About Greenbushes State Forest

Greenbushes State Forest is a diverse woodland area in southwestern Washington, offering extensive opportunities for hiking, wildlife observation, and outdoor recreation amid mixed forest landscapes.

Wilderness Landscape & Natural Heritage

Greenbushes State Forest covers a portion of the coastal foothills in southwestern Washington State, providing visitors with a mix of coniferous and deciduous forests, meandering streams, and varied topography. The area is characterized by Douglas fir, western hemlock, cedar, and occasionally broadleaf species like red alder and bigleaf maple. This forest is part of the larger ecosystem supporting an abundance of wildlife including black-tailed deer, various bird species, and smaller mammals. Historically, the area supported Native American groups and later contributed to the timber industry, though it has since shifted focus to conservation and recreation. Greenbushes State Forest features an extensive trail network used for hiking, mountain biking, and horseback riding, attracting outdoor enthusiasts looking for moderately challenging routes with scenic views. Several small streams running through the forest contribute to local watershed health and provide habitat for amphibians and aquatic insects. The forest’s remote access and lower visitor density make it ideal for solitude and nature appreciation. Visitors often explore the area for bird watching, photography, and seasonal hunting. While there are no developed campgrounds within the forest itself, dispersed camping is permitted following state forestry guidelines. Land management prioritizes sustainable practices balancing recreation and ecosystem protection, supporting healthy forest regeneration and wildlife habitats. Through its natural diversity and recreational offerings, Greenbushes State Forest serves as a resource for both local communities and outdoor adventurers.
