Tin Mine is a spot where you can peek into an old tunnel and imagine the history behind it. This fun, varied hike on Green Mountain takes you through lush forest, past small waterfalls, and alongside a quiet beaver pond—making the journey as rewarding as the destination.

Tamanowas Rock Sanctuary is a protected area featuring Tamanowas Rock, a 150-foot-high geological formation with caves and crevices, considered sacred by the Coast Salish peoples. The trail gets steeper and narrower as you get closer to the rock. The sanctuary is privately owned by the Jamestown S'Klallam Tribe, so visitors are welcome but should be mindful of its cultural importance. It’s also a great spot for fungi enthusiasts to explore.

Cougar Mountain Park spans nearly 3,000 acres, featuring over thirty-five miles of fantastic trails winding through second-growth forests, streams, wetlands, cliffs, and historical mining caves.

Most trails are mainly for hikers; however, some allow horseback riding, so keep an eye out for equestrians as you explore this beautiful area.
