This enormous park was enclosed in 1637 for use as a royal hunting ground—like practically all other London parks. Unlike the others, however, Richmond Park still has wild red and fallow deer roaming its 2,360 acres (that's three times the size of New York's Central Park) of grassland and heath. Its ancient oaks are among the last remnants of the vast, wild forests that once encroached on London in medieval times. The Isabella Plantation (near the Ham Gate entrance) is an enchanting and colorful woodland garden, first laid out in 1831. There's a splendid, protected view of St. Paul's Cathedral from King Henry VIII's Mound, the highest point in the park. Find it and you have a piece of magic in your sights. The park is also home to White Lodge, a 1727 hunting lodge that now houses the Royal Ballet School.
