The Intertwine is an ever-growing network of integrated parks, trails and natural areas that will one day soon be the world's greatest system of its kind. The Intertwine provides unparalleled opportunities to preserve natural areas, open spaces, water and wildlife habitat. The Intertwine reflects our region's passion for quality of life by encouraging recreation, connection to nature, and active transportation such as walking, running and biking. As our urban areas grow denser, The Intertwine promotes the health and happiness we, as citizens of the Pacific Northwest, so dearly value.

A collaborative partnership:

Access to parks and natural areas close to home and work has become increasingly important to our communities’ health and well being. Local agencies and groups have come together to create the Bi-State Regional Trails System Plan. It will be used to identify, plan for and fund the next generation of trail development in the Portland-Vancouver area.
