This entrance is along Old State Road, just before you reach Cheshire Road. This campground is heavily used in the summer, but can be explored most other times of the year and usually has a good mix of land birds. If you take the first left just past the entrance station, this road will loop under the Cheshire causeway to a boat ramp with an expansive view of the middle reservoir that can produce waterfowl in the early fall or spring seasons.

Alum Creek rests in the midst of the fertile agricultural till plains and river valleys of Delaware County. In contrast to the surrounding farmlands, the park offers a diverse array of natural features. Cliffs of Ohio shale are notable in many areas, exposed as Alum Creek and other streams cut through underlying bedrock. The shale was formed as mud washed into the ancient sea which covered the area several hundred million years ago. The dark hue of the rock is due to the mixture of a carbonized plant material and mud that formed the shale.

The rich soils of Delaware County gave rise to a luxuriant beech-maple forest after the retreat of the glaciers about 12,000 years ago. That original forest has long since been cut but a healthy second-growth forest is preserved in the park. The woodlands harbor a variety of plant species and offer the interested observer beautiful displays of wildflowers and wildlife. Large-flowered trillium, wild geranium, bloodroot, and spring beauties carpet the forest floor. The forest is home to fox squirrel, woodchuck, rabbit, white-tail deer, and many other species of wildlife.
