Straddling the equator some 600 miles off the coast of Ecuador, the Galapagos Islands are one of the most biodiverse and geologically unique places you can visit. This remote volcanic archipelago, made up of 13 main islands and dozens of smaller islets, is a protected haven where spectacular wildlife reigns supreme both above and below the surface.
Its remote location means that some of the ocean’s most curious, quirky, and unique species thrive here, creating thrilling and varied dive sites. Most diving is done by liveaboard, but land-based dive trips are available from Santa Cruz, San Cristóbal, and Isabela.
What makes diving in the Galapagos so good?
What makes the Galapagos such a legendary dive destination is not only the size of the marine life, but the sheer volume of it. From hammerhead sharks and massive schools of jacks to marine iguanas and penguins, the underwater encounters here are unmatched.
In this truly wild place, divers will experience powerful currents, dramatic volcanic topography, and water temperatures that can swing between tropical and temperate—all in a single dive.
With the opportunity to drift through hundreds of schooling hammerheads, spot whale sharks and mola molas in season, and then turn to find a seahorse clinging to a sponge, the Galapagos truly belong on every diver’s bucket list.
Northern Galapagos
Darwin’s Columns (formerly Arch)
Region: Northern Galapagos
Galapagos’ crown jewel—Darwin’s Columns (formerly Arch)—is iconic for a reason. Located at the northernmost point of the archipelago, within the Galapagos Marine Reserve, this remote site is only accessible via liveaboard.
Experienced divers should expect strong currents, surges, and deep drop-offs. Visibility ranges from 40 to 100 feet (12–30 m), and diving is always done from zodiacs with negative entries and quick descents.
Things to See:
Darwin’s Columns is a pelagic paradise, with the sheer size and number of marine creatures truly mind-boggling. Divers will tuck themselves into small outcroppings along a sloping wall to watch while massive schools of hammerhead sharks cruise by, interrupted only by the occasional whale shark.
Schools of yellowfin tuna dart around, adding another dynamic to this phenomenal dive site. Other visitors may include curious dolphins, moray eels, and dozens of sea turtles.
Highlights:
- Massive schools of hammerhead sharks
- Whale shark sightings (seasonal)
- Fast, thrilling currents
Type: Drift, deep, big animals
Skill level: Advanced
Access: Liveaboard only
Wolf Island
Named after German geologist Theodor Wolf, who extensively studied the Galapagos Islands, Wolf Island offers multiple dive sites around its perimeter and shares the same remote, liveaboard-only exclusivity as Darwin.
The waters here are wild—expect strong currents, surge, and deep dives. Visibility varies, but marine action is consistent. Water temperatures can drop with thermoclines, so bring exposure protection.
Things to See:
Wolf is all about the sharks—scalloped hammerheads, Galapagos sharks, silky sharks, and sometimes tiger sharks. You may also spot eagle rays gliding in formation, sea lions zipping through schools of fish, and the rare red-lipped batfish on the sandy bottom.
Highlights:
- Wall-to-wall hammerheads
- Galapagos and silky sharks
- Massive schools of fish
Type: Drift, deep, shark
Skill level: Advanced
Access: Liveaboard only
Western Galapagos
Punta Vicente Roca
Region: Western Isabela Island
Tucked into a protected cove on Isabela’s northwest coast, this site combines calm, nutrient-rich waters with surreal volcanic formations. The dive begins in calm bays and continues into a wall dive, often with chilly thermoclines (as low as 60 F/15 C). Visibility may drop in colder months but marine life flourishes.
Things to See:
This is macro-meets-megafauna territory. Tiny seahorses and frogfish share real estate with mola molas (sunfish), Galapagos fur seals, marine iguanas, and penguins. The rich planktonic soup draws filter feeders and provides stunning photographic opportunities.

About the Galapagos Islands
The Galapagos Islands are located in the Pacific Ocean, roughly 600 miles (1,000 km) west of mainland Ecuador. Formed by volcanic activity, the islands are rugged, raw, and bursting with wildlife. Most are uninhabited and protected as part of the Galapagos National Park and Marine Reserve.
Topside, visitors can expect striking black lava landscapes, cactus forests, and remote beaches teeming with sea lions, iguanas, and nesting seabirds. The atmosphere is eco-conscious and adventurous—luxury options do exist, but even high-end experiences are rooted in nature and conservation.
Getting there and when to go
Visitors to the Galapagos will fly first into either the international airport at Quito or Guayaquil. You’ll usually overnight in one of the two cities (with a convenient airport hotel in Quito) before catching a morning flight on to either Baltra or San Cristobal, depending on where your liveaboard departs from.
The Galapagos Islands are a year-round diving destination, but different seasons bring different conditions. June to November brings colder waters, stronger currents, and the best chance to see whale sharks and large schools of hammerheads.
December to May offers warmer, calmer seas and better visibility, with generally more manta rays and turtles. Land excursions offer the chance to hike volcanoes, spot countless birds, or walk among giant tortoises.
Keep in mind that the Galapagos are highly regulated to protect their fragile ecosystems. Only licensed guides and operators can lead dives, and park fees apply to all visitors.
Liveaboards are the best way to access remote sites like Darwin and Wolf, while day trips are available from the main islands. This is a wild place so be prepared for changing conditions—bring that extra rain jacket or neoprene hood.
Take a moment to look at this.
It really depends on the trip you’re going for. I’d recommend you do the refresher from home and do diving once you’re there.
We would like to do a fresher course one day, and a two tank dive to Darwin the next. Is this offered?
