Photo from the City's park pagePark history
This site is named after an early pioneer family whose original land claim included this 6-acre wilderness area. The Johnson family encouraged public use of its property for recreational purposes, sponsoring 4th of July picnics and fireworks. Nestled in a natural gorge along the banks of Johnson Creek, the site was donated to the City of Portland in 1940.

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.

Tideman Johnson Natural Area on Portland.gov
This page contains information about the Tideman Johnson Natural Area in Portland, Oregon.
Tideman Johnson Natural Area is a peaceful green space in the Ardenwald-Johnson Creek neighborhood in Southeast Portland. It sits along the banks of Johnson Creek and offers neighbors and visitors a quiet place to walk, watch wildlife, and enjoy nature close to home. The land was once part of the Johnson family's early settlement, and they often invited the public to gather here. Their generosity continued when they donated the land to the City in 1940, helping preserve this small but special wilderness for generations to come.
Today, the park is known for its paved and unpaved paths, hiking trails, and its easy connection to the Springwater Corridor. A short boardwalk loop near the creek gives people a close view of the flowing water, native plants, and birds that rely on this habitat. Many people visit the park for bird-watching, since it is home to owls, kingfishers, woodpeckers, herons, and songbirds. In late spring and early summer, the leaves of big-leaf maples and alders are filled with colorful warblers and grosbeaks.
Tideman Johnson Natural Area is also an important place for fish and other wildlife. Over the years, community volunteers and restoration groups have worked together to improve the health of Johnson Creek, where salmon and steelhead return each year. These efforts help support beavers, amphibians, and many other species that depend on clean water and healthy plant life.
