Gateway to the Meramec Valley

About this city

Also known as: Gateway to the Meramec Valley

Sullivan is a charming historic city situated on the border of Franklin and Crawford counties in east-central Missouri, positioned along the historic Route 66 corridor at the northern foothills of the Ozark Plateau. Officially incorporated in 1864 and growing rapidly as a copper mining and railroad transport hub, the city later earned national recognition as a vital roadside milestone for automotive travelers on the Mother Road. Today, Sullivan has beautifully transitioned from its early industrial roots into the absolute premier municipal gateway for underground karst eco-tourism, positioned immediately adjacent to Meramec Caverns. It pairs classic midwestern small-town nostalgia with river outdoor recreation.
