Today we reached the mainland, one of the oldest islands in the archipelago. We saw endemic species unique to this island, including the San Cristobal mockingbird and the San Cristobal lava lizard. We also saw for the first time red-footed boobies, most of them being occupied with nest building. In addition, we observed a couple of blue-footed boobies in full courtship. Female marine iguanas were also digging their nest to lay eggs.

After lunch, we disembarked to Cerro Brujo for a wonderful walk around a white sandy beach. At 5:00 p.m. we all came back to National Geographic Islander to sail to Puerto Baquerizo Moreno. This is the capital of the Galapagos, where along the way we passed Kicker Rock, a well-known tuff formation, and an ideal one to conclude this memorable expedition.
