Most visitors use the ocean side of Amelia Island. The west side — several thousand acres of tidal salt marsh — is the better half, and it is almost empty.
The one thing that decides everything: the tide
The tidal range on this coast is several feet. Creeks that are open water at high tide are mudflats at low. A firm strip of beach comfortably wide at low tide is water against the dune at high.
Read the tide table before every day of this itinerary. Today's high and low are on our beach conditions page, from the NOAA station at Fernandina Beach.
Nothing else on this page matters as much.
Day 1: the marsh
Morning — a guided kayak trip. The island's best experience and the one most visitors miss entirely. Narrow tidal creeks through Spartina marsh, oyster bars, hammock islands, dolphins in the river and sound, and wading birds throughout — egrets, herons, ibis, roseate spoonbills in season, ospreys and bald eagles overhead.
Go guided for a first trip. The marsh is a genuine maze, the channels look identical, phone signal is patchy, and the operator plans the route around the day's tide. Independent paddlers will find public launches on the island and at the mainland side of the bridges.
Afternoon — the Egans Creek Greenway. Three hundred acres, flat crushed-shell trails, free, and alligators resident in the creek and ponds and frequently visible from the path. Go in the last two hours of light for the wildlife.
No shade, no water, no restrooms. Take repellent — non-negotiable in the marsh from spring through autumn.
Day 2: Fort Clinch, on wheels and with a rod
Morning — the six-mile off-road bike trail inside Fort Clinch State Park, through maritime hammock. This is the best actual riding on the island and it comes inside the park entry fee, along with the 1847 fort, two beaches and the pier.
Then the pier, at the park's northern point over the mouth of Cumberland Sound. It fishes well because the sound funnels an enormous volume of water past it on every tide. A Florida saltwater licence is required for most anglers.
Even if you do not fish, this is the best vantage point on the island — cargo traffic, occasional Navy vessels bound for Kings Bay, and Cumberland Island wild and undeveloped across the water.
The jetties here are the island's best spot for fossil shark teeth and shelling. Low tide, in the gravelly bands of broken shell where heavy material sorts itself.
Afternoon — cycle the beach. The sand here is firm enough for fat tyres at low tide, and thirteen miles of it is a genuinely good ride. At high tide there is no rideable strip. Check first.
Day 3: the southern tip
Amelia Island State Park, at the bottom of the island where Nassau Sound meets the Atlantic. Two hundred undeveloped acres, no buildings, no lifeguards, and the emptiest sand on the island.
Beach horseback riding — the only Florida state park that permits it. Guided, reservation-only, and it sells out in spring and autumn. Book before you travel.
The George Crady Bridge Fishing Pier — the decommissioned span across Nassau Sound, now running most of a mile out over moving water. One of the better shore-fishing spots in northeast Florida.
Shelling and birding on the sound flats at low tide. This is the island's other good collecting beach, for the same reason as the jetties: an inlet drops what it carries.
Do not swim at the inlet. The currents where the sound meets the ocean are genuinely strong and there are no lifeguards.
Season, honestly
Spring and autumn are the seasons for this itinerary: warm water, tolerable air, fewer insects.
Summer means being off the water by early afternoon — near-daily thunderstorms from June through September, and an open marsh is a bad place to be caught in one. Lightning is the real hazard. Start at first light.
Winter is clear and quiet with cold water and short days. Best shelling, no insects, empty everything.
What to take, every day
Water, more than you think. Sun cover — the marsh and the beach have no shade at all. Insect repellent from spring through autumn. A tide table. And on the water, a way to keep a phone dry.
Extending it
Cumberland Island National Seashore by reserved ferry from St Marys, Georgia — eighteen miles of undeveloped beach, wild horses, and no shops. A full day and the best one available from here.
Big and Little Talbot Islands, twenty to twenty-five minutes south, for Boneyard Beach's fallen live oaks and five miles of undeveloped barrier beach with no ferry required.
