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 47 mi (76 km) 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.

Over the years, Silverwood has grown in both size and popularity, transforming from a small local amusement park to a regional theme park destination. In 2003, an adjacent waterpark named Boulder Beach Water Park was opened. Entrance to Boulder Beach is included with admission to Silverwood. In 2009, Silverwood began an annual Halloween event called Scarywood, held during evenings in the month of October. Comic characters Garfield and Odie are the official mascots of the 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 70 rides, slides, shows and attractions. It is the northernmost theme Park in the United States. In 2019, Silverwood co-hosted (along with Rocky Mountain Construction) the Golden Ticket Awards.

Scarywood Haunted Nights

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 include: Blood Bayou, an indoor haunted attraction; Planet Zombie, another outdoor haunt ; several scare zones and other walk through as well as the Timber Terror: Backwards. In 2020, due to concerns with Covid-19, Scarywood was cancelled. The park did remain open weekends in October without the scary theming though.

Current Silverwood Theme Park rides

Roller coasters

First drop on the Tremors roller coaster
Ride Opened Manufacturer Description
Aftershock 2008 Vekoma An inverted roller coaster, relocated from Six Flags Great America where it was known as Déjà Vu. Riders are arranged in a 'V' shaped seating configuration below the track where their legs dangle. The coaster is the third generation of Boomerang, known as the Giant Inverted Boomerang.
Corkscrew 1990 Arrow Development A steel roller coaster, relocated from Knott's Berry Farm in 1990. When Corkscrew first opened in 1975 at Knott's Berry Farm, it achieved two things of historical significance. Corkscrew was not only the first modern inverting coaster in the world, but it also was the first roller coaster to take riders upside down twice.
Krazy Koaster 2014 SBF/VISA Children's spinning coaster A children's spinning roller coaster with a figure-8 layout. The cars of the train spin freely based on weight distribution.
Stunt Pilot 2021 Rocky Mountain Construction A Single Rail coaster, a clone of California's Great America's RailBlazer and a mirrored image of Six Flags Fiesta Texas's Wonder Woman Golden Lasso Coaster.
Timber Terror 1996 Custom Coasters International A wooden roller coaster with a classic out-and-back layout. The ride uses trains from Philadelphia Toboggan Coasters. Formerly known as the Grizzly until a potential lawsuit from the former Paramount Parks prompted the name change. Since 2010, the train has been reversed for the park's Scarywood Haunted Nights events every October.
Tiny Toot 1998 Zamperla A powered roller coaster themed to a mine train for young children and parents as well. Ride is driven by a rear wheel that runs along a central tread that runs along the middle of the track. Ride has an oval layout and runs over a small manmade creek.
Tremors 1999 Custom Coasters International A wooden roller coaster with a twister layout that uses the terrain to its advantage. It features four tunnels, the first of which goes under the ride's gift shop. The coaster uses rolling stock from the Philadelphia Toboggan Coasters company. In 2010, the ride was the first to receive "topper track," a new track system designed by Rocky Mountain Construction of Hayden, Idaho. The new system, similar to the company's new Iron Horse I-Box track system is designed to cut down on track maintenance, as well as daily wear and tear. Rocky Mountain Construction had previously assisted with the initial construction of the ride.
