Tagus Cove is a deep-water bay on the western coast of Isabela Island in the Galápagos archipelago, offering stunning views of Fernandina Island. This historic anchorage has been a popular destination for ships since the 1800s, with ancient graffiti left by whalers and buccaneers still visible on its cliffs. Travellers can hike to the saltwater Darwin Lake, formed inside a volcanic cone, and enjoy panoramic views from the viewpoint. Snorkelling and panga rides along the shoreline provide opportunities to see Galápagos penguins, flightless cormorants, and sea lions.
