This is a wonderful snorkeling excursion with the professionals at Ecotours, one of the premier ecotourism companies in Puerto Vallarta. Travel in small groups with great knowledgeable guides and discover an underwater paradise. Learn about the fragile and special ecosystem that makes the Marietas Islands one of the most diverse places on earth, and enjoy snorkeling in the most varied underwater ecosystem in Puerto Vallarta.

Start out from Marina Vallarta with a zodiac ride to Marietas Islands protected marine preserve, where we'll snorkel in two spots, one in each island, and observe the diversity of the underwater ecosystem and rock formations.We'll have lunch on board the boat and learn about the special biology of the area before returning to Puerto Vallarta.
