Forest in Arizona!
Well marked on the highway.
We did not venture far up the road as the second site we saw fit our needs wonderfully. Large open sites amongst the trees. A much enjoyed relief after days in the desert. Nice open wonderfully with plenty of shade. It was great to let off dog off the leash, far enough from the highway and no other campers in sight. We did see a family with a trailer try their luck further up, guessing they found a spot since they didn't come back down. No toilets or any kind of amenities, but peaceful, cool and shady. We did hear some wildlife in the night, possibly wolves (judging from the hotel we heard) so keep your pets inside at night.
