Jurassic Park is a Steven Spielberg film franchise about a theme park with real dinosaurs. Jurassic Park at Universal's Islands of Adventure is a real theme park (or at least a section of one) with fictitious dinosaurs. The iconic Visitor's Center from the original film is one of the first things guests will see across the lagoon after walking through Port of Entry. The amount of space within Jurassic Park is deceptively large, and the entire area is completely immersive as you walk through it (except where Harry Potter's Hogwarts intrusively pokes above the trees).

There are two main entrances into this island, one coming from Toon Lagoon via Skull Island, and another from the Wizarding World of Harry Potter. A third way in is the bridge between Lost Continent and Jurassic Park, which allows guests to bypass Hogsmeade on busy days.
