a spare tire! You start a flat gravel road, just outside of Rhyolite (coming from Furnace Creek). After half an hour, you start climbing and drive over some really beautiful mountain passes. The road is really narrow and very steep sometimes. About halfway, you reach a little mining ghost town called leadfield. Get out of the car here and walk around; this is like a time machine!
After the ghost town, the road descends into a narrow canyon. At times, the canyon walls are as high as 100 meters. A great place. At the end of the tour, you can hike on foot through another narrow canyon.
This is really one of the most beautiful parts of the Death Valley National Park!
