Silverwood Theme Park is an amusement park located in the city of Athol in northern Idaho, United States, near the town of Coeur d'Alene, approximately from Spokane, Washington on US 95. Owner Gary Norton opened the park on June 20, 1988. Originally, the park included a small assortment of carnival rides, a "main street" with shops and eateries, and an authentic steam train that traveled in a 30-minute loop around the owner's property. From 1973 to 1988, the land, along with a fully functioning airstrip, was operated as the Henley Aerodrome, named after the family whom Norton bought it from in 1981.
