Buttonwood park is in a floodplane. When the Maumee River reaches flood stage (as frequently happens in spring and early summer), there are logs and sticks near the river. This is not a park with walking trails, but is best for fishing, boating and paddling access and has a large grass playfield. There are two Nature Preserves that are good for small children in Perrysburg both have trails. One is the W.W. Knight Nature Preserve, 29530 White Road, Perrysburg - there is a nature center, windows on wildlife, trails, gardens and ponds. The other is the Sawyer Quarry Nature Preserve 26940 Lime City Road, Perrysburg. There is a 1/2 mile loop trail that is handicapped accessible and there are stairs into the quarry for exploration.
