This park has a small animal farm, with horses, chickens, goats, pigs, and cows. It also has a lake that is stocked regularly that you can fish in.
They also have BBQ pits as well as shelters that you can have a group event at.
They are only open though during the spring, summer and fall, so don't bother going in the winter.
Again, it's a small farm, so don't expect a ton of excitement here, but it is free and the kids will love it!
Plenty of parking.
