Bartolomé Island, one of the most iconic destinations in the Galápagos archipelago, is known for its dramatic volcanic landscape and the postcard-perfect view from its summit. Just off the east coast of Santiago Island, this uninhabited islet draws visitors for its unique terrain with lava flows, spatter cones, and a rust-colored cinder cone that rises sharply above the sea. The hike to the top is short but steep, with a boardwalk and 372 wooden steps leading to panoramic views of Pinnacle Rock, turquoise coves, and neighboring islands in the distance.

The island’s moonlike surface tells a geological story dating back thousands of years. Formed by submarine volcanic eruptions, Bartolomé is one of the youngest islands in the Galápagos. Visitors can walk past twisted lava tubes, ash fields, and jagged rock formations, all surrounded by crystal-clear waters. Despite its barren look, the island supports surprising life with lava cacti clinging to black rock and Sally Lightfoot crabs scurrying along the shore in bright flashes of red and blue.

Snorkeling off Bartolomé offers close encounters with some of the Galápagos’ most charismatic marine species. At the base of Pinnacle Rock, snorkelers often swim alongside Galápagos penguins, which are the only species of penguin found north of the equator. Sea lions dart through the water with playful ease, and rays, reef sharks, and schools of tropical fish glide past in the shallow bays. The visibility is excellent year-round, making it a highlight for those eager to explore the underwater world.
