Updated June 1, 2026

If you've ever tried to plan road cycling around Lake Marcel-Stillwater, you know how overwhelming the options can be. With so many roads winding through valleys and up hills, it's tough to tell which routes are genuinely worth your time and effort, and which are just filler. We get it – you want the good stuff, not the guesswork. That's where komoot comes in. Our community has ridden, mapped, and reviewed these routes, so we've curated a shortlist of the very best to save your legs and your planning time.

Road cycling around Lake Marcel-Stillwater is defined by its dynamic landscape. You'll find yourself in the foothills of the Cascades, where the terrain shifts from the broad, bucolic Snoqualmie Valley floor to the more demanding ascents around Stillwater Hill. This means you can choose between leisurely riverside spins and challenging climbs, all set against a backdrop of wooded hills, agricultural lands, and scenic river views.

If you only do one ride, make it the Lake Sammamish and Snoqualmie Valley Loop, a moderate 39.9 miles (64.3 km) that delivers expansive views and picturesque valley riding. For a slightly easier, classic valley experience, the Carnation Valley loop at 27.2 miles (43.8 km) is a local favorite, winding through scenic farmlands.

The Monroe/Duvall gravel loop offers a quintessential Pacific Northwest cycling experience, blending river valleys, green farmlands, and forested areas. You'll encounter diverse surfaces, from the packed gravel of the Snoqualmie Valley Trail winding alongside the Skykomish River to paved roads and some more rugged, chunkier gravel sections. Keep an eye out for views of the Cascade foothills as you navigate this dynamic landscape, passing by natural features like Lake Joy.

This difficult 46.4-mile (74.7 km) route includes 1824 feet (556 metres) of elevation gain, taking approximately 5 hours and 50 minutes to complete. It's best suited for cyclists with good fitness and a gravel bike equipped with tires wider than 32mm, ideally 35mm or more, to comfortably handle the varied terrain. Starting early is recommended, especially on weekends, to allow ample time and avoid busier periods on popular sections.

What makes this route stand out is its ability to combine various trails and roads, allowing for a customizable adventure through the region's scenic beauty. It offers a blend of expansive open spaces and wooded sections, providing a peaceful and ever-changing backdrop for your ride.

The Lake Sammamish and Snoqualmie Valley Loop offers a dynamic road cycling experience, blending serene lakefront paths with rustic rail-trail sections. You'll pedal past the shimmering waters of Lake Sammamish, enjoying continuous views and a peaceful atmosphere often separated from the road by greenery. The route then transitions to the Snoqualmie Valley Trail, where you'll find yourself amidst dense forests, with opportunities to spot swans on West Snoqualmie River Road and even Mount Rainier in the distance on a clear day.

This moderate 40.0-mile (64.3 km) ride, with 2055 feet (626 metres) of elevation gain, takes approximately 2 hours and 59 minutes. While much of it is paved, be aware that the Snoqualmie Valley Trail introduces crushed rock and hard-packed gravel, which can be tricky for road bikes. There's also a notable 2.5-mile on-road detour with stairs near the Reinig Bridge, so plan accordingly. Starting early on a clear day is recommended to make the most of the views and avoid busier times.

This loop is a testament to decades of planning, connecting you to a vast network of regional trails, including the Great American Rail-Trail. It's a fantastic way to explore the natural beauty of King County, passing through charming small towns like Carnation and offering a unique blend of urban and rural cycling. The varied terrain and scenic highlights make it a popular route for those seeking a diverse cycling adventure.

It depends on the time of year if the geese are migrating. We did not see geese in the field, but at least five different groups of dozens in each in the sky maneuvering around each other. It took one flock that seemed to know where they were going to head south and lead the others in the right direction.

The Redmond Ridge Trail is a regional trail that winds through the Redmond Ridge Trilogy neighborhood. The entirety of the path is paved and is popular with cyclists, runners and walkers. Along the way, a nice bridge and a few other spur trails split off into neighborhoods. The nature trails and the surrounding region are serene and quiet. This trail connects to the Tolt-Pipeline Trail, which serves as a significant connection between Duvall and the Sammamish River in Bothell.

Sikes Lake is a sizable reservoir just off the side of Northeast Carnation Farm Road. There is plenty of room off the side of the road to step off the bike and take in the view, or you can just enjoy the water as you fly by.
