Discover this magnificent snorkelling site and watch Puerto Vallarta from the sea!
Los Arcos is a group of five islets, between 15 and 150 feet high, located in the waters of Bahía de Banderas, about 6 miles south of Puerto Vallarta city. Three of these islets have natural tunnels from which their current name comes; once they were known as Las Peñas.

This site presents a great scenic beauty, because among its rocks and vegetation nest and rest various marine and coastal birds such as brown pelicans, magnificent frigatebirds, seagulls, herons, among others. It also has an important diversity of marine life, since dozens of fish species live here, such as the Moorish idol, the king angelfish, the giant damselfish, balloon fish and even manta rays; also, we can observe corals, sponges and many other marine invertebrates and, with a bit of luck, sea turtles can be seen resting among the bottom rocks.
