Formerly an unincorporated community and census-designated place, it voted to incorporate in November 2020. As of the 2020 census, the population was 2,533. Holiday Island is located in the Ozark Mountains on Table Rock Lake, near Eureka Springs, Arkansas and approximately an hour's drive from Branson, Missouri, Fayetteville, Arkansas, and Bentonville, Arkansas. Community growth has been fueled by the expansion of corporate giants headquartered in Northwest Arkansas, namely Walmart, Tyson Foods, and J.B. Hunt; the entertainment attractions in Eureka Springs, AR and Branson, MO; the visitor traffic from the Crystal Bridges Museum of American Art, the Pea Ridge National Military Park, and the Roaring River State Park; and the influence of University of Arkansas, the state's largest university.
