The Adventuredome, formerly known as the Grand Slam Canyon, is a 5-acre indoor amusement park located at Circus Circus in Las Vegas. 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.
  You are not going to be bored with a bunch of lists on what you can ride, eat, or win at the Adventuredome in Circus Circus. All you need to know is that this is America's largest indoor theme park and it's hopped up on Vegas-style steroids. The colossal carnival-like atmosphere is more than five acres of thrills, chills and a crazy amount of fun for all ages.
