September 18th - 20th, 2020

September will be here before you know it, and you know what that means.....the 18th annual Big Nasty Hillclimb & Country Music Festival is coming up. The Big Nasty is the nation's largest motorcycle Hillclimb, with up to 13,000 spectators and 900 entries, and is also Idaho's largest motorcycle event and we have returned to our traditional date of TWO weeks after Labor Day Weekend. The Nasty offers everyone in the family fun things to do:

  • Watch violent and insanely loud 200-horsepower bikes try to climb a cliff
  • Enjoy the best live country music that we've ever offered with nine bands on three evenings
  • Turn your kids loose at our inflatable bounce house and razor trike races
  • Enjoy our varied and delicious food court
  • Check out our full service bar
  • Take a scenic helicopter ride

Bring your tent or RV and enjoy camping in the adjoining pastures (we sell nearly 1,000 camping passes every year)! The Nasty is the final two rounds of the 2019 North American Hillclimbers Association Pro Hillclimb Series. This gives you the chance to see the best hillclimbers on earth compete for a $20,000 guaranteed pro purse on Saturday, a second large pro purse on Sunday and finally the infamous and wild Sunday afternoon King-of-the-Hill finale. Come witness the best of the best vie for even more bonus cash as they throw themselves at a sheer, 15-foot high cliff about half the way up the hill.

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.

Come Witness Idaho's Coolest Event & Country Music Festival!

The hill at New Plymouth's Big Nasty Hillclimb is more than 450 feet tall and with an average slope of 62 degrees, it is common for most bikes to not make it over, often flipping over trying to do so. You'll get to see some of the most exotic competition bikes in the world attempt to race up these near-vertical faces. Pros show up on customized nitro-fueled or nitrous-powered bikes with lengthened swingarms and steel-studded or chained rear tires. We guarantee there will be thrills and spills on this hill!

You can buy your tickets for admission at the front entrance gate when you arrive at the event venue. Tickets are good for the entire weekend, so you can come and go as you please. Contact Big Nasty Hillclimb with any questions pertaining to the festival.
