Due to its location in the far north of the Galapagos archipelago and because there is no official land visitor site, only a handful of cruises feature Marchena Island in their itineraries. From the dinghy boat, you can appreciate the island’s landscape including some coves and a black-sand beach. The fact that you cannot go onshore is no reason to be sad as the highlight of Marchena is the sea that surrounds it. The deep blue and calm water and Marchena Island’s underwater topography make a great snorkeling site.
