Ready to hit the trails with your running shoes in Washington State? You've come to the right place. This guide breaks down some prime spots for trail running, with the latest intel to help you plan your next outing. Whether you're looking for challenging climbs or scenic routes, Washington's diverse landscapes offer year-round opportunities.
Snoqualmie Region
This region is a trail runner's paradise, easily accessible from the Seattle metropolitan area and offering a wide range of terrain.
-
Granite Mountain: Known for its rewarding summit views, Granite Mountain presents a solid climb. As of a March 2nd report, the trail was becoming snow-covered around 4000ft, requiring microspikes for traction. Even with snow present, as noted in a February 6th report, the higher elevations can hold snow longer than they appear from the highway.
-
Granite Creek Trail to Granite Lakes: This option offers a beautiful journey to alpine lakes. A March 22nd report indicated the trail to the bridge crossing the Granite River was largely snow-free, with a few easy-to-step-over blowdowns. The same report mentioned stream crossings as a notable obstacle, so be prepared for wet feet.
-
Mount Si: A classic PNW workout, Mount Si delivers a steep ascent with a popular summit. Recent reports from March 21st suggest a return to spring-like conditions, though patches of snow lingered, especially higher up. Even as of March 14th, significant fluffy snow was present from the parking lot onwards, highlighting the need for appropriate footwear.
-
Franklin Falls - Winter: While named for winter, this trail can offer a unique running experience as snow recedes. A March 9th report indicated that the road leading to the falls was snow-free, though a Sno-Park permit was required for parking by the closed road. Snow was minimal on the trails themselves, except for a few spots.
-
Rattlesnake Mountain - Grand Prospect: For a challenging run with expansive views, Grand Prospect is a good choice. A March 15th report detailed a trail that was almost completely snow-covered to the summit, with icy conditions at lower elevations, packed snow in the middle, and soft, deep snow near the top. A group reported turning back on March 14th due to deep snow about a mile from the summit.
-
Middle Fork Snoqualmie River: This trail offers a more mellow, yet potentially very wet, running experience along the river. Reports from March 8th describe the trail as extremely muddy, with sections turning into streams, making it challenging to navigate without getting wet. Be ready for soggy conditions if you head out.
-
Mount Washington: Another peak offering great views and a solid workout. A March 21st report mentioned the access road was in good condition, passable by most vehicles. Snow starts about halfway up, according to a February 26th report, so be prepared for winter conditions as you gain elevation.
-
Annette Lake: This alpine lake destination provides a scenic run. A February 28th report noted the trail was heavily snow-covered but still hikeable with trail runners and a pole; microspikes would have been beneficial. Access to the trailhead road can be rough, with potholes, and potential flooding across the bridge, as noted in a November 2025 report.
Olympic Peninsula
The Olympic Peninsula offers a different kind of trail running, often with coastal influences and dramatic mountainous backdrops.
- Mount Ellinor: This peak provides a steep and rewarding climb with views of the Puget Sound. Conditions are described as unusual for this time of year as of a March 22nd report, with steep, hard snow sections still requiring mountaineering gear, yet melted enough in places for glissading. A February 28th report details a successful C2C (car-to-car) ascent from the lower trailhead, taking about 3-3.5 hours.
North Cascades
The North Cascades are renowned for their rugged beauty and demanding terrain, perfect for experienced trail runners.
-
Mount Pilchuck: This iconic peak offers challenging terrain and panoramic views. The latest reports are from September 2025, indicating good road conditions to the trailhead and pleasant weather. Be aware that smoke from regional fires can be a factor, as noted in a September 23rd report.
-
Heather Lake: A beautiful lake destination with a classic Cascades feel. A March 22nd report noted the trail was mostly dry for the first 0.75 miles, then became much wetter with streams running down the trail and slippery conditions developing. A January 25th report from last year mentioned icy patches on the Mountain Loop Highway, even in the afternoon, so check road conditions.
-
Heather - Maple Pass Loop: This highly popular loop is known for its incredible autumn colors and alpine scenery. The most recent reports are from September 2025, indicating pleasant weather and ample roadside parking due to a closed parking lot for repairs. As of October 2024, crowds were minimal after the peak larch season.
Planning Tips for Washington Trail Running
- Check Mountain Loop Highway Status: For trails in the North Cascades like Mount Pilchuck and Heather Lake, verify the status of the Mountain Loop Highway, as it can be subject to closures and conditions can change rapidly.
- Traction is Key: Depending on the season and elevation, be prepared for snow, ice, and mud. Microspikes, gaiters, and waterproof shoes are often essential for early spring and late fall runs.
- Permits and Passes: Many trailheads require specific passes, such as a Northwest Forest Pass, Discover Pass, or a Sno-Park permit for winter access. Research the requirements for your chosen trail in advance.
- Report Conditions Regularly: Contribute your own findings! Sharing recent trail conditions helps fellow runners stay informed and plan safely.
