SANTA CRUZ HIGHLANDS
Los Gemelos (The Twins) is a visitor site in the Santa Cruz highlands. Found some 15 kilometers northwest of Puerto Ayora, the road leading from Puerto Ayora in the south of Santa Cruz to Itabaca in the north dissects the twin pit craters. Pit craters are formed when the roof of an underground void collapses. The smaller pit crater is on the eastern side of the road, while the larger one is on the western side. See from above, the two openings in the ground are not at all identical. Their layout might imply an elongated magma chamber or a lava tube leading further west and the larger twin actually having formerly been two small pit craters whose connecting wall collapsed as well. Trails through a Scalesia forest not only give access to good views of the pit craters, but also permit to observe some of the smaller land birds. Vermilion Flycatchers, Yellow Warblers, Galapagos Doves, Medium Ground Finches and several other finch species can often be seen there.
