The Hiram M. Chittenden Locks, often called Ballard Locks, lie at the western end of the Lake Washington Ship Canal in Seattle. They were constructed to raise and lower ships (between six and 26 feet depending on the tides) to allow them to pass between fresh water (Lakes Union and Washington) and salt water (Puget Sound). Operated by the Army Corp of Engineers, the locks are one of Seattle’s most popular visitor attractions and offer a visitor center, fish ladder for salmon, steelhead and other fish and a botanical garden.
Visitor center hours are 10 a.m. to 4 p.m., October through April (closed Tuesdays and Wednesdays) and open daily from 10 a.m. to 6 p.m. May through September. Public tours are available March through September.
