Adventuredome

Adventuredome is a five-acre indoor theme park under the pink glass dome behind Circus Circus, and it's still the only full amusement park in Las Vegas. Two legitimate roller coasters anchor it: Canyon Blaster, billed as the world's largest indoor double-loop, double-corkscrew coaster and running since August 1993, and El Loco, a compact 2014 machine with a 90-foot climb and two dive loops. Around them sit the rest of the park's dozen rides plus laser tag, an 18-hole mini golf course, a climbing wall, a VR room, a 4-D theater, and rows of midway games. Walking in costs nothing. Riding takes the all-day wristband: $60 for anyone 48 inches and taller, $30 for the junior tier under 48 inches, as of September 3, 2026.

The park opened in 1993 and doesn't hide it: worn edges, arcade din, and on any given day a ride or two down for maintenance. Climate control is the real headliner. When the Strip is pushing 110°F, this is the one place a kid can burn energy for hours without melting. It's built for families with children under 12 and for coaster fans collecting the two credits; adults without kids will see everything worth seeing in about an hour. Check the calendar before you commit, too. Monday through Thursday the dome opens at noon and shuts at 7 PM, and Circus Circus sits on the quiet north end of the Strip, a long walk from center-Strip resorts.
