Said to be the most-visited and most-photographed destination in the Galapagos, diminutive Bartolomé Island has a total land mass of only one-half of one square mile and no human inhabitants. The island, just off the east coast of Santiago Island, is punctuated by the iconic Pinnacle Rock.The main vent of the volcano here is Bartolomé itself. Hike a planked walkway and climb more than 300 wooden steps to reach the island’s 374-foot summit and be rewarded by some of the archipelago’s most spectacular views, including pristine Sulivan Bay and neighboring Santiago, North Seymour, Baltra, Santa Cruz and Rabida islands.
