Gordon Rocks

Gordon Rocks — Galápagos Islands, Ecuador

Gordon Rocks is a collapsed volcanic crater sitting 10 km northeast of Santa Cruz Island, rising from the seafloor as a circular ring of pinnacles with a sandy arena inside. It is consistently ranked as one of the most challenging and most rewarding dives in the Galápagos — locally nicknamed 'The Washing Machine' for the current behaviour inside the ring.

What the Current Does

The Galápagos experiences powerful, multidirectional currents driven by the intersection of four major ocean currents. At Gordon Rocks, the ring of pinnacles channels and accelerates water in ways that are difficult to predict and impossible to fully control. The inside of the crater can be calm or it can be a swirling confusion of competing surge — hence the nickname.

Most dive briefings for Gordon Rocks include a frank assessment of conditions: it is a site where plans change based on what the current is doing at entry. Operators assess from the surface before committing. On some days, certain sections of the ring are simply not diveable.

The Hammerheads

When conditions are right — which they frequently are — the reward inside the ring is schooling scalloped hammerheads. The sharks use the crater as a cleaning station and aggregation point, circling at 20–30 meters in formations of dozens. From the rocky wall of the crater interior, you watch them turn in the blue — the unmistakable silhouette of the wide, flattened head, the slow, banking turns.

Galápagos sharks (Carcharhinus galapagensis) patrol the outer pinnacles. Sea lions hunt fish inside the crater and interact with divers in ways unique to Galápagos — approaching, retreating, looping. Sunfish (Mola mola) appear seasonally. Pacific green sea turtles are present on virtually every dive.
