Key Takeaways
- The Galapagos Islands span over 17,000 square miles, featuring 13 main islands and many smaller islets. Isabela is the largest, stretching 120 kilometers with six volcanoes. Baltra, the main air hub, handles over 2,000 flights each year.
- Unique, endemic wildlife thrives here. Species like the giant tortoise, marine iguana, flightless cormorant, blue-footed booby, and endangered Floreana Mockingbird evolved in isolation and live nowhere else on Earth.
- Conservation projects have removed invasive goats from islands like Pinzon (by 2012) and Floreana (by 2007). Initiatives such as Project Isabela have helped restore native ecosystems once threatened by non-native species.
- Charles Darwin visited in 1835 aboard the HMS Beagle. His study of finches’ beaks and mockingbird variations here later inspired his theory of evolution by natural selection.
- Some zones, including Plaza Norte and Marchena, are strictly off-limits to visitors to protect sensitive habitats. In 1978, UNESCO recognized the Galapagos as a World Heritage Site for its unmatched biodiversity.

Pinta covers 60 square kilometers and rises to 777 meters, making it the northernmost of the major Galapagos Islands. Once known as Abingdon Island, its name now honors one of Columbus’s ships.
This island holds a poignant place in Galapagos history as the home of Lonesome George, the last known Pinta tortoise, who passed away in June 2012.
In 1959, invasive goats devastated native plants, but by 1999, conservationists had successfully removed them. Today, Project Pinta leads restoration efforts to revive xeric scrub habitats and support native species like the Galapagos hawk (Buteo galapagoensis) and woodpecker finch (Camarhynchus pallidus).
At Punta Neros, visitors may spot unique marine life such as the Red-lipped Batfish or snorkel in rich waters near this rift zone hotspot, shaped seasonally by El Niño currents.
With no permanent human presence, Pinta remains wild and untouched.
Nestled near the center of the Galapagos, Pinzon Island spans just 18 square kilometers, its slopes cloaked in lush Scalesia forests. Named after the Pinzon brothers, captains on Columbus’s historic voyage, this uninhabited island remains off most visitor routes.
Access is highly restricted to protect its fragile ecosystems and rare species.
Conservationists have fought to save the endemic Pinzon giant tortoise, once nearly lost to invasive rats that preyed on every hatchling. A successful rat eradication program turned the tide, allowing new generations to survive.
Today, visitors may glimpse tortoises moving through the undergrowth, lava lizards skittering over rocks, and Galapagos hawks soaring overhead, all thriving under careful management in this living laboratory of evolution.
Also known as South Seymour, Baltra spans 21 square kilometers and rises 100 meters above sea level. Its dry landscape is scattered with salt bush and towering prickly pear cactus.
During World War II, the U.S. built an airbase here with over 200 buildings to monitor Pacific waters. The first Galapagos airport opened in the 1930s, carved into this rugged volcanic terrain.
When I landed here for my own Galapagos journey, the thrill was immediate—land iguanas basked under the equator’s intense sun.
By the 1950s, land iguanas had vanished from Baltra. But in the early 1990s, conservation teams successfully reintroduced them using individuals from North Seymour Island.
Today, Baltra plays a key role in ecotourism, with one of the two main airports linking mainland Ecuador to the archipelago. Strict protection rules help safeguard the local wildlife as thousands of visitors pass through each year.
Seasonal rains briefly turn the landscape green before the sun dries it once again.
Floreana spans 67 square miles and rises to 2,100 feet, home to just about 140 residents, making it one of the smallest communities in the Galapagos Province.
In 1793, early whalers set up the first post office at Post Office Bay, where travelers still leave postcards, hoping for a hand-delivered surprise.
Floreana’s history carries a mysterious edge, with tales of disappearances in the 1930s still echoing through its rugged hills.
Visitors flock to Cormorant Point to spot flamingos and rays, and dive into the waters of Devil’s Crown, a top snorkeling site filled with vibrant marine life.
Conservation teams are working to save the endangered Floreana Mockingbird, battling invasive predators that pose a threat during the dry season.
After discovering Floreana’s rich history, many travelers head to Espanola, the southernmost island in the Galapagos. Formed 3.5 million years ago, its age and isolation gave rise to a unique ecosystem.
Here, the red marine iguana patrols the rocky shore, and Punta Suarez bursts with seabird activity. Visitors may spot blue-footed boobies, Nazca boobies, and witness the waved albatross performing its remarkable courtship dance—the only nesting site for this species on Earth.
At Gardner Bay, a stunning coralline sand beach invites you to relax among sea lions basking in the sun. With no human settlements, Espanola offers a rare glimpse of untouched Galapagos wildlife.
Giant tortoises were reintroduced here through successful conservation programs led by local scientists and supported by organizations like the World Wildlife Fund. The legacy of figures like José de Villamil continues to inspire travelers seeking meaningful, nature-driven adventures aboard the ships of Darwin Adventures.
Reachable by a 10 to 12-hour boat trip from Santa Cruz, Espanola rewards those who venture far with unforgettable wildlife moments—because here, nature always takes center stage.
Rising steeply from the deep blue waters of the Galapagos, Santa Fe covers just 24 square kilometers, with its highest point reaching 259 meters above sea level. Its lava formations and ancient rocks date back 3.9 million years, making it one of the oldest volcanoes in the archipelago.
There are no human settlements here—only wildlife thrives among towering giant Opuntia cactus forests.
Prickly pear trees stretch overhead as sea lions lounge in the shade and pelicans glide above turquoise bays.
During my hike on both trails with the Galapagos Santa Cruz Ship, I spotted incredible endemic wildlife, including the bright yellow Santa Fe land iguana darting across sun-warmed rocks and the elusive Santa Fe rice rat rustling among the roots.
Invasive rats once posed a major threat to these rare species. But in 2015, biologists launched a bold restoration project, introducing Espanola giant tortoises to help rebalance the ecosystem.
Today, Santa Fe stands as a living laboratory of renewal, not far from Volcan Wolf and Floreana Island, where nature is thriving once more.
Small Islands
Beyond the main islands, the smaller islets of the Galapagos reveal the archipelago’s most untouched beauty. Daphne Major and Minor rise dramatically from the sea, leading to Bartolomé, where wooden stairs climb to breathtaking views of Pinnacle Rock. Each island has its own color and character—Rábida glows with red iron sands, while Plaza Sur contrasts vivid red plants against deep blue waters.
