Washington State offers a year-round paradise for trail runners, from the lush temperate rainforests of the Olympic Peninsula to the rugged peaks of the Cascades. Whether you're chasing alpine lakes, summit views, or peaceful riverside paths, this guide will point you to some of the best terrain for your next run.
Snoqualmie Region
This region, easily accessible from Seattle, boasts a dense network of trails that cater to all levels of trail runners, from quick singletrack loops to challenging mountain ascents.
- Granite Creek Trail to Granite Lakes: A fantastic option for a solid workout with rewarding lake destinations. Recent reports from November 8th indicate that while debris from a windstorm was present, Middle Fork Road was clear and passable for all vehicles. Stream crossings were reported as easy with normal water levels as of November 7th.
- Granite Mountain: For a serious test of endurance, Granite Mountain delivers significant elevation gain over a moderate distance. An October 24th report mentioned overcoming initial hesitations about switchbacks and highway noise, finding the climb challenging yet rewarding. The trail covers approximately 8.74 miles with over 3,700 feet of elevation gain, as noted on October 23rd.
- Middle Fork Snoqualmie River: This section of the Middle Fork offers a more serene running experience along the river. A late October 31st report highlighted a favorite lunch spot about 4 miles in, accessible via a short path to the river rocks, ideal for late summer through fall. Another report from October 27th mentioned abundant mud and mushrooms, with solitude found until nearing Dingford Bridge.
- Snow Lake: A popular destination, Snow Lake offers a beautiful alpine run, though conditions can change rapidly with the season. As of November 4th, there was some snow at the lake, and the trail was described as mostly good with mud and snow, recommending microspikes. An earlier November 1st report indicated icy conditions and the start of microspike season, with parking lots filling early.
- Melakwa Lake: This trail leads to a picturesque alpine lake, offering a good challenge. A September 26th report, exploring the area beyond Franklin Falls, described it as a harder hike. Comments from September 18th praised the new parking lot at the Denny Creek Trailhead, noting ample space.
- Ira Spring Trail - Mason Lake: Known for its steep initial climb, this trail rewards runners with access to beautiful Mason Lake and, on clear days, views of Mount Rainier. An October 14th report described the ascent as a "butt buster and heart thumper" before leveling out towards the lake. Fall colors were beginning to pop in early October reports.
- Mount Si: A classic and accessible climb, Mount Si is a local favorite for a quick, steep workout. A report from October 2nd noted surprisingly empty parking lots on a fair-weather Friday morning, indicating good opportunities for solitude. It's a popular spot for fitness assessment, as noted in a July 1st report.
- Talapus and Olallie Lakes: Running between these two alpine lakes provides a well-rounded mountain experience. As of October 1st, the Olallie Lake trailhead was closed, but accessing it via the Pratt Lake trailhead was a viable option, adding extra elevation gain. A September 11th report detailed a one-way hike totaling about 13.5 miles with around 3000 feet of gain.
- Mount Teneriffe: This trail offers a steady climb through forested terrain, with options to extend the run. An October 31st report found the ascent a bit underwhelming with only one lookout, but noted the fall colors added visual interest. For those seeking a longer outing, it can be combined with other trail systems.
- Teneriffe Falls: While the falls themselves can be a destination, the trail offers a good climb. A report from August 31st noted the falls were dry, suggesting conditions can vary significantly. Another August 2nd report reiterated that Teneriffe Falls were dry, though this could change with recent precipitation.
Mount Rainier Area
The grandeur of Mount Rainier provides an awe-inspiring backdrop for trail running, though higher elevation trails are more seasonal.
- Skyline Trail Loop: This iconic loop offers unparalleled views of Mount Rainier and surrounding meadows. Reports from mid-October (October 20th and 19th) indicate pleasant fall weather, with parking lots at Paradise being busy, especially on weekends, even in the shoulder season. Expect crisp air and potentially strong sunlight.
Olympic Peninsula
Home to the temperate rainforest, the Olympic Peninsula offers a distinct running experience with lush vegetation and coastal influences.
- Mount Ellinor: This popular climb offers panoramic views of the Puget Sound and Olympic Mountains. A report from October 15th described the trail as being in "perfect shape" and surprisingly busy even on a weekday evening, with runners passing people still heading up. An earlier October 10th report noted a wet and cold day but still a wonderful experience, with potential for summit views later in the day.
Planning Tips
- Check Road Conditions: Especially in the Snoqualmie and Olympic regions, many access roads are unpaved and can be affected by weather. Recent reports often mention road status.
- Seasonal Gear: From November through April, expect ice and snow at higher elevations. Microspikes or traction devices are often recommended, as noted in recent Snow Lake reports.
- Parking Availability: Popular trails, particularly near urban centers like Seattle, can see parking lots fill up very early, even on weekdays during peak seasons. Consider weekday runs or very early starts.
- Variable Weather: Mountain weather is notoriously unpredictable. Be prepared for rapid changes in temperature, wind, and precipitation, even on otherwise clear days.
