Alderwood State Wayside, State park in Lane County, Oregon.

Alderwood State Wayside is a forest park in Lane County covering about 76 acres along Highway 36 next to the Long Tom River. The site features old Douglas firs, Pacific dogwoods, and bigleaf maples that form a thick forest canopy.

Lane County transferred the land to Oregon State Parks in 1931, and the Civilian Conservation Corps developed picnic facilities around 1935. This early work created the foundation for the park as it exists today.

The wayside's name comes from the alders along the Long Tom River, which crosses the park; the river also draws kingfishers and cutthroat trout. Big Douglas firs, Pacific dogwoods and bigleaf maples shade the picnic ground the Civilian Conservation Corps laid out around 1935. In spring the understory carries trillium, yellow violets, bleeding hearts, ferns and mosses.

The park has toilets, picnic tables, and fishing spots along the river plus hiking trails open year-round. Visitors should know the day-use area operates during standard hours and overnight camping is not permitted.

In spring the forest floor displays yellow violets trillium and bleeding hearts beneath the dense canopy of evergreens and deciduous trees. This seasonal flowering makes the park particularly worth visiting during that time of year.
