Welcome to the official page for the Custer County Fair and Achievement Days! Our hometown fair has a long history in the community. We have events for people of all ages from 4-H'ers to those who are just kids at heart. There are many opportunities to get involved whether you submit a prize winning plant from your garden, enjoy BBQ sandwiches or you are a proud owner of a ranch horse and more! Part of the mission of the fair and fair board is to provide activities that promote positive community and family relations through safe and healthy community functions and events. Many of the events are free to the public and entry fees remain low. We have food, animals and vendors for you to enjoy. We would like to invite you to explore our website and join us this year as the locals come together.
