Blackwater River State Park was established in 1967 and opened in 1968 with 360 acres. In 1981 an additional 230 acres were acquired from the Division of Forestry.
Blackwater River State Park has one recorded archaeological site–an unnamed stone scatter, which may be as old as 10,000 years or as recent as a few hundred years old. Since rivers have been major transportation corridors in Florida for more than 10,000 years, it is probable that human activity existed here long ago.
The park and adjoining Blackwater River State Forest are known for their historic trams, sawmills and timber industry, especially near Milton. It is interesting to note the geographical distribution of mills along the streams and watersheds.
When mills were at peak operation, everyone made trips to mills. The earliest roads led to mills and as the community grew, commercial ventures such as the blacksmith shop, livery and general store would spring up nearby.
Atlantic white cedars line the river. In 1982, one of the park’s cedars was designated Florida Champion, the largest of its species. The park was also designated a Registered State Natural Feature in 1980 for its “exceptional value in illustrating the natural history of Florida.”
