Top Pet Friendly Hikes Near Seattle

The Seattle-area offers some seriously spectacular dog friendly hiking, without having to drive more than ninety minutes (traffic permitting, of course!). And the Washington Trails Association has one of the best hiking websites and apps I’ve ever used, allowing you to save favorite hikes and access hiking information even when you’re offline.

Several Facebook groups also provide sage advice about current trail conditions and other information. For insider tips on specific hikes or hiking in general check out Washington Hikers and Climbers, PNW Outdoor Women Group, or Canines in the Cascades.

It would be easy to gather a list of 30 excellent dog friendly hiking locations near Seattle. But instead I’m sharing my all-time favorites for year-round adventures.

Cougar Mountain

Located in the Issaquah Alps, the 3,100-acre Cougar Mountain park has a network of 36 miles of dog friendly hiking trails, just 15 miles from downtown Seattle. This is a trail runner’s paradise and urban hiker’s dream!

Originally serving as a food acquisition area for Native American tribes who would forage wild roots, plants, and berries, as well as hunt game, this became a mining area after European settlers arrived. And in the 20th century logging operations took over.

The US military utilized the forest for two active missile sites during the Cold War in order to protect the Puget Sound from potential airstrikes.

Finally, in the late 1960s, King County took control of the land and developed it into the park that is there today. Several artifacts from the mining days still appear on various trails, including exhibits, a concrete dam, a covered mine shaft, and a mine cart.

Cougar Mountain is full of streams, waterfalls, single track trails, and bashful wildlife. The highest peak in the park is Wilderness Peak at 1,595 feet, and the trails vary in length and difficulty from wide easy paths to serpentine uphill challenges.

Information on Cougar Mountain is easy to find with a detailed Wikipedia entry that includes descriptions of all the trails, their lengths, and where to access them. And King County provides an online trail map, as well as signs and printed maps at the trail heads.

Annette Lake

If you’re into waterfalls, turquoise rivers, alpine lakes, and mountain views, then head out to Annette Lake for the day or plan an overnight trip!

Depending on the year, the snow can remain well into spring. I did this hike in late May a few years ago and crossing the snowfields was a bit unnerving without spikes and poles. And the lake was still almost completely covered in snow and ice!

The trail is well-maintained and not terribly demanding, gaining 1,800 feet in the 7.5 miles roundtrip. A NW Forest Pass is required, so be sure to pick one up before heading out.

One of the highlights of this hike is not far from the parking lot — the rushing turquoise waters of Humpback Creek. Before crossing the bridge, take advantage of the nice photo opp on the rocks along the water. And take a moment to admire the cascading falls tumbling downstream.

After crossing a few small streams, you’ll reach several steep slopes with views of Granite Mountain and Humpback Mountain. Once the snow starts to recede, watch for wildflowers like trillium.

Once you pass through the slopes, Annette Lake is not far beyond. There are several spots to enjoy a picnic lunch, or even a swim if you’re up for a cold shock!


Franklin Falls

Franklin Falls is a nice, easy hike just off 1-90 that’s perfect for beginners and those hiking with kids. The two-mile leisurely trail ends at a 135-foot waterfall that cascades between the highway viaducts. A NW Forest Pass is required to park in the lots and hike the trails.

A short, steep path with a handrail guides hikers right up to the waterfalls. The spray is heavy and rocks can be quite slippery, so take care. And bring a wipe for your camera lens, or all your photos will be cloudy!

For a special treat, visit Franklin Falls during the winter months when the falls are frozen. You’ll have to research the best trail access when you go because the snow can force parking lot and/or trail detours. The above-mentioned Facebook groups can be of great assistance.

Bring spikes for traction and plenty of warm clothes – it gets very chilly by the falls. The steep slope leading to the bottom of the falls is icy during the winter, so go slowly and take small steps while hanging onto the wire rail.

This is a popular hike, so arrive early, even in the winter. Or, better yet, head there on a weekday.


Cherry Creek Falls

Just a short drive outside of the quaint town of Duvall, Cherry Creek Falls is a sweet little gem with mostly local traffic. This easy, five-mile hike was originally the site of a logging camp and is accessible any time of the year.

With the large network of pet friendly trails, it’s also a great destination for trail runners looking to go for longer distances with their furry companions.

The route follows a well-maintained path with several river crossings. Some have sturdy bridges, while others consist of a simple wide log stretched across the span.

During the winter and spring, the creek is often rushing and water levels can be high, making the crossings a bit sketchy. Dogs seems to have far more bravery and balance than their humans, but be careful with your pups if the water poses a hazard.


The trail gradually descends to the 25-foot waterfalls and passes an old rusted car that makes a good photo spot. The sandy shore of the waterfall pool is spacious with plenty of good logs to sit and enjoy the view or eat a snack.

Afterward, continue up the path above the waterfalls to complete a semi-loop. Or simply turn around and head back the way you came.

This trail can be muddy during the rainy months, so bring waterproof shoes. Also note that there is no official parking lot for the hike, as the first half mile is located on a courtesy easement on private property. There is a shoulder just before the trail head where you can leave the car. Don’t park where signs indicate “private road” or you will be ticketed.

Ira Spring Trail At Mason Lake

Named for one of Washington’s most important trail advocates, Ira Spring was a photographer and conservationist whose namesake trail befits his legacy. Wildflower fanatics will love Ira Spring Trail at Mason Lake during peak bloom.

The elevation gain on this trail is fairly significant — 2,420 feet in just over three miles. But the rocky ridges offer fantastic views of Mt. Rainier to take your mind off the climb. After summiting the high point of the hike at 4,320 feet, the trail descends into Mason Lake.

There is ample space to find a shady spot for a picnic. Or perch atop one of the massive boulders to soak in the sunshine. Dogs will enjoy playing fetch or cooling off in the turquoise lake.

Camping is also possible at the lake, complete with designated camping areas and a backcountry loo. Before your visit, pick up a NW Forest Pass, which is required for parking and utilizing the trails.

Heather Lake

Accessible most any time of year, Heather Lake is a hike for all seasons. Winter months mean fewer crowds – just be sure to use your micro spikes! And fall brings brilliant colors, thanks to all the berry bushes.

This hike is great for any level of hiker looking for a moderate challenge. The climb begins as soon as you hit the trail and winds through old and new-growth forests. The vibrant shades of green are noteworthy, with evergreens, moss, and ferns spreading in all directions.

After a bit of climbing, you’ll reach a boardwalk that leads to the lake. Bring waterproof shoes, as there are a few water crossings, including a small waterfall that makes for a nice photo stop.

Find a good picnic spot, or continue all the way around the lake to absorb the full perspective. In the winter, the boardwalk can be slippery, so be cautious.

Grab your NW Forest Pass and arrive early to beat the crowds, especially on weekends. Arriving at the parking lot before nine will give you a better chance of having the lake to yourself. In fact, pack a hammock to enjoy a few moments of hang time before everyone arrives!

I hope this post give you some new places to explore when hiking with your dog near Seattle! Perhaps we’ll see you out on the trails.
