Splash down into the San Diego Bay off Shelter Island, where you begin your water-tour segment of the journey. As the SEAL travels through the north of end of the Big Bay, keep your eyes peeled for a chance encounter with a California Brown Pelican, the petite Least Tern, the majestic Blue Heron, or perhaps a sea lion or two. You will also hear about the early fishing industry. The Big Bay provides views of Point Loma, home to the Cabrillo National Monument, Naval Air Station North Island, the Point Loma Submarine Base, and the Scripps Institution of Oceanography. The return trip takes you, once again, back up on land where you will return to your starting point via Harbor Drive while you pass the Maritime Museum and the Cruise Ship Terminal.
