Parking lot was open and plowed from previous snow fall. Under the new snow, the entire parking lot is pure ice! Be careful if heading there.

Fantastic campground, thank you. Small, few spots but right on the Posey river

This is a very nice park with non-electric shelters, restrooms, grills, a playground, great water views, and more gophers than I've ever seen anywhere else, lol. There is plenty of parking here, and a place to put in boats (and/or pick up people tubing down the river from Grandfather Falls). Very peaceful with lots of birdsongs and critters scurrying around. The bugs were not bad at all here. We...

There is plenty of parking here, and a place to put in boats (and/or pick up people tubing down the river from Grandfather Falls). Very peaceful with lots of birdsongs and critters scurrying around. The bugs were not bad at all here. We did see an active hornet nest in the shelter closer to the water, but they paid us no attention. Well worth visiting, this is a great place for many types of events! There was a massive amount of firework debris, so we spent the first hour cleaning it up before heading onto the Ice Age Trail segment that connects here. I have no idea if there are any Pokestops or gyms, as we had no signal whatsoever, but I'd have to imagine there are some here. This would be an ideal place to play (just mind the gopher holes, lol).

This has been a great two nights of camping here. What a great county park with the boat launch on top of it all. The vault bathrooms were very well-maintained and the park was free of trash and in very nice condition.
