About this site
San Pedro Nolasco Island sits in the Gulf of California a few kilometers off the coast near San Carlos and Guaymas, Sonora, rising steeply from deep water. The island is uninhabited and protected as a nature reserve, and its surrounding waters are known for rocky drop-offs and sea lion colonies that draw divers from the Sonoran mainland.
