World's End is a 251-acre (1 km²) park and conservation area located on a peninsula in Hingham, Massachusetts. The peninsula is bordered by the Weir River to the North and East and Hingham Harbor (part of Hingham Bay, and Boston Harbor) to the West. The land is composed of four drumlins (Pine Hill, Planter's Hill, and the double drumlins of World's End proper) harboring tree groves interspersed with fields attractive to butterflies and grassland-nesting birds, and offers 4.5 miles of walking paths with views of the Boston skyline.
