Come explore the Castillo de San Marcos for free. The National Park Service is waiving entrance fees so all can experience history come alive. Through out the weekend parks’ staff and volunteers will present historic weapon firing demonstrations and living history programs about the culture of an eighteenth century Spanish garrison. The weapons demonstrations are offered at 10:30, 11:30, 1:30, 2:30, and 3:30 on both days of the weekends, weather and staffing permitting. Ranger-led programs are presented every hour daily.
