These 1- or 2-hour narrated tours lead passengers through San Diego harbor on tours that highlight dozens of San Diego landmarks. You'll see the Star of India, cruise under the San Diego-Coronado Bridge, and swing by a submarine base and an aircraft carrier or two. Guests can visit the captain's wheelhouse for a photo op, and harbor seals and sea lions on buoys are a regular sighting. Whale-watching trips (mid-Dec to late Mar) are a blast; a 2-hour Sunday champagne-brunch cruise departs at 11am, and there are dinner/dance cruises nightly.
