Unique among National Parks, the Castillo de San Marcos embodies nearly 450 years of history and culture that can not be fully experienced in a single visit. A little planning ahead will help make the most of your time with us.

We encourage you to explore our website and discover those areas and activities that interest you the most. The site provides both basic information and background studies that can help you plan a successful visit to the Castillo.

When planning your visit, please keep in mind the average visitor spends between one and two hours at the Park.
