Disembarking by Zodiacs, visit Black Turtle Cove and its inlets surrounded by mangrove swamps. Here you may observe pairs of mating sea turtles, white-tipped reef sharks, and golden rays. Following lunch, visit Cerro Dragon and look for Darwin finches, Galapagos flycatchers, Yellow warblers, Audubon shearwater, and the brilliantly colored endemic land iguanas.
On Fernandina we land at Punta Espinoza where hundreds of marine iguanas, the largest colony in Galapagos, bask in the sun along the rugged shoreline. Observe sea lion harems and flightless cormorants while Galapagos Hawks soar overhead. After lunch, disembark at the base of Alcedo Volano, at Urbina Bay on Isabela Island. Here we find 4 miles of exposed coastal seabed and remnants of marine life, brought to the surface during a dramatic uplift in 1954, following a volcanic eruption. You may observe nesting brown pelicans and flightless cormorants here, as well as giant marine iguanas. Later cross the Bolivar Channel where we often spot whales and dolphins riding the bow wave.
