The highest rates of endemic species are found in the eastern and southern islands. This is due to the fact that they are the first islands on the path of the prevailing winds and currents which flow from the southeast. This means that creatures have been established here for longer, giving them time to evolve into new forms. Amongst the endemic species unique to Española we can find the mockingbirds, lava lizards and the Española ground finch. The island is also home to the only tropical albatross in the world: the waved albatross. The white coralline beaches and bays of the island make the perfect habitat for one of the most charismatic species of the islands, the Galapagos sea lion.

Isabela Island
Tuesday on Isabela Island began with a wet landing at Urbina Bay where guests ventured on a nature walk along gentle terrain shaped by dramatic geological uplift. The trail revealed fascinating coastal formations and offered close encounters with endemic wildlife, including our first encounter with Galapagos giant tortoises, land iguanas, penguins, and flightless cormorants. After the walk, guests had the option to swim or snorkel from the beach where the calm and clear waters provided a refreshing break before everyone returned to National Geographic Gemini. In the afternoon, we continued north toward Punta Vicente Roca. Guests gathered at the bow with the expedition leader to take in the striking volcanic landscape and learn more about the island’s natural history. The day’s exploration continued with a Zodiac ride along the coast of Ecuador Volcano, offering a closer look at the rugged shoreline and opportunities to spot wildlife, such as sea turtles, penguins, and Galapagos fur seals. As the sun dipped below the horizon, the ship crossed the equator, marking the moment with a pod of dolphins during sunset — a memorable finale to a day filled with discovery, connection with nature, and the wild beauty of the Galápagos.
