The largest park in central Tokyo is just across the Edogawa River from Tokyo Disney Resort. Opened in 1989, the park was built on reclaimed land and developed in an effort to restore and preserve natural Tokyo Bay habitat. The park offers a nice break from the surrounding cityscapes and has a number of walking trails that crisscross the gardens, lawns and beaches. In addition, the park features an aquarium, two cafes, a Ferris wheel, a seabird sanctuary, and the Crystal View observatory. Mt Fuji is viewable on a clear day from the Ferris Wheel and the observatory. There are a number of ferries (waterbuses) that serve the park though these services are infrequent and announced in advance on the Tokyo Parks Waterbus page.
