Best Islands to Visit in Galapagos
A complete guide to Ecuador’s most extraordinary archipelago — wildlife, beaches, history, and the islands that will leave you speechless.
Why Visit the Galapagos Islands?
Few places on Earth can match the Galapagos Islands for sheer wildlife spectacle and natural wonder. This remote archipelago in the Pacific Ocean is home to animals found nowhere else on the planet — and they’re completely unafraid of humans.
Is Galápagos worth visiting? Without question — yes. Whether it’s your first time traveling to Ecuador or you’re a seasoned adventurer, the Galápagos delivers an experience unlike any other destination in the world. Snorkeling alongside sea lions, watching giant tortoises roam freely, and walking on lava fields that feel like another planet — it’s all here, waiting for you.
But with 19 major islands and dozens of smaller islets spread across nearly 60,000 square kilometers of ocean, planning your visit can feel overwhelming. This guide breaks down the best islands to visit in Galápagos, what makes each one unique, and everything you need to know to make the most of your trip.
Where is Galapagos Islands Located?
The Galapagos Islands are located about 1,000 km (620 miles) west of Ecuador’s mainland coast, straddling the equator in the Pacific Ocean. What country are the Galápagos Islands in? They officially belong to Ecuador and are administered as a special province. The closest continent is South America.
This geographic position also explains the islands’ volcanic origin: they sit atop a geological “hot spot” that continues to push new islands upward from the ocean floor.
How Many Islands Are in the Galapagos?
The Galapagos archipelago includes 19 major islands, 6 smaller islands, and over 40 islets and rocks. Of these, only 4 islands are permanently inhabited: Santa Cruz, San Cristóbal, Isabela, and Floreana. The total human population is around 30,000 people — small by any measure — which helps preserve the natural environment that makes the islands so special. Roughly 97% of the Galapagos’ total land area is protected as a national park, with human settlements confined to the remaining 3%. This strict conservation model is part of why the wildlife here is so abundant and fearless.
The Best Galapagos Islands to Visit
Not all islands are equal — some are better for snorkeling, others for wildlife, and others for history. The Galapagos wildlife islands are collectively unmatched anywhere in the world, but each one offers a different flavor of that experience. Here are the four islands that should be at the top of your Galapagos travel itinerary.
Santa Cruz Island: Things to Do
Santa Cruz is the most visited island in Galápagos — and for good reason. It’s home to Puerto Ayora, the largest town in the archipelago, as well as the Charles Darwin Research Station, where you can meet giant tortoises up close and learn about ongoing conservation work.
When it comes to things to do in Santa Cruz Galápagos, the list is remarkably long. The island’s interior highlands are lush and green, a stark contrast to the volcanic coastline. Here, wild giant tortoises roam freely across private farmlands — a truly unforgettable sight.
- Charles Darwin Research Station
- Tortoise Reserve in the highlands
- Tortuga Bay — one of the most beautiful beaches in the Galapagos
- Los Túneles lava tubes (excellent snorkeling)
Isabela Island Things to Do in the Galapagos' Largest Island
Isabela is the largest island in the Galápagos, formed by the merging of six shield volcanoes — five of which are still active. Its dramatic landscape includes vast lava fields, calderas, and some of the archipelago’s most pristine wildlife habitats.
Isabela Island, Galapagos, things to do range from volcano hikes to penguin watching and world-class snorkeling. It’s the best island to visit if you’re looking for a more off-the-beaten-path experience — quieter than Santa Cruz but absolutely packed with wildlife encounters.
- Unique marine iguanas — the world's only sea-going lizard
- Sierra Negra volcano hike (one of the largest calderas on Earth)
- Penguin colonies at Tintoreras
- Flamingo lagoon near Puerto Villamil
San Cristóbal Island
San Cristóbal holds a special place in Galápagos history: it was the first island colonized by humans in the archipelago, and it’s also believed to be one of the first places Charles Darwin set foot during his 1835 voyage. Today, its capital, Puerto Baquerizo Moreno, serves as the official capital of the Galápagos province.
