St. Augustine was founded by Spanish colonists in 1565 — making it the oldest continuously occupied European settlement in the continental United States. The city's entire history is tied to its waterfront: the Matanzas River, the St. Augustine Inlet, and the Atlantic Ocean that both sustained the colony and exposed it to centuries of attack, hurricanes, and trade. The Castillo de San Marcos — the oldest masonry fort in the continental US, completed in 1695 — sits directly on the Matanzas River waterfront, its coquina stone walls still perfectly intact after 330 years.
From the water, St. Augustine's layered history comes alive in a way impossible from land. The Bridge of Lions, the Spanish Colonial downtown, Flagler's grand hotels (now part of Flagler College), and the ancient streets running back from the bayfront all reveal themselves in perfect tableau. Boat tours on the Matanzas River are one of the best ways to experience the city, complemented by the surrounding tidal marshes and the spring-fed rivers accessible by kayak to the west.
The Castillo de San Marcos is the oldest masonry fort in the continental US, built from coquina shell stone quarried on Anastasia Island directly across the Matanzas River. Coquina — a soft limestone made of compressed shell fragments — proved uniquely resilient against cannon fire: rather than shattering, it absorbed cannonballs. The fort has never been taken by force in over 300 years of military history. Seeing it from a boat on the Matanzas River — massive, ancient, right at the water's edge — is one of the most striking historical experiences in all of Florida.

Sea Serpent Tours provides the definitive St. Augustine water experience. The Matanzas River tour passes the Castillo de San Marcos at close range — the sheer scale of the 17th-century fort is overwhelming from water level. Continuing south, the tour covers the old city bayfront, the Bridge of Lions (a 1927 drawbridge with sculptural lions at the entrance), Anastasia Island, and the open waters of Matanzas Bay. The river and bay are active dolphin habitat, and manatees make seasonal appearances. The river route option explores the inner marsh waterways for a quieter, more wildlife-focused experience.
One of the best day trips from St. Augustine is west to Florida's spring country. Poe Springs County Park (40 minutes by car) offers kayaking on the Santa Fe River with a beautiful spring boil pumping 72°F crystal-clear water year-round. AOA Fun operates guided and rental kayak experiences at the springs. An hour west, the Ichetucknee River is one of Florida's most beloved spring-fed waterways — 6 miles of tubing or paddling through a pristine first-magnitude spring run with manatees, turtles, and extraordinary clarity. The springs are magical in winter when manatees concentrate in the warm water.
The Guana Tolomato Matanzas (GTM) National Estuarine Research Reserve surrounds St. Augustine with miles of protected salt marsh and tidal creek habitat. Kayaking the GTM's winding waterways is a completely different experience from the historic river tour — remote, quiet, and extraordinarily rich with bird life. Roseate spoonbills, white ibis, great blue herons, ospreys, and dozens of other species inhabit the marsh. Dolphins regularly work the tidal creeks on the incoming tide.
St. Augustine offers guided boat tours on the Matanzas River past the Castillo de San Marcos, land-and-sea combination history tours, tidal creek kayaking in the GTM Reserve, dolphin watching cruises, sunset sailings, fishing charters, and day-trip access to Poe Springs and the Ichetucknee River (spring kayaking and tubing). The city's 500-year waterfront history makes boat tours uniquely memorable.
Yes — St. Augustine has excellent kayaking. The salt marsh tidal creeks of the GTM Estuarine Reserve offer excellent wildlife paddling right in the city's backyard. For freshwater spring kayaking, Poe Springs County Park (40 minutes west) and the Ichetucknee River (1 hour west) are among the best spring paddling destinations in Florida. Multiple outfitters in the area offer rentals and guided tours.
Sea Serpent Tours runs guided boat tours on the Matanzas River and surrounding waterways. Their bay route covers the main St. Augustine historic waterfront — Castillo de San Marcos, Bridge of Lions, and the old city skyline. Their river route explores the tidal marsh interior for wildlife. Both include historical narration on St. Augustine's extraordinary past from Spanish settlement through the Flagler era.
St. Augustine is approximately 40 miles south of Jacksonville — about 45–50 minutes by car via I-95. Many visitors combine a Jacksonville flight arrival with a St. Augustine day trip or overnight stay. The combination of America's oldest city's water activities with Amelia Island to the north makes the Northeast Florida region an excellent multi-day water sports destination.
