Surely a natural icon of Banderas Bay, the Marietas Islands are one of the most important nesting sites of seabirds in Mexico and eastern tropical Pacific, also housing many other marine species.
Marieta Islands were caused by volcanic activity during the cretaceous era, getting fancy shapes, the two islands of this archipelago (Round Island and Long Island) have virtually the same shape, dominated on the surface and underneath with a variety of caves and cliffs.
After years of scientific research and an intensive effort to provide legal protection to the archipelago, was finally declared a “Marietas Islands National Park” in 2005, with almost 1,400 hectares of land to be an important nesting area, shelter, reproduction and transit of at least 92 species of waterfowl, underwater, resident and migratory.
It is estimated that in these islands is located the largest population of the iconic global brown bobo bird (Sula leucogaster) and with them you can see the beautiful blue-footed bobo bird, which also nests in the Galapagos Islands.
That is why it is not allowed to “step on” the islands, and human routes should be limited to sightseeing, the beach and water activities like diving, kayaking and snorkeling.
If this was not enough, during winter you can hear the amazing songs of humpback whales, who use the islands as a natural shelter against predators and ocean currents.
