Southwest Florida is world renowned for its shells. Have you heard of Sanibel Island? Upon arriving here, Ponce De Leon named it "Costa de Carocles" - Coast of Seashells. With over 400 species of shells, Sanibel's beaches are considered the best shelling beaches in North America.
These shells wash up on Sanibel's beaches because unlike other barrier islands which run North to South, Sanibel runs East to West.Winter is the best time for shelling, because the storms push the shells along the shallow plateau of sand along the Gulf of Mexico and deposit them along the beaches.
