For cyclists who appreciate a satisfying climb followed by a blissful downhill reward, Boise's Sidewinder Trail beckons. Contrary to some online reports, this 3-mile stretch is located right in the heart of Boise, Idaho—not hundreds of miles away. Whether it's your first singletrack or you're a seasoned biker, Sidewinder offers an array of experiences that promise a great day on the pedals.
Sidewinder starts with a playful bob and weave for the first half mile. But don't be fooled—this trail doesn't shy away from elevation. What sets this trail apart is the "roll of the trail": every uphill is preceded by a downhill, making the climbs a bit more manageable. For those keen on dirt bike routes, Sidewinder links up with the 8th Street Motorcycle Trail near the summit, which is notably loose and rocky.
Contrary to confusing information online, this trail starts right in Boise. Head toward Kelly Canyon Ski Resort and Heise Hot Springs, then turn right onto East Heise Road. Keep going until you spot a public parking area with Stinking Springs trailhead signs. Sidewinder starts across from this parking area, marked by a spring-loaded brown metal gate (not to be confused with dirt bike routes).
Two benches near the end of the trail offer excellent opportunities for a breather and to soak in the view. Alternatively, the trail can be done as a shuttle ride, starting from Y Junction and ending at Stinking Springs.
Sidewinder is a true Boise gem, ideal for cyclists looking for moderate challenges and scenic views. While not too technical, the trail requires riders to be on their game, offering a combination of flowy sections and uphill slogs. So if you're seeking an intermediate-level trail that's as engaging as it is rewarding, Sidewinder awaits. Enjoy the ride but remember, this is a busy trail—so keep an eye out for your fellow bikers.
