I just phoned Catalina State Park....they have no sites with sewers, but they do have a dump station.
It is really a nice park and we think well located, of course, maybe because we live here in OV.
There is a private park on up State Highway 77 (known also as Oracle Road) named the Wishing Well.
The phone # of The Wishing Well Trailer Court (clue there
is 520-825-3361 and it is located at 16100 N. Oracle Road.
It truly is a trailer court but it has full hook-ups. Brenda and I would feel comfortable there; it is not fancy but we like it.
