Ballard Locks

Officially known as the "Hiram M. Chittenden Locks", this pair of boat locks are some of the busier locks in the country, as ships traveling between Puget Sound and Lake Union or Lake Washington must traverse these locks. There are two locks; one for large ships and one for small ships, in addition to a salmon run to allow salmon to climb the 22 feet between sea level and the level of Lake Washington.

In addition to the locks themselves, the northern side of the locks (which includes about 50 spaces of parking) also hosts the Carl English Botanical Gardens.
