Fernandina Beach sits on Amelia Island in the far northeast corner of Florida, and it's one of the state's most underrated inshore destinations. The Amelia River, Nassau Sound, and the St. Marys River mouth create a rich estuary where redfish, flounder, and spotted seatrout thrive. The water here is tannic and tidal — it fishes more like the Georgia coast than Central Florida.
Redfish are the main attraction. The marsh creeks and oyster bars surrounding Amelia Island hold fish year-round, and the tidal swings are big enough to create serious current that pushes bait through the system. Fall is the best season — reds school up in the Sound and tail visibly on the low-tide flats on calm mornings.
Nassau Sound is one of the best Winter sheepshead fisheries in Florida. The pilings and bridge structures near Fernandina hold sheepshead in extraordinary numbers from December through March. Flounder pile up in the tidal cuts during Fall. Spanish mackerel arrive in the nearshore zone in Spring.
The Georgia border means the tidal range here is larger than elsewhere in Florida — sometimes exceeding four feet. The outgoing flow through the Nassau Sound cuts is powerful and concentrates fish predictably. Time your trips around the falling tide for the best results.
