The Amusement Park is the park that you see at the end of Park Road. Sylvain is the caretaker for the park and mentions to you that it used to be popular. This is also the place were Professor Layton's suspicions arise about the girl they keep on seeing around St. Mystere. A Ferris Wheel, controlled by Don Paolo, chases you here. This is good because it lets you see the entrance for the Tower Key.
