The Woodland Park Zoo, opened as a private zoo in 1889, is the oldest on the West Coast, and has been a leader in innovations in naturalistic zoo exhibits. The Seattle Aquarium has been open on the downtown waterfront since 1977. The Seattle Underground Tour, visiting places that existed before the Great Fire, is also popular. There are also many community centers for recreation, including Rainier Beach, Van Asselt, Rainier, and Jefferson south of the Ship Canal and Green Lake, Laurelhurst, and Loyal Heights north of the Canal.
