High Park is a municipal park in Toronto, Ontario, Canada. It spans 161 hectares (400 acres), and is a mixed recreational and natural park, with sporting facilities, cultural facilities, educational facilities, gardens, playgrounds and a zoo. One third of the park remains in a natural state, with a rare oak savannah ecology. High Park was opened to the public in 1876 and is based on a bequest of land from John George Howard to the City of Toronto. While Rouge Park is the city's largest park, High Park is the largest park entirely within the city, as Rouge Park extends into the neighbouring cities of Markham and Pickering.
