Marco Island: Dolphin, Birding & Shelling Tour in 10,000 Islands

Summary

Marco Island wildlife tour with dolphins birds and island shelling

You’ll ride deep into the 10,000 Islands from Marco Island with a naturalist guide, watching dolphins play and spotting rare birds before landing on an untouched barrier island for shell collecting. Feel salt air on your skin as you wander white sand searching for sand dollars or just listening to waves. It’s peaceful but never boring — and you might leave with more than just shells in your pocket.

What’s the experience like?

“That’s a dolphin — right there!” our guide whispered, and everyone went quiet except for the slap of water against the boat. I’d read about the 10,000 Islands but didn’t expect to feel so small out here, mangroves everywhere and that salty air sticking to my skin. Our Florida Master Naturalist (I think his name was Jim? Or maybe Tim… I was distracted by a pelican dive-bombing nearby) pointed out osprey nests tucked into branches like messy treehouses. He had this way of making every bird seem like an old friend — “That’s Carl,” he joked, nodding at a heron who looked mildly offended.

I kept fumbling with my phone trying to catch the dolphins surfacing — always just missing them. The sun felt thick on my arms, but there was this breeze that kept it from getting heavy. We skimmed past clusters of egrets and spoonbills, their pink feathers weirdly bright against all that green. Someone behind me said they could smell the tide before we even reached the barrier island (they weren’t wrong). When we finally stopped, stepping off onto sand that squeaked underfoot, it was just us and a scatter of shells — some perfect spirals, some chipped but still pretty in their own way.

I tried to say “rosette spoonbill” in Spanish because Li dared me; she laughed so hard I nearly dropped my bag of sand dollars. The guide showed us how to spot living shells versus empty ones — apparently you’re not supposed to take anything still alive (makes sense). We wandered around picking up little treasures until someone realized their kid had found what looked like a fossilized crab claw. The whole thing felt both quiet and kind of giddy at once. I still think about that view back toward Marco Island — sky wide open, nothing but bird calls and our own voices echoing over the water.
