Charles Darwin formed the theory of evolution while studying the Galapagos Islands.

Out of his 5-year voyage on the HMS Beagle, Charles Darwin only spent 5 weeks at the Galapagos Islands. However, he left the islands with the discovery of a lifetime. While observing the island’s flora and fauna, Darwin noticed the difference in local finches’ beaks depending on the environment and food source of each island. Later on, the English naturalist used this observation as a basis for the theory of evolution presented in ‘On the Origin of the Species.’

Isla Santa Cruz houses the largest human population in the Galapagos Islands.

A majority of the Galapagos Islands population lives in Puerto Ayora. This town which also houses the Charles Darwin Research Station and the Galapagos National Park Service is in the same place.

Galapagos Islands is home to 3 species of boobies.

No, it’s probably not the boobies you’re thinking about: The red-footed boobies are the smallest species, while the Nazca Boobies are the largest. Nazca boobies have gleaming white plumage and black-tipped feathers. Lastly, the blue-footed boobies parade their striking feet to attract mates. How’s that for cool Galapagos Islands facts?

Another name for the Galapagos Islands is the ‘Enchanted Islands.’

It is in reference to how the strong waves and swift currents around the islands made navigation difficult.

As an archipelago, the Galapagos Islands have 13 main volcanic islands.

Other than that, it also has 107 rock formations and islets, and 6 smaller islands.

The oldest island in the Galapagos Islands formed 5-10 million years ago.

According to studies, the first island in the Galapagos formed due to tectonic activity millions of years ago. To this day, new islands are still being formed tin the Galapagos through volcanic eruptions.

Galapagos Islands did not appear on any maps until around 1570.

If you lived before the late 1500s, you probably wouldn’t see the Galapagos Islands on your geography textbooks. Abraham Ortelius and Mercator first drew the islands in 1570, naming it Insulae de Los Galopegos which translates to ‘Islands of the Tortoises.’

Volcanic eruptions formed the Galapagos Islands.

The archipelago of the Galapagos was the product of over 1,000 years of volcanic activity. Continuous volcanic eruptions caused the buildup of igneous rock layers on the ocean floor, which eventually formed the islands.

Tomás de Berlanga made the first recorded visit to the Galapagos Islands.

Tomás de Berlanga was a Spanish nobleman and a bishop from Panama. While sailing from Panama to Peru in 1535, his ship veered off course – which accidentally led him to the Galapagos Islands.

Galapagos Islands is home to the only penguin species found in the northern hemisphere.

The Galapagos penguins are the only ones separated from their siblings in the Arctic. The Galapagos penguins reside mainly on Isla Fernandina and Isla Isabela. The penguins survived a tropical Ecuadorian habitat due to the nutrient-rich water of the Humboldt Current.

The Galapagos Islands' Isla Baltra served as a US Air Force base in WWII.

Aside from protecting the Panama Canal, crews were stationed at the Isla Baltra or ‘South Seymour’ to monitor the Pacific for enemy submarines.

Today, Isla Baltra continues to serve as an official military base for Ecuador.

Long after WWII, the Ecuadorian government now makes use of the war facilities in Isla Beltra.

Isla Bartolomé got its name from British Navy’s  Lt. David Bartholomew.

Isla Bartolomé is a small island east of Isla Santiago. Although desolate, Isla Bartolomé is among the most photographed and most visited islands in the archipelago. Bartholomew Island takes after the name of a lieutenant aboard the HMS Beagle, Lt. David Bartholomew.

The Isla Bartolomé is an extinct volcano.

Various colored volcanic formations and a tuff cone called Pinnacle Rock are among the distinct features of the island. When lava touched the sea, the result was the large, black, and partially eroded cone that is the Pinnacle Rock.

A wide variety of birds take shelter in Isla Bartolomé.

97% of the Galapagos Islands are national parks.

Galapagos National Park has been protecting over 3,000 sq mi. of islands and islets. Likewise, the Galapagos Marine Reserve protects the 50,000 sq mi. of ocean surrounding the islands which are also listed as a UNESCO Biosphere Reserve.

The Galapagos Islands experience 2 different seasons.

The hot seasons give warmer and humid weather from December-May. On the other hand, the dry season is slightly cooler and lasts from June-November. These seasons make the island either lush green or slightly barren and arid.

The Galapagos Islands get more rainfall during the hot season.

With an average temperature around 79°F or 26°C, warmer ocean temperatures and calmer seas come alongside it. The dry season over the Galapagos Islands brings a breeze ideal for increased marine activity. How’s that for Galapagos Islands facts?

UNESCO lists the ocean around the Galapagos Islands as a Biosphere Reserve.
