Valley of Fire State Park in Nevada is located 16 miles south of Overton, Nevada and is about an hour drive from Las Vegas. There is a fee to enter the park it costs about $10ish from what I remember and is well worth it. Great scenic views, cool rock colours and formations. Plus there is some wildlife and a few places to camp.
Valley of Fire State Park
This was a cool place. I think its about 45min from Los Vegas. You can see mountain sheep, really cool coloured rock formations and a nice drive. For the price its certainly worth it. I believe you can camp in the park as well. Not sure about hookups... but would be a nice place to stay.
