Park history

Marshall Park was donated to the City of Portland by F. C. and Addie Marshall. According to a letter from the Superintendent of Parks to the City Attorney on May 14, 1947, Mr. Marshall had been devoting himself for the ten years since his retirement "to transforming an abandoned quarry and the marginal ground, some ten or eleven acres in all, into a charming little park which he would like to dedicate without too much fuss to the recreational use of the public." The property was officially accepted as a gift from the Marshalls on June 13, 1951. Additional acreage was added to the original donation in the 1950s.

Marshall Park is primarily a natural area developed with hiking trails located in the middle of a 400-foot-wide canyon. The canyon is a natural drainage basin formed by the west slope of the Palatine Hills, the hills northwest of Mt Sylvania, and by Tryon Creek that runs through it. Within the park is a waterfall framed by rock boulders. One of the notable features of the trail system is a small stone bridge that spans Tryon Creek.

In 2019, a new bridge was installed thanks to funds from the 2014 Parks Replacement Bond.

Counts describe captured listings, not attendance or all activity. No listings captured does not mean the site is unused.

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 and gardens spring through fall, everything else year-round) — not the City's schedule. Check posted hours for pools, splash pads, and restrooms. From 12 weekly catalog snapshots (2026-06-11 to 2026-09-07). "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 2026-09; later months fill in as registration opens. Winter counts fill in when winter registration opens.

How it's holding up

The City's own inventory of what is here and the condition it last recorded for each item. Dates are the source's; old dates mean no newer public assessment, not that nothing has happened since. PP&R does not publish itemized repair costs, so needs appear without dollar figures.

Condition across all assets

Citywide condition atlas

Across 13 assessed assets at this park, 31% 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.

Good · 0Above fair · 2Fair · 7Poor · 2Very bad · 2

Condition is rated 1 (good) to 5 (very bad); no score means not yet assessed and is excluded. Park trees are inventoried separately and not counted here. No repair costs — those aren't published.

Repair ledger

Public data does not currently flag repair candidates for this park. Additional PP&R maintenance exports can be added without changing the page structure.

For closest access to the playground, please use the park entry on SW 12th Drive.

The new bridges are complete and open for use.

Thanks to funding from the voter-approved Parks Replacement Bond, this project will replace a bridge in the Foley-Balmer Natural Area and the Owl Creek Bridge in Marshall Park. Both of these bridges have been out of service for several years, and the new bridges will help reconnect popular SW trails.
