Upon arriving on Bartolome Island, you will discover a fascinating moonscape formed by various volcanic formations — including lava bombs, spatter, cinder cones — as we hike to the island’s summit for striking views of the surrounding islands, Sullivan Bay and the towering Pinnacle Rock. As the beaches at the foot of the Pinnacle Rock boast some of the finest snorkeling in the islands, you can discover a marvelous underwater world here and have a good chance of finding sea turtles gliding gently alongside you. On the rocks beneath Pinnacle Rock, it’s quite possible to spot some of the quick-as-an-arrow Galapagos penguins; at around 25 centimeters tall, these are members of the second smallest species of penguin in the world. Likewise, you’re likely to see harmless Whitetip reef sharks sunning in these waters. For many visitors, this may turn out to be the best of snorkeling experiences, as the water here is generally clear, without too much surf and full of marine life. This afternoon we will arrive on the northern coast of Santa Cruz Island, where we will visit the long and sandy Bachas Beach, one of the most important nesting beaches for sea turtles. Here you can also find flamingos, Black-winged stilts, sea lions, herons, marine iguanas, and — with a little bit of luck — tiny Galapagos penguins. In addition, this beach is one of the main nesting sites of sea turtles in the Galapagos. A female can lay eggs 3 or 4 times with an average of 70 eggs each, but they then spend 3 to 5 years without breeding. At this paradisiacal site, we will also find the remains of barges that sank long ago; these were once property of the United States Navy when they operated an airbase on Baltra Island during World War II. In fact, the beach got its name because the English word “barges” was hard to pronounce for the local people – hence “Bachas” Beach. You will also have the opportunity to swim on this soft white sand beach or explore the fascinating underwater by snorkeling. Later this afternoon we will visit Santa Cruz Island, the second largest of the Galapagos Islands and located in the center of the archipelago. Located there is Black Turtle Cove, a nesting site for sea turtles, who peak their heads above the surface of the water while fish and other forms of marine life circle below. With luck, the calm water will allow you to see different types of sharks (like the Whitetip reef shark) and schools of golden-colored Mustard rays. There are a number of mangrove forests here as well. Later, we will make a wet landing on Chinese Hat Island, located southeast of Santiago Island. Its name describes the shape of the island, which you will be able to discern from a distance. This island’s landscapes are dominated by volcanic formations and fragile lava tubes. Because of this, it’s very important to stay on the paths. You will encounter a small colony of sea lions and then proceed to hike through this dark, unyielding island of solid rock.
