Tryon Creek State Park
Finding a 658-acre old-growth forest in the middle of a major metropolitan area is rare, but that’s exactly what you’ll discover at Tryon Creek State Natural Area. Located just 15 minutes south of downtown Portland, it holds the unique distinction of being Oregon’s only state park located entirely within a major city.
Established as a haven for both wildlife and city dwellers, Tryon Creek is a lush, vibrant canyon where towering Douglas-firs, Western redcedars, and blooming trilliums create a dense canopy over a network of pristine woodland trails. Whether you are looking for a quick morning trail run, a family-friendly nature walk, or an afternoon horseback ride, this urban oasis provides an immediate escape into the wild.

Exploring the Trails at Tryon Creek
The defining feature of Tryon Creek State Natural Area is its extensive, multi-use trail system. Because of the dense forest canopy, the park stays remarkably cool in the summer and serves as a green lung for the city of Portland.
Hiking and Trail Running
There are exactly 8 miles of dedicated hiking trails weaving through the canyon. The paths are well-maintained year-round, crossing the creek on eight different picturesque wooden bridges. Popular routes include the mostly-flat Old Main Trail (0.6 miles) and the steeper, more challenging Iron Mountain Trail (1 mile). Be prepared for muddy conditions during the classic Oregon winter rains!
Equestrian Trails
Urban horseback riding is a rarity, but Tryon Creek offers 3.5 miles of packed gravel equestrian trails. The North Horse Loop (2.1 miles) and West Horse Loop (3.1 miles) traverse the park’s ridgelines before dipping down near the creek. The park features a dedicated, pull-through equestrian parking lot specifically designed for horse trailers.
Paved Bicycling Path
While mountain biking is strictly prohibited on the dirt hiking trails to prevent erosion, cyclists can enjoy a 3-mile paved bicycle path that runs parallel to Terwilliger Boulevard on the eastern edge of the park. This path connects Lake Oswego to Portland and is a crucial segment of the Portland metropolitan area’s 40-Mile Loop bikeway system.
The Trillium Trail (ADA Accessible)
The park is famous for the Trillium Trail, a 0.3-mile, fully paved loop that is 6-feet wide with a gentle, unified slope. Designed for wheelchairs, strollers, and all abilities, this trail is lined with interpretive signs and resting benches. It is spectacular in late March and early April when the namesake white Trillium flowers bloom profusely across the forest floor.
The Tryon Creek Nature Center
Before hitting the trails, stop by the Nature Center located at the main Terwilliger Boulevard entrance. Operated in partnership with the non-profit Friends of Tryon Creek, the center is the educational hub of the park.
Inside, you’ll find beautifully curated interpretive exhibits detailing the natural history of the canyon, a small gift shop, and park rangers ready to help you plan your hike. The center is also the starting point for numerous guided nature walks and educational programs run throughout the year.
Wildlife in the City
Despite its urban surroundings, Tryon Creek is a thriving ecosystem. Over 50 species of birds, including pileated woodpeckers, great horned owls, and various songbirds, call the canopy home. Down near the creek banks, keep an eye out for foraging beavers. The creek itself is a vital urban watershed that still supports small, struggling runs of native steelhead trout and coho salmon.
