Woodland Mound is a nice park. It features many of the same amenities as other parks in Hamilton County, OH. I differ with the "out and back" description given on AllTrails. There is a continuous paved trail that spans about 1.3 miles. From the paved loop are several gravel out and back trails that are .6 to .9 miles in length. I did two of the side trails and completed the paved circuit three times to meet my workout needs.
This is a nice trail system with a central, paved, bike/hike loop of 3.5 miles. You can extend this by a couple miles by veering off on a few "there and back" side trails that follow very well marked and maintained dirt trails.
