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.

The Sullivan Lake Trail is over eight miles in length (round trip), but it’s not extraordinarily difficult.

Andrea Hoffman / alltrails.com Quite a bit of the trail parallels the shore of the lake, and every bit of it is beautiful.

Begin your hike at the East Sullivan Campground at the north end of the lake

Eventually, you’ll get your first glimpse of Sullivan Lake. The trail takes you on a quick descent until you’re right at the shoreline.

The aspen and Western larch trees are what makes this area so stunning in the autumn.

Morgan Montanez / alltrails.com Western larch is the only species of larch that’s spotted almost exclusively in the inland Northwest, and their needles turn lovely shades of yellow and gold.

As breathtaking as the scenery is, you’ll want to keep an eye out for wildlife on this trail.

Eventually, you’ll leave the lake and cross Noisy Creek before climbing another bluff, dropping down to Noisy Creek Campground.
