The park has natural-looking plantings and landforms, having been almost entirely landscaped when built in the 1850s and 1860s.[5][6] It has eight lakes and ponds that were created artificially by damming natural seeps and flows.[7] There are several wooded sections, lawns, meadows, and minor grassy areas. There are 21 children's playgrounds,[8] and 6.1 miles (9.8 km) of drives.[2][9]
