Trinity County Fair Raceway

The best dirt track race action around! 
With a lot of volunteered time from racers, family, friends and community members and even more elbow grease... Mountain Valley Raceway was born! Located at the Trinity County Fairgrounds in Hayfork, California, the track has been a true labor of love. 

The track offers fun for the amateur and veteran driver alike as racers drive hobby stocks, modifieds, hornets, sprint cars and more. ​

Gates open at 6PM, races start at 7PM.
