If you have been to Boston before and want to see it in a new way this is the trip for you. What an adventure riding in the Duck boat. We traveled around seeing different sites and then we ventured into the Charles River to see Boston from a different vantage point. Our guide "Dirty Waters" kept up a constant banter of facts and fun information to make the tour even more fun. The tour last about 80 minutes and was just the right amount of time.
