A natural landmark of Banderas Bay, the Marieta Islands are one of the most important places for marine bird watching in México and the eastern Pacific tropics, as well as being a shelter for countless varieties of marine species. This wildlife refuge is a protected natural zone, and its characteristics make it a unique place worthy of visiting and respecting.Volcanic protected islands The islands were formed during the Cretaceous era by volcanic activity that created ragged formations, ideal places to shelter life. Although their names are somewhat different, the two islands that make up this archipelago (one round and one long) have basically the same formations, dominated by vast caves and cliffs.
Marieta Island on Wikipedia
The Marieta Islands (Spanish: Islas Marietas) are a group of small uninhabited islands a few miles off the coast of Nayarit, Mexico. They are very popular tourist destinations because of the abundant marine life populations due to the islands being protected from fishing and hunting by the Mexican government.
The Marietas Islands were originally formed many thousands of years ago by volcanic activity, and are completely uninhabited. The islands are about an hour long boat ride west-northwest from the coast of Puerto Vallarta and are visited daily by hundreds of tourists, yet no one can legally set foot on the islands. In the early 1900s the Mexican government began conducting military testing on the islands because no one lived there. Many bombings and large explosions took place on the islands causing amazing caves and rock formations to be created. After a massive international outcry, started by scientist Jacques Cousteau in the late 1960s, the government eventually decided to label the islands a national park and therefore protected against any fishing, hunting or human activity.
