The archipelago consists of four small islets located 6 miles west of the port city of Callao, at the western coast of San Lorenzo Island.

The islands make up a tourist area where it can see a significant amount of sea lions living in its natural habitat.

A colony of over 8,000 thrives on the islands, and the lack of predators has allowed visitors to even swim among the sea lions.

In its coasts can be found gulls, guanayes, zarcillos, boobies, Peruvian pelicans, patillos and red-legged cormorant.
