Photo from the City's park pagePark history
Philip A. Marquam, originally from Baltimore, Maryland, came to Portland via California in 1851. He practiced law and invested in real estate, including the Fulton District, Marquam Hill, and what is now part of Riverview Cemetery. He became a judge in 1862 and a state legislator in 1882. According to The Oregonian on April 2, 1934, Marquam was "one of Portland's picturesque pioneers, prominent in the legal, economic, sporting, educational, and theatrical history of Portland."

Our reading of the calendar
Which facilities count as in season is our model of Portland's year (splash pads and wading pools in summer; fields, gardens and interactive fountains spring through fall; everything else year-round) — not the City's schedule. Check posted hours for pools, splash pads, and restrooms. From 16 weekly catalog snapshots (2026-06-11 to 2026-10-12). "Programs" are distinct titles; "sections" are the catalog's individual records — a swim level at one time slot for one week is one section. Complete through 2026-10; later months fill in as registration opens. Winter counts fill in when winter registration opens.

Condition across all assets
Citywide condition atlasAcross 1 assessed assets at this park, 100% are in poor or very-bad condition (rated 4–5). Pooled from the City's public assessment layers — buildings, bridges, playgrounds, courts, fields, fences, paths and amenities.
This count comes from the City's rated asset layers; the “Public assets” list below is a separate furnishings inventory, so its items and scores are counted separately and the two totals need not match.

Marquam Nature Park includes a portion of the Marquam Trail, a linear trail and connection in the 40-mile Loop system, that starts at Willamette Park, passes over Council Crest, and connects with the Wildwood Trail in Washington Park. This natural area park supports an abundance of native plant species, and contains many trails that wind around Marquam Hill, through trees such as Douglas fir, western hemlock, red cedar, and bigleaf maples. There is a shelter with interpretive displays and maps near the entrance.
This park is maintained with the volunteer assistance of the Friends of Marquam Nature Park. Friends of Marquam Nature Park is a non-profit community-based volunteer organization. They 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.
