A coaster having a first vertical segment connected to a parabolic segment that is connected to a second vertical segment. The carrier is raised up the first vertical segment by any means that is well known in the art. The carrier descends under the force of gravity and may either oscillate or be braked. Optionally, the track rolls about its longitudinal axis during the first vertical segment. The seats in the carrier are preferably in a tilted position so that when the carrier is vertical with the seats facing downward, the participants actually tilt forward past vertical.
