Dive at Darwin Island, home to the majestic whale shark. These giants are frequently sighted here, with most being pregnant females. In the afternoon, head to Wolf Island, where strong currents attract schooling hammerheads, Galapagos sharks, blacktips, and silky sharks. The island's rocky walls and slopes are teeming with eagle rays, large schools of fish, and two species of sea turtles. A night dive option is available depending on conditions.
