Explore the Stone Walls of the Castillo De San Marcos National Monument

Visitors to the Castillo de San Marcos National Monument are encouraged to explore the fort at their leisure. The best view is up on the gundeck, which overlooks St. Augustine and the gorgeous Matanzas River. There are reenactors and rangers available throughout the site to speak with guests to answer questions, and give presentations about Castillo de San Marcos history. When you first arrive, ask around to find out when the next presentation is taking place. First-time visitors to the park should definitely make a point to watch the introductory video, shown every hour. It’s about a half-hour long and provides plenty of great Castillo de San Marcos facts.

Watch a Weapons Demonstration

If you’re staying at Agustin Inn through the weekend, walk over to the Castillo de San Marcos to watch the weapons demonstration. Every Friday, Saturday, and Sunday, reenactors explain and demonstrate the weapons of the Colonial era. This includes the firing of one of the historic cannons on site! The weapons demonstration is incredibly popular with visitors and locals alike and always draws a big crowd.

Spend the Day on St. George Street

Visitors generally spend about two hours at the Castillo de San Marcos National Monument. We suggest for visitors to get there around mid-morning when the weather is a little cooler and the fort is a little less crowded. This will also give you the rest of the afternoon to spend exploring St. Augustine. The Castillo de San Marcos is just a short walk from St. George Street, a pedestrian-only thoroughfare full of sites, shops, and delicious restaurants. If you’re in the mood for more history, visit the oldest schoolhouse in the U.S. If learning about the first Spanish settlers has gotten you in the mood for tapas, visit the Columbia Restaurant, which serves Spanish and Cuban cuisine. The best part? This is all still within walking distance of Agustin Inn!
