Northwest Nitro Nationals (NWNN) is proud to announce the 5th Annual North American Hillclimbers Association (NAHA) Pro Hillclimb Series event held in Sunnyside, WA May 8th-10th, 2015.  The NWNN / NAHA Pro Hillclimb Series draws the top pro hillclimb athletes in the world to our venue!   Round 2 (out of 6) of the NAHA pro events nationwide this year.

In 2014 the NAHA voted Northwest Nitro Nationals "Venue of the Year!" Our ever evolving hill design, expansive parking, camping and vending area allows for continued growth - and of course, we thank you for your support!

We're also round 1 of the Northwest Hillclimb Series for our amateur and semi-pro classes!
