Crestview was built on the prosperity of its natural resources. Its easy accessibility allowed Crestview to continue to grow into a booming town of vast opportunity. The CSX, Inc. Railroad runs through Crestview, which brings business to the area. Parallel with this railroad, the Old Spanish Trail extends west from Jacksonville to El Paso, TX. This trail was one of the great truck lines of the country, and is rich in tradition and history of the Indian, French, Spanish and English settlers.
Crestview was officially incorporated in 1916. The name was chosen because of its location on the peak of a long woodland range between the Yellow and Shoal rivers, which flow almost parallel on the east and west side of the city. After the State Legislature formed Okaloosa County in 1915 from portions of the western Walton County and eastern Santa Rosa County, Crestview became the county seat in 1917 and remains so today.
