Hiking

The Twanoh State Park Loop offers a delightful and accessible forest experience, tracing the gurgling Twanoh Creek through a vibrant ecosystem of mature Douglas firs and cedars. You'll wander through wide expanses of ferns, ascend through multiple forest levels, and even catch occasional peekaboo views of the Hood Canal. It's a diverse journey that feels much more secluded than its location suggests, perfect for a quick nature immersion.

This easy 2.0-mile (3.2 km) hiking route involves 374 feet (114 metres) of elevation gain, typically taking just under an hour to complete. The trail's footing is well-maintained, making it a good option even in winter. Parking is readily available at Twanoh State Park, and no special permits are needed, so you can easily plan a visit any time of year.

Twanoh State Park holds historical significance as one of Washington's oldest state parks, featuring remarkably preserved Civilian Conservation Corps (CCC) architecture. The trail itself provides a unique opportunity to observe salmon spawning in the fall along Twanoh Creek and explore a forest with large trees spared from 1890s logging. It's a quiet gem, despite the park's popularity, offering a peaceful escape.
