Circus Circus Las Vegas is a hotel and casino located on the northern Las Vegas Strip in Winchester, Nevada. It is owned and operated by Phil Ruffin. Circus Circus includes the largest permanent circus in the world. It features circus and trapeze acts, as well as carnival games, at its Carnival Midway. The resort also includes the Adventuredome, an indoor amusement park. Circus Circus was originally owned by Jay Sarno and Stanley Mallin. It opened without a hotel on October 18, 1968.
