Adventuredome

About

Adventuredome (formerly Grand Slam Canyon) is a 5-acre (2 ha) indoor amusement park at Circus Circus in Winchester, Nevada on the Las Vegas Strip. It is owned by Phil Ruffin. It is contained within a large glass dome, and offers various rides and attractions including the Canyon Blaster and El Loco roller coasters, a rock climbing wall, an 18-hole miniature golf course, a video game arcade, and carnival-type games. Because the park is enclosed, it is unaffected by weather, unlike most theme parks, and is open year-round. Every October from 2003 until 2017, the Adventuredome was turned into the Halloween-themed Fright Dome.

The theme park opened as Grand Slam Canyon on August 23, 1993, in the west parking lot of the hotel. It sits on a reinforced 18" thick deck elevated 18 feet (5 m) above ground. The dome itself consists of over 350,000 sq ft (33,000 m2) of pink tinted, insulated glass over a teal green space frame (to minimize structural poles inside). Each pane of glass weighs approximately 300 lb (140 kg). After customer feedback, the park was closed for 45 days in 1994 to add new attractions. Grand Slam Canyon was renamed the Adventuredome in 1997.
