This coastal spot in San Diego County is one of the most picturesque in the state. Explore the Seven Caves, snorkel with Leopard Sharks and catch a glimpse of a sea lion. SD Expeditions takes divers and snorkelers to see the best that the area has to offer under water. Seals lay on the sand at the Children’s Pool Beach. Another place you can almost always see them is at La Jolla Cove.
