5 Can’t-Miss Mountain Bike Trails Around Seattle

Whether you’re a local Seattleite or a visitor making the trek to explore the Pacific Northwest’s verdant forests and velvety loam, the terrain surrounding the city is a mountain biker’s paradise. Often overlooked for its exceptional outdoor access, Seattle’s prime location—nestled between Puget Sound and the western slopes of the Cascade Mountains—blesses it with an unrivaled diversity of mountain biking trails.

From grueling climbs up tight switchbacks to lightning-fast, flowy descents lined with smooth berms and towering ferns, the riding here is nothing short of world-class. To uncover Seattle’s top mountain biking spots, we turned to the experts at evo Seattle—a beloved local bike shop stocked with premium gear from brands like Santa Cruz Bikes and Transition, plus helmets, accessories, hosted events, and professional bike repair services. Read on to discover the region’s most iconic trailheads:

A long-reigning crown jewel for mountain bikers in the Greater Seattle Area, Duthie Hill Bike Park sits on the Issaquah Plateau, roughly 25 minutes from downtown Seattle. Sprawling out from a central hub, the park features 16 miles of interconnected trails that balance speed and fun, with a total of 23 distinct routes catering to every skill level. Riders can choose from jump- and drop-laden flow trails, cross-country (XC) paths, or more technical sections equipped with wooden ladders and balance beams for those craving a challenge. If you’re new to mountain biking or just exploring Seattle’s trail scene, Duthie Hill is the perfect starting point.

One of the area’s newest trail systems, Raging River has quickly skyrocketed to local favorite status. While plans are in the works to link it to the nearby Tiger Mountain trail network (more on that below), Raging River already boasts an epic 45 miles of trail across 30 unique routes. Local riders swear by standout paths like Poppin’ Tops and Flow State, and the full loop is a must-try for anyone feeling ambitious. Just 35 minutes from Seattle via I-90 Exit 27, the Raging River trailhead delivers the ultimate one-two punch: a heart-pumping climb to get the blood flowing, followed by a thrilling, flowy descent that makes every pedal stroke worth it.

Tucked between Fall City and Snoqualmie Pass—35 minutes outside Seattle—the Tokul trail system is split into East and West sectors, each with its own dedicated trailhead (though both connect to the Snoqualmie Valley Trail for seamless access). The two areas offer distinctly different riding experiences: Tokul West leans into classic XC-style terrain from start to finish, while Tokul East caters to enduro enthusiasts with grueling logging road ascents paired with fast, flowy, and sometimes aggressively technical descents. Whether you’re chasing mileage or heart-pounding thrills, Tokul has a trail to match your vibe.

Tiger Mountain is widely hailed as the Pacific Northwest mountain biker’s mecca—and for good reason. Boasting a massive network of 49 trails spanning 46 miles, it offers something for every rider, from first-time beginners to seasoned pros. The climb to the summit via the Master Link trail is a manageable grind up moderately graded switchbacks, and the payoff is access to some of the area’s most white-knuckle descents (including the legendary Predator trail) plus timeless classics like Off The Grid and Fully Rigid. With endless looping combinations to mix and match, Tiger Mountain feels like a brand-new adventure every single time you hit the trails.

Located 45 minutes from Seattle, just past the popular Rattlesnake Ledge hiking trail, Olallie is a one-way trail that lets you customize your ride: pedal up as far as your legs can take you, then enjoy the ride back down. The golden rule here is simple—you get out what you put in. The higher you climb, the more rewarding the descent, which unfolds along perfectly sculpted, berm-lined singletrack that’s smooth as silk. Thanks to excellent natural drainage and regular maintenance from local work parties, Olallie is a stellar ride year-round, no matter the weather.
