The central part of this vast park in western Tokyo is best explored by bicycle. There are about 120 bikes available for pre-schoolers and their parents to hire within the park (¥100-¥200 per hour), and when your child tires of pedalling, you can reward their hard work with a spot of sledging. There's a 17° artificial, turf-covered slope built into one of the park’s grassy knolls, and it's wide enough for at least a dozen sledges to race down at the same time. You can buy a sledge or borrow one of the park’s by queuing at the bottom of the slope. The park also houses the open-air branch of the Edo-Tokyo Museum.
