Adventuredome

Adventuredome (formerly Grand Slam Canyon) is a 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 above ground. The dome itself consists of over of pink tinted, insulated glass over a teal green space frame (to minimize structural poles inside). Each pane of glass weighs approximately . 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.
