The refuge peaks in winter.
Most visitors think of the Tualatin River National Wildlife Refuge as a spring or summer destination, but November through February is actually its peak season. Wintering waterfowl can number in the tens of thousands, and bald eagles patrol the wetlands, all about 10 minutes from 22379 SW 107th Ave.
The refuge sits at 19255 SW Pacific Hwy in Sherwood, just south of Tualatin, and it is open every day of the year from dawn to dusk. The Visitor Center runs Tuesday through Sunday, 10 AM to 4 PM, and admission is free. As the rains return and temperatures drop, refuge staff flood portions of the wetlands, turning the open water into one of the Willamette Valley's most reliable winter birding spots.
Bird numbers are greatest from October through May, with up to 50,000 waterfowl reported on the refuge during winter months. Dabbling ducks such as mallards, northern pintails, and American wigeons gather on the open water, and bald eagles become regular winter visitors, hunting from snags along the river. More than 200 species visit the refuge over the course of a year, so even returning regulars see something new.
What to expect
A quiet season, busy skies.
Waterfowl on the move
Mallards, pintails, and wigeons
Winter residents include mallards, northern pintails, and American wigeons, with flocks lifting off the water at once when a raptor passes. Late afternoon light over the pools is the classic sighting window.
Bald eagles
Regular winter visitors
Bald eagles are a dependable winter presence, perching in the tall trees along the river and working the wetlands for fish and waterfowl. Binoculars help, but their size makes them easier to spot than most winter birds.
Trails that stay open
Year-round out-and-back route
The year-round out-and-back trail out to the wetland overlook stays open through winter, while the seasonal loop closes around October 1 each year to protect habitat. Sturdy waterproof shoes are the main requirement.
Cold-weather comforts
Visitor Center warmth
The Visitor Center, open Tuesday through Sunday from 10 AM to 4 PM, offers exhibits, wildlife viewing tips, and a warm place to warm up between trail loops. Restrooms and parking make it an easy family stop.
