An arena specially designed for use by skateboarders comprises an oval shaped bowl having relatively steeply curved sidewalls and a long gradually inclined ramp leading to each longitudinal end thereof. An oval shaped mound having an elevation on the order of one-half that of the top of the ramps at the longitudinal ends of the bowl is integrally formed on the floor in the center of the bowl. The curved sidewall portions opposite the central mound extend upwardly and inwardly to an elevation which is higher than the longitudinal ends of the bowl. Also located at each longitudinal end of the bowl is a truncated cone shaped ball pit which is mounted on the front wall of an elevated portion of a building structure such that it overhangs the inclined surface on the upper end of the ramp.
