Fort Matanzas: St. Augustine’s charming free fort

Fort Matanzas, 14 miles south of St. Augustine, is a fun, free, scenic stop

Fort Matanzas is not huge and grand like its older, bigger brother, the St. Augustine fort.

But the smaller fort 14 miles south of St. Augustine, has charms all its own, starting with the free boat ride you take to reach it.

Built in 1742, about 50 years after St. Augustine’s Castillo San Marcos fort, it is impressively historic, especially for everything-is-new-here Florida.

Fort Matanzas is located on a spectacular inlet with expansive views of water and marshland. Wildlife is abundant: Dolphin are frequently spotted in the water; wading birds fish along the shore, osprey fly overhead.

It’s right off a very scenic stretch of A1A.

Visitors reach the fort by a short ferry ride across the Matanzas River. Then you can climb a very narrow ladder to get to the top of the tower — people were smaller then!

The cost of visiting Fort Matanzas? It is all free.

As a national monument, Fort Matanzas is operated by the National Park Service.

Fort Matanzas ferry: As of June 2022, the ferry and fort are open Wednesday to Sunday with no ferry on Mondays and Tuesdays.

A tour takes an hour — that includes the boat trip to the fort, a talk by a park ranger and the trip back. Boats run at 9:30 a.m., 10:30 a.m., 11:30 a.m., 1:30 p.m., 2:30 p.m., and 3:30 p.m.

The visitor center offers a movie about the fort and near it is a pretty nature trail into a live oak forest. 

It’s also worth allowing more time to walk the short trail, explore the Fort Matanzas beach or have a picnic. Families with kids, in particular, should enjoy this outing.

Why did the Spanish build Fort Matanzas?

Fort Matanzas protects St. Augustine’s “back door” — the ocean inlet where the Matanzas River flows into the Atlantic. The fort is small: 50 feet on each side with a 30 foot tower.  When the Spanish occupied it, a force of seven men could man the tower and its five impressive cannons and stop incursions from the ocean. The informal ranger tour covers more Fort Matanzas history and the military strategy behind it.

One of the pleasures of the fort is its beautiful setting. The park preserves a good chunk of these barrier islands and when we visited, Rattlesnake Island was bright green with vegetation and full of bird life.

Fort Matanzas beach

Within in the boundaries of the national park, there are expansive sandy areas, both beaches and sandbars around the inlet. It’s an excellent for beachcombing. Watch out for rip currents if you swim, however. Inlets can have very strong currents.

There are free parking lots on both sides of A1A, serving a beach on the river and one on the ocean.

Tips about visiting Fort Matanzas National Monument

  • Fort Matanzas tickets: Passes for the ferry are given on a first-come-first-served basis at the visitor center and may fill up early in the day. If you are late for the tour, your seat will not be held. In winter 2022, there are six ferries, each with a capacity of 34 and they only operate Wednesday through Sunday. The ferry will not operate during lightning storms and windy conditions.
  • I think it’s better to visit Fort Matanzas before Castillo San Marcos. That way, you’re not comparing the little fort to the big one you just saw.
  • Boats and ramps are ADA compliant, so strollers and wheelchairs can access the boats.
  • While these waters are great for kayaking, you can only see Fort Matanzas with the ranger arriving via ferry.
  • Pre-pandemic, cannon demonstrations were a highlight of many visits, but are not being offered now. We hope to see them return soon.
