You don’t need a tank to encounter something extraordinary here. But for certified divers, a second, deeper, world is waiting below.
Snorkeling in the Galapagos surpasses the underwater encounters most travelers find anywhere else in the world, and it is included as a daily activity on every Ecoventura expedition cruise aboard Origin, Theory, and Evolve. No certification required. Guests swim alongside sea lions, marine iguanas, Galapagos penguins, and white-tip reef sharks as a core part of their itinerary, with daily guided snorkeling sessions, and additional opportunities on select expedition days, led by expert naturalist guides who know exactly where the wildlife is most active.
For certified divers with prior open-water experience, a dedicated liveaboard with Galapagos Sky, Ecoventura’s sister dive company, reveals a more advanced side of the archipelago: powerful currents, pelagic encounters, and remote northern islands accessible only through liveaboard expeditions.
This isn’t a choice between two activities. It’s an invitation to think about layering both into one extraordinary 2027 expedition.
Two very different underwater worlds
Before going deeper on each experience, here is what each one structurally offers — and what it asks of you.
Snorkeling on an expedition cruise
Aboard Origin, Theory & Evolve
A daily activity included in every Ecoventura expedition cruise. Explore shallow reefs, protected bays, and rocky coastal sites alongside expert naturalist guides. No certification or prior snorkeling experience is required for shallow water snorkeling. Before each session, your guides provide a full safety briefing, accompany guests in the water, while our zodiac drivers remain nearby for added support. For deep water snorkeling, guests must be competent swimmers without touching bottom, and have some prior experience snorkeling. Flotation vests are always available for those who want extra confidence in the water.
- No certification or prior experience required
- Daily guided snorkeling sessions
- Naturalist guides in the water with guests
- Zodiac support throughout each activity
- Possible wildlife encounters: Sea lions, Galapagos penguin, marine iguana, reef sharks, green sea turtles, reef fish, rays, and more
- Included in cruise fare
Scuba liveaboard with Galapagos Sky
A dedicated dive expedition
- Open Water certification minimum
- Nitrox certification and current-diving experience recommende
- Minimum 50–100 logged dives preferred
- 3–4 dives per day at elite dive sites
- Possible wildlife encounters: hammerhead sharks, manta rays, whale sharks (seasonal), marine iguana, and more
- Separate booking via Galapagos Sky
Explore the Galapagos on 7- and 10-night liveaboard expeditions, with up to 4 dives per day across the archipelago’s most legendary sites — including Wolf Island and Darwin Island, the remote northern islands accessible only by liveaboard.
What snorkeling on an Ecoventura cruise actually delivers
Snorkeling in the Galapagos is not the same as snorkeling in the Caribbean or Southeast Asia. The conditions, the biodiversity, and the sheer density of animal life here are categorically different — a product of the nutrient-rich currents that converge around the archipelago and the protection afforded by one of the world’s most strictly managed national parks.
On a typical Ecoventura expedition, snorkeling sessions happen at least once, daily. Each session is led by a certified naturalist guide who plans each landing around peak wildlife activity: which bay holds the Galapagos penguins in the morning, which channels the reef sharks favor at slack tide, where the sea lions are patrolling their reef.
Wildlife you can realistically expect to encounter while snorkeling
- Sea lions: Almost daily · playful and curious
- Galapagos penguins: Site-dependent · Isabela, Fernandina, Chinese Hat & Bartolomé
- Marine iguanas: Fernandina & Isabela · feeding underwater
- Flightless cormorants: Rare and site-dependent · Isabela & Fernandina
- White-tip reef sharks: Common · resting in shallow channels
- Green sea turtles: Frequently seen · across multiple islands
- Golden & spotted rays: Sandy bottoms and tidal channels
The Galapagos’ famous fearlessness extends underwater. Protected for generations, many species here continue their natural behaviors in the presence of respectful observers, creating encounters that feel remarkably close and deeply personal. Sea lions may glide effortlessly around snorkelers, sea turtles often surface nearby before disappearing into the blue, and white-tip reef sharks can sometimes be seen resting along sandy channels and rocky reefs.
Good to know:
Ecoventura equips all snorkelers with wetsuits, masks, and fins, and provides flotation aids for those who want them. Children and inexperienced swimmers can participate with appropriate supervision. Water temperatures range from 18°C to 26°C (64°F to 79°F) depending on season and site.
If you require prescription snorkel masks, we recommend bringing your own, as these are not available on board.
What only scuba diving can reach
If the surface is extraordinary, what happens when you descend? The Galapagos reveals a second, more dramatic version of itself — defined by deep-water pelagics, powerful ocean currents, and a concentration of marine biomass that brings marine biologists back year after year. This is the world Galapagos Sky was built to access.
Typical depth range by experience type
- Snorkeling: 0–5 m
- Scuba · regular sites: 10–18 m
- Wolf & Darwin Islands: 20–32 m
Wolf and Darwin Islands: the reason certified divers make the trip
Located 190 km north of the main archipelago, Wolf and Darwin are among the most biodiverse dive sites on the planet — accessible only by liveaboard. No day trips. No ferry. No exceptions. Galapagos Sky makes dedicated passages to these islands, and the dives there are the reason serious underwater photographers, marine biologists, and bucket-list divers specifically build their expeditions around them.
At Wolf and Darwin, divers encounter:
- Whale sharks — the world’s largest fish, frequently sighted at depth from June through November
- Scalloped hammerhead sharks — schooling in formations of hundreds along thermoclines
- Giant manta rays — circling cleaning stations in open water
- Silky sharks and Galapagos sharks — in numbers that make these among the most shark-dense dives in the world
- Dolphins, marlins, and tuna — in the open water column between dives
Currents at these sites can be strong — this is advanced diving territory, best suited to certified divers with 50–100 logged dives, prior open-water experience, and confidence diving in currents. Nitrox certification is strongly recommended. The Galapagos Sky dive team provides thorough briefings, full equipment, and nitrox options for extended bottom time.
