The Los Arcos National Marine Park is located just between the beaches of Mismaloya and Las Gemelas. This site has deep tunnels, caves, arches and breathtaking reefs. It is said that the average depth of this place lies between 30 and 1,600 feet (somewhere between 9 and 480 meters), making them the deepest waters of the bay.
Also, this site is protected for the reproduction of various seabirds such as pelicans, bobos and some species of parrots, among others. Similarly, the great diversity of marine life avails scuba diving and snorkeling.
There are several boats cruising the Bay with a stop at Los Arcos to enjoy the scenery and partake of the activities above. Most of these boats continue south to visit beautiful beaches only accessible by sea.
Including a bit of history, many years ago these magnificent natural formations of the bay, were called "Las Peñas". This is where, John Huston decided to film part of the movie "Night of the Iguana" in the early 60's.
