The Rosedale Park district provides a scenic and tranquil setting for picnics, walks, and other outdoor recreation.  A system of trails, including a section of the Lawrence-Hopewell Trail, passes through the woodland and fields of the district, providing easy access to the Stony Brook, Willow Pond, and Rosedale Lake.  Fishing is a popular pastime in these three bodies of water, which are also an attraction for wildlife such as Bald Eagles, Osprey, and many varieties of waterfowl.

Rosedale Park is the only district of Mercer Meadows enhanced to provide both passive and active recreational opportunities, and near the main entrance on Federal City Road are a baseball diamond, an off-leash dog park, picnic pavilions, playgrounds, volleyball net, and several acres of open lawns.
