Attend the 15th Annual Big Nasty Hillclimb.

September 14-17, 2017

September will be here before you know it, and you know what that means.  It’s almost time for the annual Big Nasty Hillclimb, the nation’s largest motorcycle Hillclimb, which is ALWAYS held two weeks after Labor Day Weekend.  This festival style event is sanctioned by the North American Hillclimbers Association and it takes place over a four-day period.  You’ll have the chance to see the best hillclimbers on earth compete for a $20,000 purse and the prestigious and wild King-of-the-Hill Trophy.

Bring the entire family out to enjoy the spectacle or sign-up to be a volunteer.  If you like to climb hills on motorcycles or four-wheelers, throw your hat in the ring and sign up.  Call 208-573-4255 for information on how to compete and how to register.

It has several vertical ledges and slopes that can reach up to 62 degrees. You’ll get to see some of the most exotic competition bikes in the world attempt to race up these vertical surfaces. Bikers show up on customized nitro-fueled bikes with 1,200 cc engines and steel-studded tires. We guarantee there will be thrills and spills on this hill!
