The Adventuredome, formerly known as the Grand Slam Canyon, is a 5acre indoor amusement park located at Circus Circus in Las Vegas, Nevada on the Las Vegas Strip. The park is connected to the hotel inside a large glass dome, and currently offers 25 rides and attractions including the Canyon Blaster roller coaster, rock climbing wall, 18-hole miniature golf course, an arcade, clown shows, Xtreme Zone, Pikes Pass, Virtual Reality Zone, Midway Games, and carnival-type games. Because the park is enclosed, it is not affected by cold, rainy, or windy weather, unlike most theme parks, and is open year-round. Every October since 2003, the Adventuredome is changed to Fright Dome as a Halloween-themed theme park.The Adventuredome opened on August 23, 1993 in the west parking lot of the hotel. It sits on a reinforced 18" thick deck elevated 18ft above ground. The dome itself consists of over 350000sqft of pink tinted, insulated glass over a teal green space frame (to minimize structural poles inside). Each pane of glass weighs approximately 300lb.Previous owner of Adventuredome was Mandalay Resort Group, formerly known as Circus Circus Enterprises (1993–2005)
