Nature certainly has its miracles and you can see one of its highlights at the Chittenden Locks & Fish Ladder, locally known as the Ballard Locks, where you can see salmon fighting their way to their spawning grounds in the Cascade headwaters of the Sammamish River, which feeds Lake Washington.
Watching the salmon climb the fish ladder is pretty exciting. You can watch the fish from underwater glass-sided tanks or from above (nets are installed to keep salmon from over-leaping and stranding themselves on the pavement). In the past, the fish runs at Chittenden Locks & Fish Ladder have attracted sea lions that try to swallow the salmon as they go by.
On the northern entrance to the Chittenden Locks & Fish Ladder is the Carl English, Jr., Botanical Gardens, a charming arboretum and specimen garden. Trails wind through gardens filled with mature trees and flower gardens. Flanking the gardens is a small museum and visitors center documenting the history of the locks.
The Chittenden Locks & Fish Ladder, also known as the Ballard Locks, is located about 15 minutes north of downtown Seattle. To get here, follow Elliott Avenue north along the waterfront from downtown Seattle; after crossing the Ballard Bridge, drive west on Northwest Market Street. The best time to visit is during spawning season, from mid-June to September.
