Tours in Santa Cruz Island, Galapagos – Giant Tortoises, Marine Life & Pristine Beaches

Santa Cruz Island tours offer the most complete Galapagos experience available. As the most visited island in the archipelago and home to Puerto Ayora — the largest town in the Galapagos — Santa Cruz is the perfect base for exploring the natural wonders that make these islands a UNESCO World Heritage Site. From the highlands where giant tortoises roam freely to the white-sand beaches teeming with marine iguanas and sea lions, Santa Cruz has something extraordinary at every turn.

Why Choose Santa Cruz for Your Galapagos Adventure?

Santa Cruz is where the famous Charles Darwin Research Station is located — the center of Galapagos conservation since 1964. Visiting here gives you direct insight into the breeding programs that saved the Galapagos giant tortoise from extinction. The island's unique geography spans coastal mangroves, dry lowlands, and misty highland forests, creating a mosaic of habitats that supports an astonishing variety of wildlife.

At Tortuga Bay, just a 2.5 km walk from Puerto Ayora, you'll find one of the most stunning beaches in the Pacific — a 1.5 km stretch of white sand where marine iguanas sun themselves beside basking sharks. The calm waters of the inner lagoon are ideal for kayaking, swimming, and spotting marine turtles and white-tip sharks. Las Grietas, a dramatic lava gorge filled with crystal-clear saltwater, is perfect for snorkeling and cliff-jumping adventures.
