Silverwood Theme Park is an amusement park located in northern Idaho, United States, near the town of Coeur d'Alene, and just 47 miles from Spokane, Washington on U.S. Route 95. Owner Gary Norton opened the park in June 20, 1988 and originally included a few carnival rides, a main street with shops, and an authentic steam train that traveled in a 30-minute loop around the owner's property. From 1973 to 1988, the land with an airstrip and other attractions was operated as the Henley Aerodrome, named after the family whom Norton bought it from in 1981.
As the years went by, Silverwood has grown in size and popularity. In 2003, an adjacent waterpark named Boulder Beach Water Park opened and is included with admission to Silverwood. In 2009 Silverwood began an annual Halloween event during the month of October called Scarywood.
Garfield and Odie are the official mascots of Silverwood Theme Park.
Today Silverwood is the largest theme and water park in the American Northwest on 413-acre (1,670,000 m2) and boasting more than 65 rides, slides, shows and attractions.
Gary Norton buys Henley Aerodrome from the heirs of the Henley estate and lengthening and other improvements are done to the airstrip. Hangar is turned into an air museum. Old English type inn is built.
Norton outbids Disney and others for a narrow-gauge locomotive for use at the Aerodrome.
Silverwood opens to the public with the 3 ft (914 mm)narrow gauge Silverwood Central Railway, Main Street shops (including a movie theater), and Country Carnival, which includes a small assortment of carnival rides
In 2009, Silverwood opened Scarywood Haunted Nights, a nighttime fright fest filled with scare zones and mazes. In 2010, Scarywood returned on a larger, grander scale with more to do. The main attractions for Scarywood are the Terror Canyon Trail, a maze and walkthrough built in the Thunder Canyon ride flume; Blood Bayou, an indoor haunted attraction; the Zombiewood Express, the park's train ride transformed into a haunt and show in the woods where Nick Norton and Elvis hunt zombies; as well as the Timber Terror: Backwards.
