Gordon Rocks is widely regarded as one of the most thrilling dive sites in the Galápagos Islands — and for good reason. Located just a short boat ride from Puerto Ayora on Santa Cruz Island, this submerged volcanic crater is home to enormous schools of scalloped hammerhead sharks, making it a bucket-list destination for experienced divers worldwide.
What to Expect
The dive site sits about 40 minutes by speedboat from Itabaca Channel. Once you arrive, you'll gear up and descend along the crater walls, where strong currents bring nutrient-rich waters that attract an incredible concentration of marine life. Visibility varies between 10 and 20 metres depending on the season, but even on murkier days the sharks appear in impressive numbers.
Most dives reach depths of 18–30 metres. You'll typically complete two dives during the trip, with a surface interval spent on the boat enjoying snacks and watching the surrounding seabird colonies on the rocky outcrops.
The Hammerheads
The main attraction is undeniable: large schools of scalloped hammerhead sharks cruising through the blue. These magnificent creatures often swim in formations of 20 to 50 individuals, though groups exceeding 100 have been reported during peak season (June–November, when the Humboldt Current brings cooler, plankton-rich water).
Beyond hammerheads, keep your eyes open for Galápagos sharks, white-tip reef sharks, eagle rays, golden rays, sea turtles, moray eels, and the occasional Mola Mola (ocean sunfish) during the cold season.
Practical Information
Gordon Rocks is classified as an advanced dive site. Most operators require at least 30 logged dives and an Advanced Open Water certification. The currents can be strong and unpredictable, so good buoyancy control is essential.
Tours typically depart early in the morning (around 7:00 AM) and return by early afternoon. The price generally ranges from $180 to $320 per person depending on the operator and whether equipment rental is included.
What's included: Two guided dives, full equipment (if renting), wetsuit, snacks and water, boat transfer, dive guide.
What to bring: Your certification card, personal dive computer if you have one, seasickness medication (the crossing can be choppy), a warm layer for the boat ride, and a waterproof camera if you want to capture the experience.
Best Time to Visit
The cold season (June–November) offers the highest shark concentrations and best chances of seeing Mola Mola, though water temperatures drop to 17–21°C. The warm season (December–May) brings warmer water (22–27°C), better visibility, and calmer seas but somewhat fewer hammerheads.
Why Gordon Rocks is Special
What makes this site truly exceptional isn't just the sharks — it's the raw, untamed nature of the dive. Unlike many popular dive destinations worldwide, Gordon Rocks has no permanent moorings, no underwater structures, and no crowds. It's just you, the ocean, and some of the most extraordinary marine life on the planet.
For divers visiting the Galápagos, Gordon Rocks is simply not to be missed.
