context_page_description: Mona is the third-largest island of the Puerto Rican archipelago, after the main island of Puerto Rico and Vieques. It is the largest of three islands in the Mona Passage, a strait between the Dominican Republic and Puerto Rico, the others being Monito Island and Desecheo Island. It measures about 7 miles by 4 miles, and lies 41 mi west of Puerto Rico, of which it is administratively a part. It is one of two islands that make up the Isla de Mona e Islote Monito.
  The island is managed as the Reserva Natural Isla de Mona. There are no native inhabitants; only rangers and biologists from Puerto Rico's Department of Natural and Environmental Resources reside on the island, to manage visitors and take part in research projects.
context_section_description: Around 200 caves are on the island with thousands of native art designs and the marks and names made by early Spanish explorers.