The island has a distinct cultural character compared to Santa Cruz, and its laid-back atmosphere makes it a great destination for travelers who want to blend wildlife encounters with local life.
- Frigate bird hill (Cerro Tijeretas) — ideal for snorkeling with sea lions
- Interpretation Center for Galápagos history
- Playa Mann and Lobería beach (sea lion colonies)
- Kicker Rock (León Dormido) — a world-class diving site
Floreana Island
Floreana is the most historically intriguing island in the Galápagos. It was the first island in the archipelago to be permanently inhabited. In the 1930s, it was the setting of one of the most mysterious and unsolved crimes in the history of the Pacific — the disappearance and death of several German settlers who had come to live as utopian pioneers.
Today, Floreana is home to fewer than 200 permanent residents and attracts visitors looking for history, pink flamingos, and pristine snorkeling.
- Post Office Bay — a 200-year-old tradition of leaving and delivering letters
- Punta Cormorant — flamingo lagoon and green-sand beach
- Devil's Crown — one of the top snorkeling sites in the archipelago
- Pink flamingos in Floreana's wetlands
How to Get to Galapagos from Ecuador
Flights to the Galápagos depart from Quito (UIO) and Guayaquil (GYE) in mainland Ecuador, with landing options at San Cristóbal Airport or Baltra Airport (near Santa Cruz). Most visitors fly through Guayaquil for the shortest connection. Flight time is approximately 2–3 hours.

Fun Facts About the Galapagos Islands
The Galapagos Islands’ unique animals and extraordinary natural history make them one of the most fascinating places on Earth. Here are some of the most surprising facts you probably didn’t know.
- The Name Comes from the Tortoises
The word “Galapagos” comes from an old Spanish word for saddle — a reference to the saddle-shaped shells of the giant tortoises the first explorers encountered - Still Being Formed
The Galapagos Islands were formed by volcanic activity above a “hot spot” on the Pacific Plate. Several volcanoes are still active today — Isabela’s Wolf Volcano last erupted in 2022. Darwin’s Inspiration
Charles Darwin visited the Galapagos in 1835 during his voyage on the HMS Beagle. His observations of finches and tortoises across different islands helped inspire his theory of evolution by natural selection.- The Only Tropical Penguins on Earth
The Galapagos penguin is the only penguin species found north of the equator, and one of the rarest in the world, with fewer than 2,000 individuals remaining. - UNESCO and World Heritage Status
The Galapagos Islands were one of the first sites inscribed on the UNESCO World Heritage List in 1978, recognized for their exceptional universal value to science and nature. - The World’s Oldest Postal Service
Floreana’s Post Office Bay has been in operation since the late 1700s, when whalers would leave letters for ships heading home. Visitors still honor the tradition today.
Conservation Protecting the Galapagos: Why It Matters
The Galapagos Islands are one of the last places on Earth where wildlife evolved without fear of predators — including humans. Keeping it that way requires constant effort.
The Galapagos National Park was established in 1959 and today protects 97% of the archipelago’s land area. The Charles Darwin Foundation, based in Santa Cruz, has been conducting scientific research and supporting conservation efforts on the islands since 1961.
Invasive species are one of the greatest threats to the Galapagos ecosystem. Introduced animals like goats, rats, and cats have caused massive damage to native species. Thanks to large-scale eradication programs, several islands have been successfully cleared of invasive species, allowing native populations to recover.
Tourism is carefully managed: all visitors must enter with a licensed naturalist guide, stay on designated trails, and follow strict rules about interacting with wildlife. Sustainable tourism in the Galapagos is not optional — it’s built into the national park’s legal framework. These measures help ensure that the millions of visitors who come each year have a minimal impact on the fragile ecosystem.
Galapagos National Park Rules for Visitors
- Always travel with a licensed naturalist guide
- Stay on marked trails — never step off them
- Keep a distance of at least 2 meters from all wildlife
- Never feed the animals, even if they approach you
- Don't bring fresh fruits or vegetables from the mainland
- Take all your trash back with you — leave nothing behind
- Use reef-safe sunscreen to protect the marine ecosystem
- Support locally owned tour operators and businesses
