San Pedro Island: sea-lion boat diving off San Carlos.
San Pedro Island is a Sea of Cortez boat-diving and snorkeling destination off San Carlos, best known for sea-lion encounters, rocky coves, and clear water that makes wildlife watching the main event. It suits organized trips more than casual shore visits, and the reserve setting helps keep the experience feeling wild rather than developed. The best visits are the ones that match the boat window and keep a respectful pace around the animals.
