Located in the heart of Tokyo, and part of the Tokyo Dome complex, LaQua is easily accessible by bus or subway (Suidobashi station). As space is notoriously limited in Tokyo, the park takes up a pretty small area, but manages to use the available space well. It's completely free to enter, and rides can be paid for individually. An all day, all inclusive pass will cost you 4,000 Yen (around 20 pounds). LaQua doesn't really have much of an "amusement park" atmosphere, being very much a city park, but thrillseekers will not be disapointed here.
