Recently stayed for one night camping here in late December 2023. I'll preface this by saying I did enjoy the atmosphere! The camping amenities leave a bit to be desired.
We stayed in spot 9 which was spacious and oddly wide. We use a converted travel trailer, so we had plenty of room. Fire pits are located close to the road. Spots are all dirt and a bit uneven. Some large RVs had trouble parking and leveling. The spot next to ours did not have a working water spigot, so they used ours which had a double spigot (one of which we didn't need). We didn't experience it, but we heard about 3 different campsites temporarily lose power around 9 PM. Not many camp sites at all so relatively quiet at night and early morning.
The bathrooms were rough. A large industrial sized ventilation fan was constantly running in both restrooms (*all* the time... Loudly). The camp bathrooms are the same as the public spring bathrooms, so they were a bit dirty by end of day even in winter. The bathrooms were not heated. There was a shower curtain hanging in entry way for each bathroom entry (although there is a regular wooden door - it is just always propped open). Hot water worked well. Sinks have a slab of wood running around foot above to hold toiletries as sink itself is just a pedestal.
The road into the springs and parking area is all dirt and a bit bumpy. No firewood sold in the park at this time.
Lots of barriers around currently (wooden stakes with black tarps) to I believe help with run off. Huge area around the springs is sectioned off as the entire wooden walkway and dock that used to be there is all gone. Spring itself looks pretty beyond that though. They rent kayaks and canoes (put pictures of their pricing noted in December 2023). Had several picnic pavilions not far from spring. Not many benches around near spring itself. No playground. Dogs not allowed near the spring area.
Has potential to be a wonderful state park if a little investment is put into the sites.
