I stopped here for lunch. You're in the desert, so hot during the day. There are some trees for shade, especially for the campsites along Yaqui Pass Road. All sites have lattice-work shelters for shade over the picnic tables. Water is listed as non-potable at all faucets. Besides campsites, there are one-room cabins for rent. $35/night for the campsites is a lot, but that is state park practice in CA. National Forest campgrounds are cheaper.
