This was our first time visiting Mt. Tabor Park (), which is located on a cinder cone in SE Portland (check out these two PDFs to learn more about the geology of Portland, including its volcanic features: Volcanoes of the Portland Area, Oregon  and Portland, Oregon, geology by tram, train, and foot ). Along with numerous trails and views to enjoy, it has several city reservoirs that make for an interesting outing. (photos)
