Duwamish River

Located in Seattle's South Park neighborhood, this public boat ramp sits beneath the 1st Avenue South bridge off South River Street, providing convenient access to the Duwamish River. The ramp is designed for small to medium-sized vessels, making it ideal for kayakers, canoeists, and recreational boaters. There is no launch fee for this facility, and the quiet, relatively secluded setting offers a good starting point for exploring the river's urban waterway.

Paddlers should be aware that the Duwamish River flows toward Puget Sound, offering opportunities for downstream exploration, though the distance to open marine waters is considerable. The river's tidal nature and urban setting mean that water conditions can vary with tide cycles. The South Park area nearby offers additional amenities including Duwamish Park with river views, picnic facilities, and accessible pathways. Before launching, check current conditions and be familiar with tidal patterns, as the Duwamish is influenced by saltwater tidal movements from Puget Sound.
