Take a ride in the crystal blue waters of the Alpine water slide at Magic Mountain in Big Bear! Turning and banking on the way to the 3 1/2' deep pool of inviting water. When you are done, relax with family and friends on the poolside redwood deck. The double water slide operates during the summer months, taking riders down two twisting and turning flumes filled with refreshing, cool water, before dumping them with a splash into the heated pool at the bottom.
