The fort was never fully completed, as construction was halted after the outbreak of the American Civil War.
During the Spanish-American War, the fort was briefly reactivated to serve as a base for troops.
The park contains one of the oldest maritime forests in Northeast Florida.
Local volunteers frequently host living history demonstrations featuring period-accurate reenactments.
The fort's design is a classic 'Third System' masonry fortification with an irregular pentagonal shape.
Fort Clinch State Park encompasses over 1,400 acres on the northern tip of Amelia Island, featuring a well-preserved 19th-century masonry fort. The park provides six miles of multi-use trails for hiking and cycling, traversing maritime hammocks and coastal dunes. Visitors can explore the fort’s bastions, guard rooms, and soldiers' barracks, which date back to the mid-1800s. The site offers two campgrounds with 62 campsites, situated among mature oak trees and near the Atlantic shoreline. Beach access is available along the park's eastern boundary, known for shark tooth hunting and shelling. The fort played a strategic role during the Civil War and the Spanish-American War. Saltwater fishing is permitted from the pier and along the designated shoreline areas. The park also serves as a trailhead for the Florida National Scenic Trail.

Bring a mesh strainer or sifter to increase your chances of finding shark teeth along the shoreline.
Carry insect repellent if planning to hike the inland trails, as mosquitoes are prevalent in the maritime forest.
Check the tide charts before visiting, as high tide can significantly reduce the amount of beach area available for walking.
Do not attempt to collect historical artifacts or metal detect within the fort walls, as this is strictly prohibited by state law.
Carry out all trash, stay on marked trails to protect dune vegetation, and do not touch or remove historical artifacts from the fort walls.
