The area is surrounded by clear, calm waters with an average depth of approximately 15 feet (4.5 meters), making it one of the best places in Puerto Vallarta for snorkeling. Explore an underwater world filled with colorful tropical fish, rays, sea turtles, and other marine life. During the boat ride, you may also spot dolphins, manta rays, seasonal whales, and seabirds such as pelicans, frigatebirds, and cormorants. You’ll have the opportunity to explore the iconic rock formations and caves by boat before getting in the water to snorkel among the arches and discover the rich marine life beneath the surface.
