I've had the chance to go to Portland, OR for almost a week to participate in the Embedded Linux Conference North America 2017 and took some days off to discover the city, as I did for ELCE 2016 in Berlin.
Walk on Waterfront-Park Trail
Portland is also known as `the City of Roses' (Source) and hosts the International Rose Test Garden. Unfortunately at this time of the year, the roses haven't (of course) bloomed yet.
Japanese Garden
Hiking Mount Tabor
Crystal Springs Rhododendron Garden (still with unbloomed flowers)
