It is important to ground ourselves and acknowledge the people whose land we are utilizing ; the Clackamas Chinook, the Wasco-Wishram, the Willamette Tumwater, the Multnomah, and other Chinookan peoples, as well as the Tualatin Kalapuya, the Cayuse, the Molalla and other tribes and bands of the Columbia and Willamette Rivers. It is important to acknowledge the original inhabitants of the land now known as Tryon Creek State Natural Area, and to recognize that we are here because of the sacrifices that were forced upon them. We also remember that we are guests of this land and must do our best to honor the original peoples, through authentic cultural narratives and continued stewardship of the water, the land, and plants that make up this forest community. To follow our acknowledgement with action, we will continue to use our resources to prioritize partnerships with Indigenous tribes, tribal governments, and inter-tribal organizations.
Welcome to Tryon Creek State Natural Area, a 650-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.
The Nature Center is now OPEN, general hours are Sunday - Saturday 9am - 4pm. Come see the newly renovated space.
Bringing a Group to the Park?
We are happy to help you plan your trip to make sure your day goes smoothly. Please click the button below to access some important information about planning your trip, as well as driving directions to the park and instructions for large-group parking.
In order to keep this park as pristine as possible, we ask individuals and groups to abide by the following rules:
Respect the forest by staying on the trails.
Creek beds are fragile. Humans and other animals can cause erosion and hurt fish habitat. Please stay out of creeks.
Dogs are to be kept on leash at all times. Dogs are natural explorers and wish to visit the creek or go off trail. However, even well-behaved dogs disturb the homes of other animals and erode fish and other creek habitat.
Please no collecting. Leave all natural objects where you found them. Many animals live in the forest and may rely on these materials. Please respect their homes, as well as the visitors who follow behind you.
Please dispose of waste appropriately. If paper or other products are brought onto the trails, please bring them back to the Nature Center or Jackson Shelter to dispose of them in the trash or recycling bins. Or take them back out with you.
Bikes are not allowed on the hiking trails as they erode and destroy the trails. A paved bicycle path follows the eastern edge of the park.
By following these rules and sharing them with others, we can go a long way towards ensuring our own enjoyment of the park area and maintain healthy and diverse forest and creek habitats.
We hope you enjoy your visit to the park.
