Autumn is a beautiful season for hiking in the Pacific Northwest, and Washington is full of breathtaking trails that show off its fall foliage. But while many head to the Cascades or Mount Rainier National Park to hike, one of the best fall trails is located in Eastern Washington… way east, as a matter of fact. If you’ve never explored Sullivan Lake, make this the autumn you do.

Sullivan Lake is located near Metaline Falls in the Colville National Forest.
