Parks & Public Art Walk - YRE 1400 - 10km - rated 1+. If you enjoy city parks and lots of Public Artwork, bakeries, a bookstore plus shopping then you will enjoy this walk. It takes you past new and old, small but interesting, city parks. Then you head towards the Columbia River and walk along the path that connects to downtown Portland. On the return trip you go over a foot bridge and by the train station before heading to downtown Portland and the bakeries and Powell's bookstore. Great walk to get a taste of what Portland is about.
