This park has no amenities (no showers or laundry room), but the staff was helpful, and directed us to a nearby lavanderia that was quite nice. Parking was easy in the broad gravel lot (only a few small trees), and there is a cell tower right overhead, so coverage was excellent. Saturday night a nearby cantina kept us awake with loud music, but it was quiet the next night we were here. We would overnight at this park again. We camped here in a Travel Trailer.
