The park is open from 8 a.m. to sundown daily. The fort and visitors center is open from 9 a.m. to 5 p.m. daily. It was based on a sketch by Jacques le Moyne, one of the original settlers in Fort Caroline, which was established by the French in 1564 and sacked by the Spanish in 1565. The site also includes a gift shop and museum and a nature walk. Nearby is the Ribault Monument, which offers a spectacular view of the St. Johns River, and the Theodore Roosevelt Area, which offers trails for hiking and biking.
Admission is free.
However, the number of tours can vary, so it is a good idea to call ahead. Children under 16 are free if accompanied by an adult. A small museum features an eight-minute film about the fort and the area's history. To get to the fort itself, it is necessary to take a ferry, since the fort is on Rattlesnake Island. A park ranger accompanies each ferry and gives a short tour.
