The sun peeks over the horizon, casting a golden glow across the calm waters of the Gulf of Mexico as your small vessel cuts quietly through the labyrinth of the 10,000 Islands. Here, in the sheltered channels and along the private barrier beaches of Marco Island, the ocean reveals its quieter side — a world where rare shells lie just beneath the sand, waiting to be discovered. This 3-hour ShellSeeker Safari is more than a boat tour: it’s a hands-on journey into coastal ecology and local lore, guided by a seasoned USCG-licensed captain whose knowledge turns every shoreline stop into a lesson in natural subtleties.
