Sea of Cortez Facts
Nestled between California's 700-mile-long Baja Peninsula and mainland Mexico, the Sea of Cortez is a narrow body of water dotted with pristine archipelago islands. Twelve million years ago the North American Plate shifted, giving life to the crystalline waters favored for their warm weather recreation, commercial fishing and abundant wildlife.

Alternate Names

Costal regions along the northern portion of the Sea of Cortez experience warm temperatures, while areas flanking the southern tip of the sea are tropical.
