Narborough Island

(Local Name: Fernandina) Fernandina, the third largest island, is a single volcano with a maximum elevation of 1400 m (4500 ft). The most recent eruptions occurred in 1988, 1991, and 1995, leaving a caldera 344m (1100 ft) deep.

There is a visitor site at Punta Espinosa, across the channel from Tagus Cove on Isabela. Two trails from the landing site lead through the lava fields. Common sights on the island include marine and land iguanas, tortoises, Galápagos penguins, hawks, sea lions, and a variety of sea birds, including flightless cormorants.
