About this site
San Pedro Nolasco Island sits in the Gulf of California a few kilometers off the Sonoran coast near San Carlos and Guaymas, and dive sites around it are reached by boat from those towns. The island's steep, rocky shoreline drops into deep water typical of the central Gulf, making it a common stop for operators working out of San Carlos.
