This is an AMAZING and easy stopover on the way from Colorado to California. It is within an hour of Hurricane and a little over an hour from Vegas.
It is a perfect water stop on hot days. The camping is only $8 per site. They are open to the elements but on a long drive it is a welcomed sidetrack to be on.
There are semi clean bathrooms, trash, covered picnic tables and water access. It is off the main highway so there is a tiny bit of noise but the landscape more than makes up for it with it's red beauty and lovely water fun! I haven't seen a ranger here in the 4 times i've stayed but the self pay station is self explanatory.
Update: The recreation area is closed for right now due to construction but will reopen soon.
