Universal Orlando Resort officially opens its third and newest theme park, Epic Universe, on May 22. CNN takes a look inside the park and its four worlds.

The new Epic Universe in Florida marks the first new major theme park in the United States in nearly a quarter century, lives up to the hype created during the years of buildup and ups the ante in Universal’s crosstown showdown with rival Walt Disney World.

Epic Universe is believed to be the largest theme park in the world and estimated to have cost up to $7.7 billion to build.
