Adults only. no thanks.
One of the most beautifully alien and under-rated parks in Utah. Bring plenty of supplies especially water- this park is desolate. Even the entrance is about 20 miles into private property. There were many families in the park once we pulled into the service area but I would not want a flat tire here even in peak season.
GO NOW. The park is currently under evaluation by the Park Service due to some high profile incidents of people trashing the place. I would not be surprised if they closed large areas off for preservation. Right now you can walk right up to the hoodoos and through the entire place.
