Marchena is the largest of the so-called northern islands here in Galapagos. Despite most of the current volcanic activity being concentrated to the western islands Isabela and Fernandina, Marchena suffered a volcanic eruption in 1991 - the first for over a century.
Marchena has no land visitor sites, and it's even rare for scientists or National Park wardens to visit, so it's one of the islands least touched by humans at present. The coastal caves and rocks play host to Galapagos Fur Seals, and sea lions.
