Don't get me wrong it is very beautiful especially if you like to go on hikes and/or have a family you can explore with. The loop is half rock half sand with great scenery the whole way.... If you have never been it is at least worth the trip to make up your own mind. Go with someone that can show you around a bit.
And Valley of Fire opened a full hook up camping area if you like to have relaxing/quit trips... about $14.00 a night I think
