This is a short portion of the The Foster Foundation Trail in downtown Seattle and is 1.2 miles long out-and-back. The trail is highly trafficked and runs directly along Elliott Bay, passing through a small section of Olympic Park. This trail also runs parallel to the Elliott Bay Trail, thus they're almost an interchangeable path if you follow this trail.
The trail is paved and mostly flat with benches along the water and views of downtown, Elliott Bay, and the mountains in Olympic National Park on days with clear skies. Dogs and biking are both allowed.
