The Lancaster County Central Park features diverse areas and trails including the Williamson Area with some very nice equestrian trails to the east and the Kiwanis Natural Area running through Mill Creek to the south. There are also some nice features like ball fields, a skate park, and a historic plantation.
There are several trails that run through the different areas, some of the main attractions being the CVA Trail on the north side of the park, and the Mill Creek Trail and Conestoga Trail System on the south end of the park. There are many connecting trails, so it's good to have a map of the area and choose your own adventure as you go. It is worth noting that many of the smaller trails are not well marked, so it can be a little easy to get turned around if you don't know the area that well.
There is parking at several entrances, but If you want to do a full park loop, it's best to start here at the parking area off Rockford Road and work your way south through the park.
