Watch Your Boat Drop 20 Feet Through Seattle's 100-Year-Old Lock System

The live guide handles the history and context, and you get both indoor and outdoor seating for the full two hours. Arrive 30 minutes early and choose your starting point when you book.

The experience

The sound hits you first: a low mechanical hum as the gates close behind the boat and the water around you starts to drain. You're standing on the deck of a Seattle Locks cruise, and in the next few minutes, your vessel will sink 20 feet from the freshwater level of Lake Union down to the saltwater of Puget Sound, lowered by a system the U.S. Army Corps of Engineers has been running for over a century. It's the kind of thing you've probably seen in photos, but being inside the chamber while it happens (feeling the boat settle as the water level drops) that's different. The Hiram M. Chittenden Locks, also called the Ballard Locks, are the busiest in the nation, and this cruise puts you right in the middle of the action.

The two-hour tour moves through three distinct worlds. You start on Lake Union, the natural lake in the heart of the city, where you'll pass the floating home communities (including the house from Sleepless in Seattle), and see the working shipyard with its massive commercial fishing vessels in dry-dock. Then comes Gas Works Park, the decommissioned coal plant turned neighborhood gathering spot, and the Fremont Bridge, one of the busiest drawbridges in the country, which you'll pass under close enough to feel how tight the fit really is. A live local guide narrates the whole thing, pulling together Seattle's maritime history, the neighborhoods you're moving through, and the practical details of what you're seeing: the fishing boats at Fisherman's Terminal, the industrial heritage of Ballard, the views of the Space Needle and the Olympic mountain range across Puget Sound.

The boat itself has both indoor and outdoor seating, so you can move around depending on the weather and where you want to be for photos. Restrooms are on board, and the whole operation is wheelchair accessible, though if you need crew support for boarding, Argosy Cruises asks that you call ahead. Check-in is 30 minutes before departure, and gates close five minutes before the boat leaves for safety checks. You can choose to depart from Pier 54 on the central waterfront or from AGC Marina on Lake Union, depending on which direction you want to travel through the system. Kids three and under ride free with a boarding pass.
