Santa Cruz is the second largest island in the Galapagos archipelago and its main economic and tourist center. Its capital, Puerto Ayora, is the most populated city of the islands and has a vibrant offer of restaurants, hotels and excursion agencies. Unlike other more arid islands, Santa Cruz has a wide variety of microclimates ranging from dry coastal areas to green, humid highlands. It is the place par excellence to observe the famous giant tortoises in their natural habitat, explore underground lava tunnels and enjoy white coral sand beaches. Its central location makes it the perfect base for daily sailing tours to other uninhabited islands in the national park.
