If Sin City isn't really your scene, consider driving about 50 miles north of Las Vegas to explore one of the area's best kept secrets. Though considered Nevada's largest State Park, the Valley of Fire makes up just a small fraction of the state's 47.5 million acres of BLM land. Here, you can marvel at 3,000 year-old Indian petroglyphs and petrified wood, and walk among sherbet-hued rock and fiery waves of sandstone all in the same day.
But what makes this place even better is that you can camp nearby for free. If you know where to look.
Located about six miles west of the Park's western entrance is a spacious (yet secluded) section of BLM land where you can camp for the night. Technically the Park mentions this spot as "overflow camping", but regardless of whether its camp sites are full, this is still a great option.
How to Get There:
The turn-off for this camp area is right after Mile 6 coming into Valley of Fire from I-15. There is a short gravel road to get into the camp area. There are several spots available, each with a fire ring. Personally, we had no trouble fitting out 28-foot EarthRoamer.
One point to note is that there is no shade and no water. Since you're in the desert, this should go without saying, but make sure you bring enough water to drink and stay in the shade of your tent or tarp to get out of direct sun. There are also no tables or bathrooms so bring your own toilet paper or stop into the truck stop in Crystal to freshen up.
