There is a river running through the middle of Tualatin, and most people barely notice it.
That sounds dramatic, but it’s surprisingly true. The Tualatin River winds through town on its way to join the Willamette, passing parks, greenways, wetlands, and some of the prettiest riparian habitat in the Portland metro — and unless you’ve specifically gone looking for it, you might drive over the bridges every day without ever walking down to the water.
May changes that. In May, the river corridor comes alive with wildflowers, nesting birds, and the kind of lush Pacific Northwest green that makes you forget you’re five minutes from I-5. If you live in or around Tualatin and you haven’t walked the river trail in spring, this is your invitation.
🏞️ The River Trail: What It Is and Where It Goes
The Tualatin River greenway isn’t a single continuous trail (yet — the city has been working on connecting the gaps for years), but the existing sections add up to several miles of walkable, bikeable path along the river and its tributary creeks. The main segments include:
- Tualatin Community Park to Brown’s Ferry Park: The most developed section, following the river’s south bank through the heart of town. Paved, flat, and shaded by mature cottonwoods and Oregon ash. About 1.5 miles one way.
- Tualatin River National Wildlife Refuge access (Atfálat’i Park): The northern trailhead off SW Tualatin Road connects to the federal wildlife refuge, which protects 1,856 acres of riparian and wetland habitat. The refuge trails are gravel and boardwalk, open seasonally.
- Hedges Creek Wetlands: A 38-acre wetland preserve off SW Martinazzi Avenue with a loop trail and boardwalk. Small but surprisingly rich with birds and native plants.
- Jurgens Park to Tualatin River Greenway: A newer section along SW Boones Ferry Road connecting Jurgens Park to the river corridor. Paved and family-friendly.
🌺 What’s Blooming in May
May is peak wildflower season along the Tualatin River, and the species you’ll see depend on which part of the corridor you walk:
Riparian banks and floodplain (Community Park to Brown’s Ferry):
- Oregon iris (Iris tenax) — purple-blue blooms in sunny openings along the trail edge
- Red clover and white clover — carpeting the mowed meadow sections
- Wild rose (Rosa nutkana) — pink, fragrant, and blooming in thickets near the water
- Snowberry in flower — small pink-white blossoms on the shrubs that produce the white berries in fall
- Red-flowering currant — the tail end of its bloom, with clusters of pink-red flowers still hanging on some bushes
Wetland areas (Hedges Creek, Wildlife Refuge):
- Camas (Camassia quamash) — the signature blue-purple wetland bloom of the Willamette Valley, peaking in early-to-mid May. The refuge meadows can turn blue with camas in a good year.
- Western buttercup — bright yellow, scattered through wet meadows
- Checkermallow (Sidalcea) — pink spikes in the wetter meadow areas
- Skunk cabbage — the enormous yellow spathes are past peak by May, but the massive leaves are at their most impressive
Forest understory (shaded sections):
- Trillium — the three-petaled white blooms (turning pink as they age) are finishing their season but still visible in early May
- Sword fern fiddleheads — unfurling into full fronds throughout the month
- Oregon grape — bright yellow flower clusters on the low shrubs, turning to blue berries later in summer
🐦 Birds You’ll See (and Hear)
May is nesting season, and the river corridor is full of birdsong. Even if you’re not a birder, you’ll notice:
- Great blue herons — standing motionless in the shallows or flying overhead with their prehistoric wingbeats
- Red-winged blackbirds — the males perch on cattails and sing their territorial “conk-a-ree” call nonstop
- Osprey — nesting on platforms near the river, diving for fish
- Cedar waxwings — sleek, masked birds that travel in flocks and love the berry bushes along the trail
- Song sparrows, Bewick’s wrens, and black-capped chickadees — the constant background chorus
🚶 Best Walk for Different Moods
- Quick lunch-break walk: Tualatin Community Park loop (0.75 miles). Flat, paved, shaded, and right in town.
- Proper morning stroll: Community Park to Brown’s Ferry Park and back (3 miles round trip). The prettiest stretch, best before 10 AM when the light comes through the cottonwoods.
- Wildflower mission: Tualatin River National Wildlife Refuge (1–3 miles). Camas meadows, wetland boardwalks, and the most diverse bloom on the corridor. Check refuge hours before you go — seasonal closures apply.
- Family outing with kids: Hedges Creek Wetlands loop (0.5 miles) plus Jurgens Park playground. Short, contained, and the boardwalk gives kids something to explore.
- Mother’s Day walk: Any of the above, honestly. The river corridor is beautiful in mid-May and pairs perfectly with brunch in town afterward. We wrote a full Mother’s Day playbook if you want to build the whole day around it.
💡 Why This Trail Deserves More Attention
Tualatin gets overshadowed by flashier Portland-area nature destinations. People drive to Forest Park, Tryon Creek, or Powell Butte — all excellent — and skip the river running through their own town. But the Tualatin River corridor has something those places don’t: it’s genuinely local. You can walk it on a Tuesday morning before work, or after dinner on a long May evening, without driving anywhere or competing for parking.
The spring walks guide we wrote earlier covers the broader area — Bridgeport, Stafford, Lake Oswego. This is the deeper dive into Tualatin’s own backyard, and it’s worth the closer look.
💐 Finish with the Other Kind of Bloom
The wildflowers along the river are beautiful — and they should stay along the river. (Please don’t pick native wildflowers, especially the camas.) But if the walk puts you in that mood where you want to share something beautiful with someone you love, that’s exactly what a florist is for.
At tualatinflorist.com, we deliver same-day across Tualatin, Sherwood, Wilsonville, Lake Oswego, Tigard, and the surrounding area. Order from the trail if you want — we’ll have flowers waiting when you get home. 🌿💐
