Linnton, located between Forest Park and Sauvie Island, is a riverside and industrial Portland neighborhood with working waterfront views and a wooded hillside backdrop. The neighborhood’s character concentrates along NW St. Helens Road near the Linnton Store, where freight traffic, river air, and a small cluster of local stops set the tone. The Linnton Store anchors daily routines, while the Portland Yacht Club and the Linnton Community Center add long-running gathering places. Housing ranges from modest mid-century homes to newer builds perched above the road, many oriented toward the Willamette. The shoreline reads as docks, marinas, and river industry, with pockets of quiet streets climbing into trees. Forest Park trailheads and the river corridor shape an outdoors-forward rhythm without leaving the city.
