Current-swept seamounts at Darwin and Wolf Islands assemble scalloped hammerhead schools that can number in the hundreds, often sharing the blue with whale sharks, Galápagos sharks, and bottlenose dolphins on liveaboard-only itineraries. This is expedition diving at its most demanding and most rewarding. The Humboldt-cooled window from June through September concentrates the densest hammerhead traffic of the year.

Up to 98% sighting chance in Darwin & Wolf Islands (Galapagos, Ecuador). Best months: July, August, September.
June through September is peak, when cooler Humboldt currents bring the largest scalloped hammerhead schools numbering in the hundreds.
No. These are advanced current dives on remote seamounts for experienced liveaboard divers only.
Eight-day liveaboard itineraries typically run 4,500 to 7,500 US dollars per person (2026 prices), excluding flights to Ecuador.
Whale sharks, Galápagos sharks, silky sharks, and bottlenose dolphins frequently share the same blue-water drifts.
Near-certain on most summer liveaboard weeks, though daily conditions and current strength still vary.
