Officially named the Hiram M. Chittenden Locks, but known to locals simply as the Ballard Locks, this historic engineering marvel is one of Seattle’s most popular and captivating attractions.
Completed in 1917 by the U.S. Army Corps of Engineers, the Ballard Locks serve a crucial dual purpose: they maintain the water level of the freshwater lakes (Lake Union and Lake Washington) while allowing boats to pass securely between the freshwater shipping canal and the saltwater of Puget Sound.
Beyond its maritime utility, the Locks complex is a stunning 18-acre public park featuring a subterranean fish ladder, a world-class botanical garden, and an interactive visitor center. Whether you want to watch massive commercial vessels drop 26 feet in minutes, spot migrating salmon, or picnic on the grass, here is your complete guide to visiting the Locks.

Getting Here & Parking
The Locks are located at the western edge of Ballard’s commercial core. If you are driving, a paid parking lot is located immediately outside the main gates on NW 54th St. If that lot is full, plenty of paid and free street parking can be found in the surrounding residential blocks. The area is also highly accessible via King County Metro bus routes 17, 40, and 44.
Top Things to See and Do
Watch the Boat Locks in Action
The star attraction is watching vessels travel through the large and small locks. Because Puget Sound’s water level shifts with the tides, the locks act as a water elevator. Watch as captains tie up their boats—ranging from tiny kayaks and luxury yachts to massive 760-foot commercial fishing trawlers—before the water level drops or rises by up to 26 feet. The entire process takes just 10 to 15 minutes.
(Local Tip: You can walk across the lock gates via a system of swinging pedestrian walkways, which also serve as a popular walking and cycling shortcut between Ballard and Magnolia.)
Descend to the Fish Ladder
Built on the south side of the canal, the fish ladder is a critical ecological corridor that allows migrating salmon and steelhead trout to swim upstream from the ocean to spawn in fresh water. Walk down into the underground viewing room, where large glass windows let you look directly into the rushing water to watch these incredible fish fight the current.
When to view migrating fish:
- Sockeye Salmon: July
- King (Chinook) Salmon: Late July through August (Peak season for the largest fish)
- Coho (Silver) Salmon: September through October
- Steelhead Trout: Late February through March
Stroll the Carl S. English Jr. Botanical Garden
Surrounding the north side of the locks is an expansive, English-estate-style botanical garden. Meticulously cultivated for decades by botanist Carl S. English Jr., the grounds boast more than 500 species of trees and thousands of unique flowers from around the globe. Its wide, perfectly manicured lawns are the quintessential neighborhood spot to spread out a blanket, read a book, and watch the boat masts glide by.
Explore the Visitor Center and Concert Series
Before you leave, head into the historic Visitor Center to view interactive exhibits detailing the monumental construction of the Ship Canal. If you visit on a sunny weekend during the summer, the park’s outdoor lawn frequently hosts free live concerts featuring local marching bands, jazz ensembles, and community orchestras.
Tips for a Perfect Visit
- Pack a Picnic: While there is a small concession stand operating on-site during peak summer months, bringing your own lunch or picking up takeout from downtown Ballard to enjoy on the botanical garden lawns is highly recommended.
- Keep Dogs on Leash: Well-behaved dogs are welcome on the grounds, but they must be kept on a leash at all times and are not allowed inside the indoor Visitor Center or the underground fish ladder viewing room.
- Plan Around the Sun: The grounds get highly crowded on beautiful, sunny summer weekends. If you prefer a quieter experience, try visiting early in the morning or on a weekday afternoon.
