Circus Circus - Adventuredome indoor amusement park under a dome

Circus Circus includes the Adventuredome, a five-acre indoor theme park housed beneath a pink glass-domed structure attached to the hotel. Adventuredome opened in 1993 and features roller coasters, thrill rides, and family attractions that operate year-round regardless of outside weather. Circus Circus itself originally opened in 1968 and its circus-themed architecture and interior décor emphasize family-oriented entertainment.
