Conservationist Jaques Costeau once called the Sea of Cortez "the largest natural aquarium in the world" and the local government has taken steps to protect the vast biodiversity found here by creating marine parks such as Nopolo Bay National Marine Park. And one of the best ways to enjoy this aquatic icon is aboard a glass bottom boat. Once you venture out onto the cerulean waters, you'll witness the vast variety of sea life that habitats the marine park from the comfort of your own seat. Keep your camera at handy and you may also see an aquarium full of fish, dolphins, porpoises, whales (in season), and many different types of sea birds including the fisherman's eagle, blue footed boobies and more, which are quite common to the area.
