Portland's first official urban wildlife refuge, Oaks Bottom is a 170 acre complex of meadows, woodlands and wetlands on the east bank of the Willamette River just north of the Sellwood Bridge. The Springwater Trail passes through the refuge and a 2 mile unpaved walking path loops around the marsh and connects up to Sellwood Park.
The North Portland Greenway is a partially completed trail system providing access to and along the Willamette River enveloping the north riverfront from the Steel Bridge in downtown Portland to Cathedral Park near the St. Johns Bridge and extending through Baltimore Woods to Kelley Point Park. Visit the npGreenway website for a detailed map of the route.
The trail's second generation Douglas Fir forest is formerly a Camp Fire Girl's Nature Day Camp (Na-Da-Ka).
Mount Talbert Nature Park offers parking, restrooms and a picnic shelter as well as 4.2 miles of hiking trails that loop around the natural area and lead to the summit.
