Gran Susto (Big Scare) Dive Site — Costa Rica

About Gran Susto (Big Scare)

The most famous dive site at the Bat Islands (Islas Murciélago), known worldwide for close encounters with massive bull sharks up to 3.5m. Divers descend rapidly to 30m along a rocky pinnacle where bull sharks patrol in the blue. Strong currents and limited visibility make this a thrilling, adrenaline-pumping dive for experienced divers only.
