A dry landing deposits you at the beginning of a 2km-long trail that brings you past this postcard-perfect saltwater lagoon. It has twice the salinity of the ocean, and is a tuff cone, like a chimney from the main volcano. The trail leads to the lower lava slopes of Volcán Darwin (1280m), where various volcanic formations and stunning views of surrounding slopes can be observed. There are some steep sections on this trail. A panga ride along the cliffs to Tagus Cove will enable you to see the historical graffiti and various seabirds, usually including Galápagos penguins and flightless cormorants. There are snorkeling opportunities in the cove.
