Insider Guide: Why Fall in Washington State is the Best Time to Explore

If the universe let me press pause one season, it would be during fall in Washington State.

When foliage turns warm-toned. When chilly air ushers in sweater season. When the moody Pacific Northwest vibes are in full swing. (If you are a fellow Twilight fan, you know what I mean!)

Welcome to the ultimate guide to enjoying the Evergreen State during the most beautiful time of the year!

What to Expect During Fall in Washington State

Like every season, autumn has its pros and cons. For first timers, it’s important that to be as prepared as possible.

While technically fall begins in late September, the changing of the leaves varies year to year — and is really on Mother Nature’s schedule more than our calendar.

And, it starts to feel like fall earlier the higher elevation you go. So, for example, it is common to see fall colors popping up and low temps dropping down in early September. In comparison, it usually isn’t until October and November that trees in cities like Tacoma or Seattle peak.

Because of this, I like to think of the start of the fall season as September 1st. Typically, the season winds down by mid-November.

What to Pack on Autumn Adventures

Often times (especially in September), it will feel like sweater weather in the mornings and evenings. But, expect mid-day to be too warm for those layers!

So, most outdoor adventures will require a mix of warmer and colder weather clothing.

Early Fall Outerwear

More than anything else, I find that a lightweight waterproof, wind-breaking layer is helpful. This way, you can stay warm enough on mountain hikes and keep dry when rain showers pass through.

Fall Footwear

As you may expect, rain that falls during this time of year often does not completely dry out on the ground. So, this means hiking trails may be muddy (even when there hasn’t been rain that day).

For this reason I always recommend wearing waterproof hiking shoes or boots. They come in handy for stream crossings too!

Autumn Accessories

Lastly, if you plan on spending a considerate amount of time in the mountains then you will need more than a jacket to stay warm.

Think winter: beanie, gloves, wool socks, gaiters & hand warmers will be your best friend!

Late Fall Outerwear

As a general rule of thumb, when October and November roll around it will be wise to prepare for winter conditions.

This is something I learned on my first larch hike in the North Cascades back in 2022. Luckily, we opted for down puffer jackets instead of just rain jackets. Not only was the wind chill significant, but it started snowing on our way back!

In these conditions, you have two options:

Parka Jackets

Long waterproof jackets that keep you warm AND dry. The main downside of these is that they are pretty heavy, so if you are hiking (particularly uphill) you may actually get too warm.

However, these are great for activities in which you won’t be super active — like scenic drives or picnicking.

Rain Jackets Layered Over Puffers

This is my go-to! Wearing a puffer jacket or vest underneath a waterproof shell is the most versatile, flexible way to stay warm and dry. For me, I tend to run warm so a puffer vest is usually what I reach for.

How to Have a Bucket List- Worthy Fall in Washington State

Go for a Day Hike

Without a doubt, some of my best memories of fall in Washington State are made hiking! If possible (passes are open and clear of winter conditions), heading to the mountains is your best bet.

Huckleberry bushes, vine maple shrubs, and larch trees deliver so much color to landscapes. At times, I hardly believed my eyes.

Here are a few of my favorite day hikes:

  • Naches Peak Loop at Mount Rainier National Park- 3.5 miles & 700′ elevation gain (easy-moderate)
  • Skyline Loop Trail at Mount Rainier National Park- 5.6 miles & 1,700′ elevation gain (moderate)
  • Cutthroat Pass at North Cascades National Park- 11.9 miles & 2,500′ elevaiton gain (hard)

Take a Scenic Drive

For a fun activity with the whole family (or maybe when it’s just too cold outside) is to take a scenic drive. Again, I recommend setting your sights on the mountains.

This way, you’ll get to see beautiful fall foliage, picturesque roadside stops, and charming small towns.

Here is a handful of gorgeous scenic drives:

  • Chuckanut Drive (near Bellingham)
  • Mt. Baker Highway to Artist Point
  • Stevens Canyon Road (Mount Rainier National Park)
  • Highway 2 up to Stevens Pass

Feel Like a Kid Again at the Washington State Fair

An early fall tradition that I have been enjoying since I was 1 year old is the biggest fair in the Pacific Northwest: The Washington State Fair! (Formerly known as the Puyallup Fair)

Starting right after Labor Day, this month-long celebration includes rides, games, animals, agriculture, arts, concerts, fireworks, and fair food!

Typically, you can count on the fair to be open in early and mid-September. However, they are closed Tuesdays.

Getaway to a Cozy Cabin

If you’re anything like me and fall is your favorite time to travel, then a relaxing getaway to a cabin deserves a spot on your agenda!

Luckily, in Washington there is no shortage of A-frame cabins, unique treehouses, and otherwise noteworthy vacation rentals.

If you are looking to splurge or celebrate a romantic occasion, then my top pick would be Treehouse Point. It’s conveniently close to Seattle, and is hands-down unlike anywhere you’ve been before.

Snoqualmie Falls is an amazing fall waterfall

Chase Powerful Waterfalls

Last but not least, another reason to adore fall in Washington State is that our waterfalls are full! In case you didn’t know, many of them dry up by late August (due to being fed by rain and snowmelt).

But with more rain comes more water gushing over waterfalls!

One that I visit time and time again during this season is Snoqualmie Falls. While it isn’t exactly a hidden gem, this season tends to be quieter than summer. Plus, the foliage is stunning!

Bestie Tip: Make a reservation at the Salish Lodge & Spa’s restaruant for brunch after hiking down to the base of the falls.
