This walk is always so much fun to do as it is fairly flat and you walk along the Willamette River the entire time, just on the two different sides of the river and over the water via the Hawthorne Bridge and the Steel Bridge. Yes, you must dodge some bikers and baby carriages on nice days, but it is not too hard to do. If you walk the entire path, it takes less than an hour to go the approximately 2.2 mile loop. We always park for free on the street on the east side, walk across the Hawthorne Bridge, then do the west side first, often going by the Saturday Market area where we may stop and look, the cross the Steel Bridge to walk back on the east side. From both of the bridges, you can watch speed boats as well as sail boats pass below you. It's a nice feature of Portland that is free to do!
