Excellent trip
Reviews: San Diego Harbor Cruise

A Wonderful Experience This cruise was fun, educational and memorable. We went on the 2 hour trip; half explored the northern side and the other half, the southern side of the harbor. As someone who grew up in San Diego and now lives in the Midwest, I saw many things for the first time. “I didn’t know that” was a favorite comment of mine. Wear lots of sunscreen and a hat that won’t blow away. Bring a picnic lunch and water. Be prepared to have a good time and learn a lot.

We were on our way back after seeing hundreds of dolphins, when all of a sudden the whales appeared!
