Located only minutes from downtown Portland is Oregon's only state park within a major metropolitan area. Every day, visitors come to hike or stroll the nature trails through the verdant ravine between Boones Ferry Road and Terwilliger Boulevard in southwest Portland. Cyclists of all ages bike along the paved trail on the park's eastern edge, stopping along the way to admire a trillium. Some people visit Tryon Creek just to sit in the Glenn L. Jackson shelter and listen to the chatter of the jays and squirrels. Others, especially people with mobility-related disabilities, come to enjoy the peaceful setting of the fully-accessible Trillium Trail. Tryon Creek is one of the only streams in the metro area with a run of steelhead trout.
