I stayed at this campground because they hosted a wedding I attended. I chose to stay in a cabin, which was pretty pricy for what it was. for $175, it was a basic cabin with a queen bed and 2 twin bunk-beds, a very small bathroom with a toilet and shower, and a small kitchenette with a microwave, sink, and mini-fridge. The cabin was somewhat dirty - dust on the floor and spider webs in the corner. It had no bed linens, or towels, and the bathroom didn't even have a mirror.
There is a "lake" (more of a large pond) on the property, with fishing, and large inflatables to play on in the summer. There is also a disc golf course. The nearby town Lithopolis is cute, with some local coffee and dining, as well as antique shops.
The campground itself is beautiful - nestled in the forest, it feels very remote. Each campsite has a ~10x10 level tent pad, a nice picnic table & fire box. There's a mix of more open campsites (if you want a few next to each other for a larger group) or a little more secluded. If you want really secluded - there is an upper loop that the road is closed, but you can hike your stuff up to if you'd like. The bathrooms were nice & clean, and there are spigots for drinking water. The park also features a lovely little loop trail that follows along a stream, which was nice & cool despite the fact that I visited in late July. The last neat feature is a small and very old cemetery above campsite 10
The nearby town Hot Springs is about 8 minutes away and features everything you would need - food, a few small convenience stores, and gas.
The negative bit is I got absolutely eaten alive by chiggers at this campsite, so make sure you apply bug spray!
Overall good campsite on South Bass Island. It's close to Put in Bay - famous for it's bar scene. If you're good at trekking, everything on the island is walking distance, but if you can bring it a bike would make for much quicker trips. There are also a number of taxi services or golf cart rentals available.
The sites are very small, but have very nice views of the lake. It stormed while I was there and the winds got strong, so make sure your tent is sturdy, or choose an in-land campsite.
