Visit Death Valley National Park. You can first visit the Furnace Creek Vistor s Center for maps and some good exhibits. Scotty s Castle, Eureka Dunes, Telescope Peak, and Dante s View are some good places to visit. There are many hiking trails to explore. I liked the Natural Bridge Canyon Hiking Trail and Golden Canyon Trail. Both are short hikes. You can also camp, bike, and birdwatch in the park.

The only thing I remember about that area is that Ft. Irwin is forty mile s into the desert from Barstow which is a truck stop between L.A. and Vegas. Nothing at all to do.
In Death Valley I just took in the terrible silence. Its awesome.
