Best Hidden Trails in the Pacific Northwest

Old-growth giants, mossy waterfalls and forgotten fire lookouts.

The Cascades and Olympics hide more old-growth than the famous parks would suggest. These are the trails that don't make AllTrails' top 10 — and the trees, springs and lookouts you find at the end of them are why locals keep coming back.

Grove of the Patriarchs

Ancient Tree

Thousand-year-old Douglas firs and red cedars on a river island in Mount Rainier.

Park Butte Lookout

Viewpoint

Restored 1930s fire lookout above the meadows. Sleep there free if you arrive early.

Soleduck Hot Springs path

Spring

The wild upstream pools — past the resort — are free and usually empty after sunset.

Quinault Rainforest loop

Hidden Trail

Quieter cousin to the Hoh. Six of the country's largest conifer species along one trail.

Iron Goat Trail

Ruin

Abandoned Great Northern railway grade with tunnels and snow sheds slowly returning to forest.
