Estero del Soldado
This is a small coastal lagoon located in-between San Carlos and Guaymas, surrounded by mangroves. This water body is approximately 350 acres of area and about 1 meter deep. Despite its small size, this tideland shelters 85 different species of fish, 80 of birds, and a little more than 150 species of marine invertebrates. For this reason, the state government authorities recognized the importance of this site and took measures to preserve it from contamination, so it is now considered a protected natural area.
