Update: ODNR has posted its 2020 winter camping amenities.
The Ohio Department of Natural Resources upgraded its website in the summer of 2020. Apparently they have yet to update the winter 2020 camping schedule and amenities. I have the 2019 information archived and thought it may be helpful to share screenshots.
Please note that I have heard from several sources that all campgrounds are requiring reservations this winter. I would highly suggest calling ahead this winter to confirm details.
Hoping that is helpful!
