Using a national farm survey, this study estimates a logit model to identify factors affecting U.S. farmers' participation in agritourism. Of the dummy variables, public access to the farm for recreation has the greatest positive impact, followed by farms near central cities, farms in Rocky Mountain and Southern Plains regions, farmers with college education, farmers paying for farm advice, farms organized as partnerships/corporations, farms enrolled in conservation programs, and farmers with access to the internet. Continuous variables affecting participation include acres of owned land, percent of land unsuitable for crops, operator age, and distance to cities. Targeting farms and farmers with these traits can increase the success of agritourism promotion efforts.
