You can access the Walnut Creek Fields from the nearby Groveport municipal golf course or from the intersection of the Pin Oak and Sweetgum Trails. The creek is pretty low, so it can be crossed there or by walking around to the bridges in the golf course.

Walnut Woods features 1,098 acres of woodlands and fields, bordered by Walnut Creek to the north. The Tall Pines Area features dramatic stands of pines and sweetgum trees, and the Buckeye Area has long rows of old nursery trees such as serviceberry, crab apple and red maples. The park also features restored wetlands and vernal pools.
