Friends of Marquam Nature Park is a non-profit community-based volunteer organization. We work in partnership with Portland Parks & Recreation and others to conserve, maintain and enhance the historical, natural, and recreational resources of Marquam Nature Park and to educate the public about the park's unique natural and cultural history.
Marquam Nature Park is a Portland Parks & Recreation Natural Area. Comprised of over 193 acres of undeveloped land and over 5 miles of hiking trails it is the third largest park in Portland. Minutes from downtown and easily accessible by public transportation, the park provides excellent hiking and running opportunities, an escape from city life, forested scenic views and native habitats that help to enhance the region's air and water quality. Marquam Trail, an important 7.0 mile link in the 40-Mile Loop trail system as well as being the "Trail" portion of the 4T, runs through the park and provides a connection to other trails and natural areas throughout the metropolitan area.
