Cycling, Walking, Running

Originally constructed in 1917, the Old Lewiston Grade (Spiral Highway) has generated many stories attributed to its many curves and switchbacks. Replaced by the current highway more than 30 years ago, the 8-mile Spiral Highway has become famous for the challenge it presents to participants of the “I Made the Grade” annual bicycle race. The race climbs from the river’s edge to the top of the valley, and attracts riders from throughout the region. Mountain biking enthusiasts can enjoy miles of trails in Hells Gate State Park. Casual bicyclists, walkers and runners have free access to more than 25 miles of paved pathways on the Clearwater and Snake River Recreation Trail. The Lewis-Clark Valley’s mild climate allows for use of the bike paths year round. The annual Seaport River Run, held every April, allows serious competitors and amateur runners a challenging course covering both sides of the Snake River.
