Scuba Diving in Ecuador

Scuba diving in Ecuador means two very different oceans in one small country. Nearly 1,000 km (620 mi) offshore, the Galapagos serves up the biggest big-animal diving on the planet, with schooling hammerheads, whale sharks, and marine iguanas grazing underwater. Back on the Pacific coast, Isla de la Plata and Ayangue offer warm-water day diving with oceanic mantas at a fraction of the price. Beyond the diving, Ecuador packs the colonial old town of Quito, snow-capped volcanoes, and the Amazon rainforest into a country you can cross in a day.

Why dive in Ecuador?

• The best big-animal diving on Earth — schooling scalloped hammerheads, whale sharks, sea lions, and penguins at the far-northern Galapagos sites of Wolf and Darwin.
• Two oceans, one country — cold-current island diving 1,000 km (620 mi) offshore, plus warm-water day boats on the mainland Pacific coast.
• The world's largest giant manta aggregation — oceanic mantas gather off Isla de la Plata and Bajo Cope from July to September.
• Creatures found nowhere else — the only seagoing lizard on the planet and the only penguin north of the equator, both dived from the same boat.
• Diving at every budget — mainland two-tank days run $170 to $190, while the Galapagos scales all the way up to bucket-list liveaboards.
• Conservation at scale — the 138,000 km² (53,000 sq mi) Galapagos Marine Reserve, joined in 2022 by the 60,000 km² (23,000 sq mi) Hermandad Reserve.

Where to dive in Ecuador

Ecuador's diving splits between the world-famous Galapagos and a quieter stretch of mainland coast, and the right pick comes down to your budget and how much current you want.

Galapagos

Galapagos

If you want the heavyweights, schooling scalloped hammerheads, whale sharks the size of a bus, penguins, and sea lions that buzz you on your safety stop, this is the single best big-animal dive destination on Earth. Liveaboards reach the far-northern sites at Wolf and Darwin, while land-based day boats out of Santa Cruz and San Cristobal cover the central islands for a fraction of the cost.

Isla de la Plata

Isla de la Plata

Isla de la Plata is the mainland's answer to the archipelago (locals call it the poor man's Galapagos), where day boats from Puerto Lopez put you in the water with oceanic manta rays from July to September.

Ayangue

Ayangue

Learning to dive, or diving on a backpacker budget? Ayangue is a small fishing bay wrapped around the El Pelado Marine Reserve, with a dozen easy reef sites and the giant mantas of Bajo Cope an hour offshore.

Best time to dive

Diving conditions in Ecuador follow two seasons. The warm season from December to May brings calmer seas, better visibility, and water of 24–28 °C (75–82 °F) in the Galapagos. The cool garua season from June to November churns up nutrient-rich upwellings, drops temperatures to 16–24 °C (60–75 °F), and pulls in the whale sharks and the biggest hammerhead schools.

The mainland coast peaks from June to September, when the oceanic mantas and humpback whales arrive in 20–25 °C (68–77 °F) water. So if big animals are the goal, the second half of the year is Ecuador's prime time across both coasts. If you would rather trade some of the action for warmer, clearer water and gentler surface conditions, aim for the first half of the year instead.

Diving conditions

• Water temperature: 24–28 °C (75–82 °F) in the Galapagos warm season, dropping to 16–24 °C (60–75 °F) in the cool garua season; 20–25 °C (68–77 °F) on the mainland coast
• Visibility: 10–25 m (33–82 ft) in the islands, at its best during the warm months from December to May
• Currents: strong in the Galapagos, with surge, sharp thermoclines, and negative entries at the northern sites; far gentler on the mainland
• Seasons: December to May for calm seas and clear water, June to November for whale sharks, the biggest hammerhead schools, mantas, and humpbacks

Marine life highlights

Marine life in Ecuador is shaped by a collision of currents. The cold Humboldt and Cromwell currents slam into warm equatorial water at the Galapagos, feeding one of the richest and strangest marine ecosystems anywhere, where penguins share reefs with tropical fish. The same nutrient-rich Pacific bathes the mainland coast, pulling in oceanic mantas and migrating humpbacks every year. Nothing in Ecuador is guaranteed except variety: the same trip can hand you a penguin, a wall of hammerheads, and an iguana chewing algae at 5 m (16 ft).

