Your First Look at the Galápagos Islands and What Makes Each Unique

Planning a Galápagos adventure is about more than choosing dates and booking a flight, it’s about understanding the islands and choosing the experiences that will make your trip unforgettable.

Each island in the Galápagos has its own personality, from lava-sculpted coastlines to sleepy fishing towns and wild volcanic craters. The more you know before you go, the more meaningful your experience here will be.

As a local operator based in the Galápagos, we specialize in land-based tours that take you deeper into each island’s unique character. This guide will help you get familiar with the key inhabited and uninhabited islands, and how to decide the best ones for your adventure.

Where Are the Galápagos Islands?

About 1,000 km (600 miles) off the coast of Ecuador, the Galápagos archipelago is made up of 13 main islands, 6 smaller ones, and over 100 islets and rocks. Known as a living laboratory of evolution, this is the only place on Earth where you’ll find creatures like marine iguanas, giant tortoises, and blue-footed boobies thriving in their natural habitat; many of them totally unafraid of humans.

The Four Inhabited Islands: Where You Can Stay

Most travelers stay on two or more of the four inhabited islands. Each offers a unique atmosphere, different wildlife, and activities that shape your experience.

Best Way to Visit

The Galápagos isn’t just about where you go, it’s about how you experience it. The best way to make the most of your trip is by combining land and water adventures in your tour. This means pairing land activities like hiking across lava fields, biking through the highlands, or exploring local villages, with marine activities such as snorkeling, kayaking, or stand-up paddleboarding. This balance allows you to fully appreciate the diversity and beauty of the islands.

If you’re looking for flexibility, cultural immersion, and the chance to explore real island life, land-based tours are a great choice. You’ll stay in comfortable hotels, take day trips to nearby islands, and have plenty of time to relax, take walks on the beach to see sea lions.
