Tryon Creek State Park

Tryon Creek is a 670-acre-plus natural day use area located between Portland’s metropolitan area and the city of Lake Oswego. The park has 8 miles of hiking trails, 3.5 miles of horse trail and a 3-mile paved bicycle trail.

Bicycle Path

The 3-mile paved bicycle path parallels Terwilliger Boulevard on the east edge of the park, from Boones Ferry Road to State Street (Oregon Highway 43) in Lake Oswego. It is part of the Portland metropolitan area bikeway system 40-mile loop.

The Trillium Trail

The .37 mile barrier-free Trillium Trail is designed for people of all abilities. It has paved pathways, resting benches and viewing decks. Trail features are identified along the way.

Horse Trails

The horse trails have the greatest variation in grade: each begins near the ridgeline and travels down to the creek and back. The trail surface is packed gravel, which can support horse traffic even in wet weather. From the equestrian parking area, the North Horse Loop is 2.1 miles and the West Horse Loop is 3.1 miles.

The Nature Center

Visitors can obtain park information, purchase gifts and enjoy interpretive exhibits and programs at the Nature Center and nearby Glenn Jackson Shelter. Many park events are sponsored by the Friends of Tryon Creek, a non-profit citizens’ organization dedicated to the conservation of the park’s natural environment. For more information, call the Friends at 503-636-4398 or online at

Three 1/2 mile loops (Maple Ridge, Center and Big Fir) surround the Nature Center. Walking down to the creek involves a 125 foot elevation change. Park trails are maintained for year-round hiking. Hiking trails in the park can be muddy during wet weather.
