Amelia Island has two entirely different bodies of water a mile apart: thirteen miles of Atlantic on one side, and several thousand acres of tidal salt marsh on the other. Most visitors only use the ocean. The marsh is the better half, and the tide decides both.
Amelia Island's west side is a maze of tidal creeks and salt marsh feeding the Amelia River, with guided kayak and paddleboard trips running from downtown Fernandina Beach and the south end. Tide timing matters more than fitness here.

Amelia Island offers surf fishing along thirteen miles of Atlantic beach, two long piers over moving water at the island's north and south tips, inshore charters into the marsh and sound, and offshore boats from the Fernandina Harbor Marina.
Details unconfirmed
Amelia Island gets small, inconsistent surf most of the year, with the best waves arriving on winter groundswell and around passing tropical systems. It is a beginner and longboard coast rather than a destination for experienced surfers.

The working marina at the foot of Centre Street on the Amelia River, with the shrimp fleet, boat tours and charters, a public boardwalk and the island's best sunset view. The reason downtown Fernandina Beach faces the water it does.
Two beaches inside Fort Clinch State Park at Amelia Island's northern tip: Atlantic surf on the east side and calmer water by the jetties on the north, plus a fishing pier looking across Cumberland Sound to Georgia. Inside the park entry fee.

Two hundred undeveloped acres at the island's southern tip on Nassau Sound: beach, dune, marsh and maritime forest, with no buildings and no lifeguards. The only Florida state park offering guided horseback riding on the beach.
Fernandina Beach's busiest and most amenity-heavy oceanfront park, at the east end of Atlantic Avenue. Large free parking lot, restrooms, playground, volleyball, and food and mini-golf across the street — the default choice for a family beach day on Amelia Island.
About 300 acres of salt marsh, tidal creek and maritime hammock threaded with flat crushed-shell trails between Atlantic Avenue and Jasmine Street in Fernandina Beach. The island's best free wildlife walk, and reliably good for alligators and wading birds.

A Florida state park south of Amelia Island across Nassau Sound, best known for Boneyard Beach — a shoreline strewn with the bleached, salt-killed skeletons of fallen live oaks, one of the most photographed coastal landscapes in the state.

A barrier island gives you two water systems that behave nothing like each other, and the interesting one is the one behind the island.
Several thousand acres of tidal salt marsh sit between Amelia Island and the mainland, threaded with creeks. It is invisible from any road, dolphins are regular, wading birds are near-certain, and it is the best thing to do here that most visitors never do.
Kayaking is the way in. A kayak rather than a paddleboard, for a specific reason: the tidal range here is 6 to 7.4 feet and the current in the creeks is real, and a kayak handles moving water and wind in a way a board does not. See kayak or paddleboard.
Go an hour either side of high water. The creek launches want water — at dead low a lot of the back marsh is mud rather than channel and you will be dragging a boat. This single decision matters more than which outfitter you pick. Check today's tides.
Boat trips out of Fernandina Harbor Marina cover the river, the marsh and Cumberland Sound — the same water, more of it, and higher up.
Two piers. The one inside Fort Clinch State Park reaches into Cumberland Sound where the St Marys River meets the Atlantic — deep, fast water with a lot of structure. The George Crady Bridge Fishing Pier is the old A1A road bridge over Nassau Sound at the south end, kept as a pedestrian pier.
Surf fishing the length of the island, with the sandbars exposed at low tide opening up water that is unreachable at high.
Inshore charters for redfish, trout and flounder in the sound and the creeks — sheltered, shorter, and the right first charter. Offshore is a longer, rougher, more weather-dependent day. See inshore or offshore.
The rule for all four: fish the moving water. The hour either side of a tide change is when bait moves. Slack high and slack low are the dead hours.
A Florida saltwater licence is generally required, with exemptions worth checking against FWC directly rather than against a guide.
Swimming from May through October, when the monthly mean holds 76°F or better, peaking at 84.6°F in August. See water temperature by month.
Surfing, honestly assessed: the shelf here is wide and shallow, which drains energy from a swell, so the surf is usually small and best in the cooler half of the year. That also makes it a good place to learn. Our surf report reads off a NOAA buoy 17 km offshore, so what breaks on the sand is smaller than the number.
Rip currents are the real hazard. A big tidal range pushes a lot of water through the gaps in the bar system, and a falling tide with surf running is the classic setup. Most of the island's beach is unguarded at all times of year — see are there lifeguards.
Dolphins in the river and sound, regularly. Wading birds throughout the marsh. Alligators in the fresh and brackish water inland, including from the Greenway path — not in the ocean. Sea turtles nesting on the beach 1 May to 31 October. Right whales calving offshore from roughly mid-November to mid-April, which you will not see from a kayak.
Our outdoors guide lists every operator on and around the island, each with an address, telephone number and official website we confirmed on 10 September 2026. We publish no prices and no hours — we have confirmed none, and most of these businesses run by reservation and by season, so book direct.
