Attend the 15th Annual Big Nasty Hillclimb

September 6th-9th, 2018

September will be here before you know it, and you know what that means.....the 15th annual Big Nasty Hillclimb 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 it is ALWAYS held two weeks after Labor Day Weekend, which usually means PERFECT weather.  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 music that we've ever offered, sample our large and varied food court, check out our full service bar, turn the kids loose in our play area with an inflatable waterslide, 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), and marvel at our famous Saturday night fireworks show. The Nasty is the final round of the 2017 North American Hillclimbers Association Pro Hillclimb Series which gives you the chance to see the best hillclimbers on earth compete for a $20,000 guaranteed pro purse, topped of by the infamous and wild, Sunday afternoon King-of-the-Hill finale where 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.

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.

Important Notice:

All campfires MUST be contained in a metal or ceramic container such as a firebox or barbecue.  There cannot be any fires of any kind directly on the ground for any reason.

Dogs are welcome at the Big Nasty, but ONLY service dogs can come into the fenced-in spectator area.  Other dogs must be leashed at all times.  Please do NOT bring pit bulls to the event.  Personally we LOVE well-behaved pits, but Payette County has a pit bull ordinance that makes it illegal to have or transport pits in the county.  Every other breed is welcomed as long as our guidelines are followed.
