Imagine if chlorophyll was not present in plants or trees?  Chlorophyll is the key to photosynthesis, the mechanism for plants to convert sunlight into food in the form of glucose.

If somehow plants could achieve photosynthesis differently, trees especially  would look like autumn throughout much of the year because its the chlorophyll cells that give plants their predominately green color.

Without any chlorophyll, gold, red and yellow would be the normal colors we see year round.  It would be wild to see the beautiful colors we enjoy during autumn all the time.  Although a lawn of orange grass would be weird, admittedly?

That bit of fantasy aside, it's time to start planning a trip to enjoy the beautiful seasonal color in Washington state

Here is a collection of what the Evergreen State offers for great fall foliage viewing by car, hiking or bicycling.


Maple Pass Loop, North Cascades

7.2 miles | 2,000 feet elevation gain

Sullivan Lakeshore, Colville National Forest

8.2 miles | 250 feet elevation gain

This popular out and back trail from Sullivan Creek Campground to Noisy Creek Campground features Western larches, aspens, hemlocks, and birch trees.  Along the way, the gentle elevation gain passes by beaches with nice mountain views. There is a $5 day use fee charged at either campground.

The Yakima Greenway Trail is paved for the 21 mile route from Union Gap, west to Naches.  The path travels along the Yakima and Naches Rivers. This ride is perfect for a family trek.

Stevens Pass Greenway to Leavenworth

104 miles

From Everett, follow US2 through the Cascades. The highway summits  Stevens Pass and descends through scenic Tumwater Canyon along the Wenatchee River towards Leavenworth.  The fall display includes vine maples, scarlet dogwoods, and yellow and orange cottonwoods.  Its distracting so keep your eyes on the road through the curves. The bavarian village of Leavenworth hosts the annual Autumn Leaf Festival in September and an Oktoberfest in October, of course!

Sequim to the Hoh Rain Forest Visitor Center, Olympic Peninsula

105 miles

The Olympic Peninsula is not just evergreens and rainforests.  During autumn, there is a brilliant display of oranges, reds and yellows along with evergreen forests. The scenic trip begins in Sequim on Highway 101 and through Port Angeles towards the Hoh Rain Forest and visitor center.  There are a series of short hikes that begin at the visitor center if you are interested that are less crowded on weekdays.

Chuckanut Drive Scenic Byway

21 miles

Chuckanut Drive from Burlington to Bellingham is one of the most scenic drives in Washington anytime of year.  You'll pass through Skagit Valley farmland and along the cliffs of the Chuckanut Mountains.  If you only have a short amount of time to spot fall color, the maples, vine maples, and alders are packed along the Chuckanut Drive highway with the bonus views of Samish Bay and the San Juan Islands offshore. But you might want to take your time and enjoy the many stops along the way including Larrabee State Park.

Columbia River Gorge Highway 14: Washougal to White Salmon

50 miles

The incredible Columbia River Gorge offers glimpses of waterfalls and the basalt cliffs towering above. The autumnal display just adds to the magnificence. Plan a picnic at  Beacon Rock State Park.  If you are up to it, the 52-switchback trail up Beacon Rock itself takes about an hour to climb but the payoff is more stunning views of the fall color across the Gorge.
