About this spot
Big Scare lives up to its name. This advanced dive site sits within the Área de Conservación Guanacaste, a protected marine zone off Costa Rica's northern Pacific coast. Depths run 18 to 35 meters, making it a site for experienced divers who are comfortable with deep water and strong current conditions. The name hints at what you'll encounter: this is a site built for pelagic action and larger marine life. The Bat Islands themselves are remote and rarely visited, which keeps the ecosystem relatively untouched. Big Scare's reputation draws divers looking for that edge—encounters with sharks, rays, and other open-water species are common. The protected status of the area reinforces its appeal for serious divers who want to dive healthy reefs away from crowds. Access requires a boat from the mainland and advance planning. Currents can be strong, so this dive is not for beginners or intermediate divers testing their limits. Weather and sea conditions dictate when trips run, so flexibility is essential. Local dive operators familiar with the Bat Islands will know the best conditions and how to position for encounters.
