Why dive here
With 131+ marine species recorded in the area - including dolphins, humpback whales, seals & sea lions, sea turtles and sperm whales - Hat Island offers some of Galápagos Islands's richest diving. Water ranges 23-28°C, warmest February, March, April.
Hat Island, or Isla Sombrero Chino, lives up to its name with a distinctive volcanic cone jutting from the sea. We've found the wall dives here offer a good chance to spot Galápagos sharks patrolling the deeper sections. It’s a decent drift dive, often with strong currents, so it’s best for divers comfortable in moving water. Keep an eye out for white-tipped reef sharks resting on the sandy bottom between volcanic rock formations.
Safety Notes
Strong currents typical this month (avg 36 cm/s). Good buoyancy control essential.
