The Marieta Islands, a Natural Protected Area, a marine life sanctuary.
On the north end of the bay, near the point known as Punta de Mita and just a few miles off shore, the Marietas are an archipelago consisting of four small uninhabited rocky islands, almost all of which are of difficult access.
They shelter sea and land fauna, a breeding colony of Blue footed and Brown boobies. In the surrounding waters, numerous species of fish and marine mammals find shelter and prosper.
In the winter months, humpback whales visit the waters on Banderas Bay, and in particular the area near the Marietas, to mate and to give birth to their calves.
The Marietas, therefore, are one of the main natural attractions of the bay.
