The Mercer Meadows- Rosedale Lake segment of the LHT travels through Rosedale Park district and provides a scenic and tranquil setting for picnics, walks, and other outdoor recreation. This area is a mix of woodland and fields and also provides easy access to the Stony Brook, Willow Pond, and Rosedale Lake.
The LHT continues on the north side of Blackwell Road along the driveway access to Hunt House.

The LHT continues north for 0.45 miles then turns west as it rounds Willow Pond. Continuing west, the trail passes along the north side of Rosedale Lake, the parking area, and dog park to Federal City Road. After crossing Federal City Road, the LHT travels along open meadows and through the Mercer Meadows Equestrian Center then returns to Federal City Road. The LHT continues onto Old Mill Road crossing the Stony Brook and then leaves the roadway on a gravel path until intersecting with Pennington Rocky Hill Road.

The historic Hunt House, located on the grounds of Rosedale Park was originally built in the 1700s by Noah Hunt, a prominent early resident of Hopewell who worked the once prosperous farm. The Hunt House now serves as the offices of the Mercer County Park Commission.

Rosedale Lake is the largest water feature along the LHT. It is a manmade lake formed in the 1960s when the Mercer County Park Commission acquired the Blackwell Farm, dammed a small tributary of Stony Brook and created the water feature for recreational boating and fishing.

Near Federal City Road and Old Mill Road is the Fish Farmstead, also known as the Adams House, which dates to the early 19th century. The house is a typical example of an L-shape farmhouse, a standard type that was found throughout the region and would have housed a farming family and several farmhands. The farm now serves as the County’s Equestrian Center, and the house is occupied by park staff.

The Mercer Meadows- Rosedale segment is owned and managed by Mercer County.