• Scalloped hammerhead (Sphyrna lewini) — year-round in the Galapagos, with the biggest schools from June to November around Wolf and Darwin.
• Whale shark (Rhincodon typus) — July to October, especially around Darwin, where most passing individuals are huge, apparently pregnant females.
• Oceanic manta ray (Mobula birostris) — July to September around Isla de la Plata and Bajo Cope, the largest known seasonal aggregation of giant mantas in the world.
• Marine iguana (Amblyrhynchus cristatus) — the world's only seagoing lizard, best watched feeding underwater in the warm season around Fernandina and the central islands.
• Galapagos penguin (Spheniscus mendiculus) — the only penguin north of the equator, darting past divers around Isabela and Fernandina.
• Mola mola (ocean sunfish) — a cool-season visitor, especially around Punta Vicente Roca on western Isabela.
• Humpback whale (Megaptera novaeangliae) — June to September off Puerto Lopez, often heard singing underwater and regularly spotted breaching beside the boat.

Conservation

Ecuador protects its ocean at a scale few countries can match. The Galapagos Marine Reserve covers 138,000 km² (53,000 sq mi), and in 2022 the country added the 60,000 km² (23,000 sq mi) Hermandad Reserve, half of it a full no-take zone guarding the 700 km (435 mi) Swimway that migrating sharks and turtles follow to Cocos Island. Together with Costa Rica, Panama, and Colombia, Ecuador anchors the CMAR corridor, over 500,000 km² (193,000 sq mi) of connected protection, and nearly 19% of its waters are now safeguarded. The threats are real, from illegal fishing fleets to warming El Nino water, so the park enforces strict rules: no touching, mandatory guides, and your $200 entry fee funds patrols and invasive species control.

How you can help: Support the Charles Darwin Foundation and the Galapagos Conservation Trust, both of which welcome diver contributions, and book with operators that run citizen-science shark counts you can join. Read more about Divearoo's Conservation First policies.

Ecuador culture — other reasons to go

Almost every dive trip to Ecuador connects through Quito or Guayaquil, and it would be a waste to treat them as layovers. Quito's old town is one of the best-preserved colonial centers in South America and was among the first UNESCO World Heritage Sites ever named, with gilded churches like La Compania and a cable car that lifts you to 4,000 m (13,000 ft) above the city. Two hours north, the Otavalo market is the largest indigenous market on the continent. To the south, the Avenue of the Volcanoes runs past Cotopaxi's near-perfect cone, and a short flight east drops you into Amazon lodges with pink river dolphins and canopy towers. Even divers staying on the coast get culture on their surface days, from the Agua Blanca community inside Machalilla National Park to fresh ceviche shacks on the malecon in Puerto Lopez.

• Quito old town — spend your first or last night wandering the plazas and gilded churches of a UNESCO World Heritage city at 2,850 m (9,350 ft).
• Otavalo market — haggle for alpaca textiles at South America's largest indigenous market, an easy day trip from Quito before your flight to the islands.
• Cotopaxi National Park — hike or mountain bike beneath a 5,897 m (19,347 ft) active volcano on your way down the Avenue of the Volcanoes.
• Amazon lodge stay — add three days in the Ecuadorian Amazon, one of the cheapest and most accessible corners of the entire rainforest.
• Los Frailes beach and Agua Blanca — a surface-interval combo inside Machalilla National Park, minutes from the Puerto Lopez dive docks.
• Cacao farm tour — taste the fine-aroma chocolate Ecuador is famous for at farms near Guayaquil and the coast.

Practical information

Dive prices

Ecuador runs from backpacker cheap to bucket-list expensive. On the mainland, a full-day two-tank trip to Isla de la Plata costs $170 to $190 including lunch and gear, and local reef dives at Ayangue cost less. In the Galapagos, land-based two-tank day trips from Santa Cruz or San Cristobal typically run $230 to $290, while liveaboards range from about $650 to $1,050 per night, putting a 7-night Wolf and Darwin itinerary anywhere from $4,700 to over $7,300 on current rates. Country-wide, call it $$$ (mainland $$, Galapagos $$$$).

Visa information

Citizens of the US, UK, EU, Canada, and Australia don't need a visa for Ecuador and get 90 days on arrival free of charge, extendable once to 180 days from inside the country. Your passport needs six months of validity, and officials may ask for proof of onward travel.

Park and entry fees

The Galapagos adds its own paperwork on top of the national entry rules. You'll need a $20 Transit Control Card, purchased online at least a week before your flight from Quito or Guayaquil, plus the Galapagos National Park entry fee of $200 for foreign adults ($100 for children under 12), which doubled from $100 in August 2024 and is payable in cash on arrival at Baltra or San Cristobal. Budget $220 per person in fees before your first dive in the islands. The mainland coast has no equivalent charge.
