Sanibel Island is filled with magnificent beaches that are great for a lot more than just relaxing. The barrier island is renowned for its shell-filled shores and is often cited as one of the best places for shelling in the world. Locals and tourists alike are known for doing the so-called "Sanibel Stoop". It's a move in which you're bent over to the point that the only thing visible is your butt, the rest of you is close to the sand searching for and collecting shells. It is illegal to take live shells, so if you find a creature is still inhabiting something you find, put it back in the water. Speaking of the water, it is clear, refreshing and lovely.
