Suarez Point, Española Island, Galapagos

Española Island

Best for: Birding, waved albatross, dramatic coastal scenery

Oldest island in the Galápagos (est. ~3.5 million years). The only nesting site on Earth — thousands of pairs breed here April–December. Punta Suárez is rated by many naturalists as the single best visitor site in the archipelago.

Bird's eye view of Fernandina Island

Fernandina Island

Best for: Pristine wilderness, flightless cormorants , active volcano

Youngest and most volcanically active island. La Cumbre Volcano last erupted in 2024. Zero invasive species have ever established here. Espinoza Point hosts the largest marine iguana colony in the Galápagos and the world’s entire flightless cormorant population. Western itineraries only.

Floreana Island, Galapagos Islands, Ecuador

Floreana Island

Best for: History, flamingos, small-group intimacy

The most dramatic human history in the archipelago — the 1930s Floreana Affair (European settlers, a self-styled baroness, suspicious disappearances) is still unsolved.

Frequently Asked Questions

How many islands can you visit in the Galápagos?

Visitors can access approximately 50 visitor sites across 20+ designated islands and islets. A typical 8-day cruise visits 8–10 sites across 5–7 islands. Some islands (Darwin, Wolf) are accessible only by liveaboard dive cruise. Fernandina, Española, and Genovesa require western or northern itineraries not available on 4–5 day trips.

Which Galápagos island is the best to visit?

There is no single best island — each serves a different purpose. Santa Cruz is the best base for land-based travelers. Española has very high endemic species density per square kilometer by most naturalist assessments. Fernandina offers the most pristine environment. The right answer depends on whether you prioritize accessibility, wildlife density, photography, diving, or history.

Do you have to visit the islands by cruise?

No. The four inhabited islands (Santa Cruz, San Cristóbal, Isabela, Floreana) are accessible via inter-island ferries ($30–35 per route, ~2–2.5 hours) or short-hop flights. The uninhabited islands are accessible only via National Park-authorized day tours or overnight cruises — independent access is prohibited by park regulation.
