What to Bring to Shell Island: an Island With Nothing on It

Shell Island sits between St. Andrew Bay and the Gulf of Mexico, seven miles of undeveloped shoreline with no bridge and no road. Getting there means a boat, and once you're ashore, there are no facilities at all: no restrooms, no fresh water, no shade structures, no food and no trash cans anywhere on the island. Part of it sits inside St. Andrews State Park as protected habitat, which is exactly why it has stayed this way and exactly why it looks nothing like the beaches with pavilions and snack bars a few miles up the coast.

• No restrooms, anywhere on the island
• No fresh water or drinking fountains
• No shade structures, umbrellas provided, or tree cover to speak of
• No food vendors, snack bars or vending machines
• No trash cans, so everything goes back on the boat with you
• No lifeguards on duty at any point of the shore

That last point matters as much as the rest. Whatever you bring for sun, water and comfort is what you have for the day, and whatever wrapper, bottle or peel comes ashore with you needs to leave the same way. It is a genuinely undeveloped island, and that is the whole appeal of it, but it means the planning happens before you leave the dock, not once you're standing on the sand wondering where the bathroom is.

This is the short list that actually matters. Your tour handles snorkel gear, so everything below is what's genuinely on you.

• Reef-safe sunscreen, there is no shade to fall back on if you miss a spot
• Wide-brim hat or cap with a strap, the crossing has open wind, a loose hat goes overboard
• Water shoes, the sand gets hot and shell fragments turn up on both shores
• Refillable water bottle, filled before you board, nowhere on the island sells water
• Cash, small bills, for tips and any dockside extras before or after
• Dry bag or waterproof phone pouch, protects your phone on an open boat
• Change of clothes left in the car, you will be salty and wet on the ride back
• Light rash guard or cover-up, a second layer of sun protection that doesn't wash off
• Beach towel, the boats don't supply one for the sand
• Small cooler bag for anything you pack in, comes back with you, nothing stays
• Motion-sickness tablet, taken ahead of time, if you're prone to it on open water
• Sunglasses with a retention strap, easy to lose off the side of a moving boat

Every trip listed on this site supplies the water gear. Everything else on the island is on you, which is the short version of the table below.

Beyond the gear itself, the trips differ slightly in structure: the Footloose catamaran tour runs a single snorkel stop with shelling time, while the two-stop tour adds a second anchor point and more beach time. Every one of the catamaran trips with snorkel gear included covers the water gear the same way; the island itself has nothing on it once you're ashore.

You can bring a cooler and beach gear, and every boat we've worked with is fine with it, but there is nowhere on the island to buy so much as a bottle of water, so pack in whatever you plan to drink or eat and pack it back out. That includes ice, wrappers and anything else that comes ashore with you. There is no trash service on Shell Island, and leaving anything behind, intentionally or not, undoes the reason the island still looks the way it does.

A soft-sided cooler travels easier on a boat than a hard one, and it's one less thing to wrestle onto the sand. Fill your water bottle before you leave the marina; the crossing is short but the day in the sun is long, and there is no fresh water source anywhere on the island.

This is the packing category that matters most. There is no shade structure, no umbrella rental and no tree line worth the name on Shell Island, and the boat deck itself is mostly open too. Reef-safe sunscreen, reapplied rather than applied once, is the baseline.

A rash guard or light long-sleeve cover-up adds protection that doesn't wear off in the water, and a hat with a strap keeps you from losing it over the side on the crossing. If you burn easily, plan for full coverage rather than sunscreen alone; there is nowhere to retreat to once you're ashore.

Water temperature is the real driver of what you wear snorkeling here, not the calendar month by itself, and it swings a lot across the year.

None of the boats here supply wetsuits, so if you're booking a January or February trip and know you run cold, that's a rental to arrange on your own beforehand.

Shell Island earns its name on the Gulf-facing shore, where sand dollars and a wide range of shells wash up regularly, and shelling is one of the best reasons to build in time ashore rather than heading straight to the water. The rule that trips people up is a Florida Fish and Wildlife Conservation Commission rule, not a suggestion: harvesting a shell that still has a living organism inside it requires a Florida recreational saltwater fishing licence, even picked up from the sand. Take empty shells only.

• A bleached, white sand dollar is empty and fine to keep
• A brown or grey, fuzzy-textured sand dollar is alive and goes back in shallow water
• The same rule applies to starfish and any shell you can feel movement inside
• Inside the state park boundary, leave living things where you found them regardless

One more thing worth knowing before you walk the Gulf shore in summer: loggerheads and other sea turtles nest on the undeveloped part of the island, and nests are sometimes marked and roped off. Keep well clear of any marked area, don't dig near it, and don't shine a light on it if you're there after dark. Last verified: August 2026.

A short list of what not to bring saves you a problem later in the day, on the boat or on the sand.

• Glass containers of any kind, a real hazard on a boat and on bare feet
• Single-use plastic you can't easily carry back out with you
• Jewelry or anything you'd genuinely mind losing in the surf
• Food scraps meant for wildlife, since feeding any animal here, dolphins included, is not something to attempt (the honest rule on dolphins)
• A hard expectation that you'll find shade; bring your own instead

Pack light and pack smart and Shell Island gives back more than most beaches with a full parking lot and a snack bar ever do. The whole draw of the place is that it's still undeveloped, and a few minutes of planning before you leave the dock is what keeps it that way while keeping you comfortable for the day.
