Lewis River Trail – Dog-Friendly Hikes in Cougar, Washington

Lewis River Trail, nestled in Cougar, Washington, is a popular destination for dog owners looking for scenic, pet-friendly hikes. Renowned for its magical woodland atmosphere, abundant moss and ferns, and several breathtaking waterfalls, this trail offers a truly immersive experience for both humans and their four-legged companions. The soothing river, shady trails, and opportunities to cool off in the water make it one of the most sought-after dog-friendly hiking options in SW Washington.

This trail is mostly easy to moderate, accommodating even families with small children and dogs that enjoy long walks. Dogs are welcome, though they must remain on-leash as the park is not fully fenced and is adjacent to traffic and natural hazards. The area offers ample shaded spots and easy river access for cooling down during summer. However, there are no specific fenced or off-leash dog areas, and amenities such as water fountains, agility equipment, or waste stations are not present. Parking is available, but it can fill quickly on weekends, so an early arrival is recommended.

Magical trail with lots of moss and ferns. Three major waterfalls with some smaller ones along the way, and some great river spots where you can cool off on a hot day.

Beautiful hike is pretty easy. My 5 year old was able to do it. If you decide to take the trail up to curly falls be aware it has a pretty big drop off and the trail narrows quite a bit. If you are afraid of heights I recommend taking the road up to the falls.

October 20-24 is the best timing to have a happy hike at Lewis River for colored leaves. The view is stunning with mushrooms all along the trail ……

Just returned from a 3 day, 2 night backpacking trip on this trail. Not many people. Scattered spots to set up camp. Plenty of mosquitos near the water. Trail is in great shape. Fantastic time!

Really great hike for a hot day!

If you’re going for views/the hike I Would recommend first going to the Lower Falls. We ended our hike there and by the time we got there the view was obstructed by a lot of people enjoying the cool weather.

Lots of opportunities on the trail to get in the water and cool off mid hike. Trail itself is also mostly shaded.

Suggest arriving early. We arrived at trailhead @ about 8am and only a couple other cars there making for easy parking. By the time we left (around 2pm) all parking lots were full.

At time of review, NULL reservation + Forrest pass is required. Reservation was made on recreation.gov.
