You can walk around Universal CityWalk without paying for admission, but you cannot enter the actual theme parks (Universal Studios or Islands of Adventure) for free. CityWalk is a massive dining, shopping, and entertainment district that serves as the "gateway" to the parks. While there is no ticket required to wander through CityWalk, take in the neon lights, and visit stores like the Universal Studios Store or the Toothsome Chocolate Emporium, you will typically have to pay for parking if you arrive by car (usually around $30, though it is often free after 6:00 PM). To step foot inside the actual theme parks, see the Wizarding World of Harry Potter, or ride the attractions, a valid theme park ticket or annual pass is mandatory. Security checkpoints and ticket turnstiles separate the free-to-access CityWalk from the paid park areas.
