We've really enjoyed our three night stay at Old Dutchman State Park. Grounds are well kept. Staff very friendly. Showers available. Campsites are well spaced especially if you are lucky to reserve an outer one. Great hiking trails from campsite to the Superstition Mountain.
Only hesitation are the limited toilet locations. There are only two for a rather large campground + cabins. Closest bathroom for the 105-134 loop was a 15 min walk. As someone who tents rather than RV the distance was an issue given the lack of privacy between sites.
