Access the wildlife area by the Interlakes Trail (paved). A portable toilet at the trailhead; a parking lot with restrooms is 0.25 mi from the entrance. The path begins at the park entrance, and runs 0.5 mi through cottonwood forest and riparian brush to two observation blinds. In winter, along with sparrows including Golden-crowned and occasionally Lincoln’s Sparrows, expect to see many geese and ducks, notably Canvasback and Redhead. Hundreds of Great Egret show up as water levels are lowered in fall. Migrant shorebirds use the area in summer and fall. Spring and summer bring songbirds such as Black-headed Grosbeak to the forest. Bald Eagle nest on site. On warm days, you may see Western Painted Turtles basking in the backwaters. Paddling is best in spring and early summer when the water level is still high enough for good access.
From Portland, take I-5 N to Exit 307, and follow signs for Marine Dr W. The park entrance is about 1.5 mi down on the L.
