Santa Cruz Island is the beating heart of the Galápagos and is home to the largest town in the archipelago, Puerto Ayora, and a key access point for travelers exploring this unique region. But beyond its small port and shops, the island reveals a surprising range of ecosystems, from black lava shores to lush highlands where giant tortoises roam freely. These ancient reptiles are not just a local symbol, they're part of the reason Charles Darwin's time in the Galápagos changed how the world understands evolution.
One of the island’s most fascinating sites is the Charles Darwin Research Station, where visitors can see conservation efforts up close. This facility played a vital role in bringing the iconic Galápagos tortoise back from the brink of extinction. Lonesome George, the last of his species before his death in 2012, lived here and became a global conservation icon. Today, breeding programs continue to protect several endangered species, and travelers can observe tortoise hatchlings slowly making their way in the world.
The highlands of Santa Cruz feel like another world. A short drive from Puerto Ayora brings visitors to lava tunnels large enough to walk through and wild tortoises grazing in the misty grasslands of El Chato Reserve. It’s not unusual to find one of these massive creatures crossing the road, moving at their own pace. Nearby, Los Gemelos, two massive sinkholes surrounded by a forest of Scalesia trees, offers a peaceful hike and a chance to spot rare birds like the vermilion flycatcher or the Galápagos short-eared owl.
Down on the coast, Tortuga Bay delivers long stretches of white sand and calm turquoise water that’s ideal for kayaking or spotting marine iguanas sprawled across sun-warmed rocks. Another must-visit is Las Grietas, a hidden brackish water canyon perfect for swimming between towering volcanic cliffs. Access is by water taxi and a short walk through a salt flat and lava field, adding a sense of adventure to the experience. Whether hiking, snorkeling, or simply watching pelicans dive for fish, each location feels like a window into another time.
