Come check out the sport of Goal ball! Goal ball is the most popular team sport for the blind and visually impaired and is an official Paralympic sport. Participants wear blacked-out goggles and two teams of three players compete across a volleyball sized court. The object of the game is to roll a basketball sized ball with bells inside, across your opponent’s goal line. The defensive team listens for the oncoming ball and attempt to stop the ball crossing their goal line by using their bodies to block.
