Getting on to the water is a great way to see Seattle from a different angle. I've written about the half-hour excursion to Bainbridge Island several times before (here, here, here, and here), but another popular way to get on the water in Seattle is provided by Argosy Cruises. As part of my effort to tour while local, I tried out their Lake Union and Ballard Locks Cruise.
Kenmore Air just across from the Museum of History and Industry. In the photo above, you can also see the Virginia V which is one of the last remaining mosquito fleet steamers.
This particular tour goes for $41. If you are visiting and looking to save some money, Washington State ferries provide another way to get on the water. At $8 per person on foot round trip (there is no fare headed west for foot passengers), it doesn't show off the city to the same degree but does lend itself to afternoon trips to Bainbridge Island. A middle option that still offers a guided tour with less cost and time commitment is the harbor cruise that Argosy offers for $24 a person. It is their most popular tour and you still get the views of the mountain, sound, and city. Either way, seeing the city from the water is sure to give a unique perspective on the city and be a fun afternoon.
