Abstract: An apparatus which closely simulates actual snowboarding is provided. The snowboard simulator apparatus includes a board member with a curved or convex lower surface, a pair of stop members positioned on the longitudinal edges of the board, a pair of cross-rails positioned perpendicularly relative to the stop members and a roller member having a pair of guide slots for engaging with the cross-rails. The rolling travel of the roller member is limited by the stop members while the positioning of the roller member on the lower surface of the board member is controlled by the engagement of the cross-rails with guide slots. The apparatus generates a front-to-back action for the user which closely simulates actual snowboarding. The apparatus is also capable of simulating a pivot turn maneuver as experienced in real snowboarding.
