The Line Hill Mound Area is a newer area for Butler County and is on the south side of the MetroPark with a separate entrance on Hamilton Middletown Road and also provides access to the 1.2-mile Earthworks Trail. It includes two main trails, the more forested Pond Trail and the Mound Trail which is more fields and scrub. The Mound Trail has a side trail leading to an Ancient Earthworks mound that sits in an old-growth forest. There is ample parking and a portable restroom unit in the adjacent practice field area (you will have to walk to from the parking area unless the gates to the practice fields are open). There is also a Historic Cemetery and two ponds near the entrance/parking lot. The Line Hill area appeals primarily to hikers, as there are no picnic tables or playgrounds. Use caution on trails during the wet season, as there are low areas that are muddy and slippery.

This hotspot was formerly known as Rentschler Forest Preserve and Miami and Erie Canal.

With almost 400 acres the Rentschler Forest MetroPark includes about a half-mile frontage along the Great Miami River, acres of woodland, remnants of the old Miami-Erie Canal, a prehistoric Indian earthwork, a reconstructed wetland, and ample opportunities for a wide variety of outdoor recreation activities. Many picnic sites, four covered picnic shelters, children’s play areas, soccer fields, a youth group camping area, and miles of hiking trails are found here. The Great Miami River Recreation Trail is accessible by the lower parking lot that connects to Hamilton. There will be an eventual extension through the park and along the river corridor to Middletown. New flush restrooms are also available thanks to a grant that enabled the Stone House to be re-purposed for this important amenity.
