Location & Overview Hidden Harbor Marina sits at the northern end of the San Sebastian River in St. Augustine, Florida, alongside the Homewood Suites by Hilton St. Augustine San Sebastian and just a short walk from the historic district of downtown St. Augustine. Positioned a short run from the Intracoastal Waterway, the marina offers convenient access to both inland waterways and the St. Augustine Inlet while keeping boaters tucked away from the heavier current, wake, and traffic found along the main ICW channel.

Dockage & Protected Setting Hidden Harbor Marina's gated floating docks sit in a well-sheltered stretch of the San Sebastian River, with water and electric service — 30 amp, 50 amp, and 110V — available at every slip, along with ample on-site parking. The marina monitors VHF Channel 68 for boaters underway, and its quiet, tucked-away layout makes docking straightforward even for less experienced operators. Because the marina sees less current and wake than more exposed stretches of the ICW, boats here tend to accumulate marine growth more slowly — though DS Diving's underwater hull cleaning is still the most reliable way to keep hulls, running gear, and through-hull points clear between service visits, sheltered water or not.

Long-Term Slip Holders & Boat Care Hidden Harbor Marina's protected environment makes it a strong fit for long-term slip holders looking to keep their boats in good condition between cleanings and service. DS Diving supports owners here with underwater bottom paint inspections, checking coating condition below the waterline and filming the inspection so owners have a clear record of when a repaint is actually due, rather than guessing on a fixed schedule. For the occasional prop strike or ding that comes with docking in tighter quarters, DS Diving's prop pulling service can remove and reinstall a damaged propeller without pulling the boat from the water.

Facilities & Local Area Guests at Hidden Harbor Marina have access to a laundry room, restrooms with showers, and an air-conditioned public area stocked with beer, wine, cold drinks, and ice. The marina's location puts boaters within easy reach of downtown St. Augustine's restaurants, shops, and lodging, along with area marine supply stores including Sailor's Exchange and West Marine, making it a convenient home base for a day on the water or a longer stay.
