When examining the geography of the Jurassic Park franchise, the third installment diverges significantly from its predecessors by transporting the chaos to a remote and hostile environment. The question of what island Jurassic Park 3 takes place on is central to understanding the film's distinct tone and survivalist narrative, moving away from the theme park spectacle to a primal struggle for escape.
The Location: Site B
Jurassic Park III is set on a location known as "Site B," a designation used by InGen to refer to the secondary island where they cloned dinosaurs for eventual relocation to the main park. While the specific name of the island is never explicitly stated in the film, production materials and supplementary media confirm the setting is "Site B." This island serves as the testing ground and nursery for the dinosaurs, a fact that explains the dense population and variety of species encountered by the human characters.
Isla Sorna: The Official Designation
The island is officially named Isla Sorna in the extended Jurassic Park universe, a name that has been solidified through novels, video games, and official park diagrams. Isla Sorna translates to "Searing Island" or "Island of the Carnivores," a fitting name for a landmass dominated by predatory dinosaurs. Its location in the Costa Rican sea, far from the main tourist destination of Isla Nublar, makes it the perfect secretive facility for genetic experimentation and creature cultivation away from public scrutiny.
The Environment and Its Dangers
The environment of Isla Sorna is depicted as a lush, tropical jungle interspersed with massive grasslands and imposing rocky cliffs. This diverse landscape creates a visually stunning backdrop that is both beautiful and terrifying, as the characters navigate through dense foliage while being constantly pursued by the island's inhabitants. The film leverages this setting to maximize tension, using the thick vegetation to obscure threats and create a constant sense of paranoia and vulnerability.
The island's geography is a key plot driver, forcing the group into specific corridors and valleys.
Massive herds of dinosaurs, such as the Parasaurolophus, are shown migrating across the open plains.
The presence of large predators like the Spinosaurus and Velociraptors establishes the island as a true predator's domain.
The wreckage of the InGen compound provides a tangible link to the corporate ambition that created the island's ecosystem.
Contrast with Previous Installments
Unlike the first film, which took place on the fully realized theme park of Isla Nublar, the third film strips away the illusion of control. Isla Nublar was a functioning tourist destination with infrastructure and order, whereas Isla Sorna is a raw, untamed wilderness where the dinosaurs are the undisputed rulers. This shift is crucial to the film's narrative, removing the safety net of fences and security teams and placing ordinary humans directly in the food chain.
The Narrative Significance of the Location
Setting the story on Isla Sorna allows the film to explore themes of nature reclaiming space and the futility of attempting to weaponize prehistoric life. The absence of human authority figures emphasizes the island's sovereignty, suggesting that the dinosaurs have not only survived but thrived in the absence of their creators. The location is not just a backdrop but an active character that shapes the desperate and primal struggle for survival.
Legacy and Canonical Placement
Following the events of Jurassic Park III, the narrative timeline shifts, but the island remains a critical location in the lore of the series. Isla Sorna's depiction as a breeding ground raises questions about the ethics of InGen's operations and the potential consequences of genetic manipulation. The island serves as a grim reminder of the chaos that ensued when science overreached, cementing its place as a pivotal setting in the ongoing saga of Jurassic Park.
