It is the mouth of the San José River that runs for almost 30 miles from the mountains of southern Baja California to the edge of the sea. Here a lagoon is formed where fresh and salty waters mix. Only a sliver of white sand separates the fresh water estuary with the salt water of the Sea of Cortez

The estuary is a 140 ha sanctuary with a unique ecosystem. On the slopes you can see cacti and more than 100 species of birds.

In order to preserve this natural wonder, a series of ecological measures have been implemented.
