As an alternative to the NPS campground across the road, this mobile home park has some full hookup RV spots in the rear of the mobile home park next to the laundry/restrooms. Note that the restrooms/showers are closed but laundry is open. Office staff said campers from the NPS campground can use the laundry. Cost for RV as of Feb 2022 was only $29.38 for full hookups. Only about 9-10 sites are available for RVs and reservations are required either online or in the office upstairs at the Callville Bay Store. No tents, no open fires, no wifi. However, cell signal is very good on Verizon, TMobile and ATT due to the cell antennas by the NPS water tanks above the NPS campground.
