A very short but kind of rough road right off of Valley of Fire Hwy less than two miles from the Parks north entrance. Free boondocking with no amenities. Follow the road and find your spot! You can see the traffic going to and from the park, but it is not a nuisance. The park is technically closed from sunset to sunrise so the only traffic is the occasional camper, arriving at the campground within the park. There are so many trails and points of interest to visit inside and outside the park. I highly recommend paying the price to drive through the park and then through the Lake Mead national recreation area into Henderson, Nevada near Las Vegas. The road along Lake Mead is as beautiful as Valley of Fire is!
