A facility including an inclined plane for sliding for which snow is used, a snow producing apparatus for producing snow from water and supplying the snow to the facility, and an air jet apparatus for forming an air roof by air flow so that the air roof covers space over the facility, are provided. The air roof covers space over the facility for which artificial snow is used, thus making the building of a roof and the like unnecessary and lowering building costs. The inside of the facility is opened to the fresh air by stopping the supply of air for forming the air roof, which makes special equipment for measures against exhaust gas unnecessary.
