The world’s largest indoor theme park, which features popular Marvel and Cartoon Network-branded rides, has opened in Dubai. The 1.5 million square-foot indoor amusement park offers visitors and residents an air-conditioned respite from the soaring summer temperatures outside.

The IMG World of Adventure park, which spans 140,000 square meters, attracted around 3,000 visitors on its first day in Dubai. It hopes to attract 30,000 visitors daily with its Marvel and Cartoon Network zones, a Lost Valley Dinosaur zone and a “Haunted Hotel” along its indoor boulevard.

Among the rides on offer are a spinning Spider Man roller coaster and a Powerpuff Girls ride. Along with its 22 rides and attractions, the park offers visitors 25 retail outlets and 28 food and beverage outlets that are expected to contribute to nearly a quarter of the park’s overall revenues.

The adventure park is one of two major theme parks opening this year in Dubai, part of an effort to attract 20 million tourists annually by 2020, when it hosts the World Expo.
