The Beaches of Fort Myers & Sanibel has been named the best place in the U.S. for shelling (collecting seashells). In fact, it's known as the Seashell Capital of the World. Here, mellow surf washes up thousands of picture-perfect seashells each day. Collect the Lightning Whelk, Lace Murex, or Alphabet Cone — all make great souvenirs. End your trip with a visit to the Bailey-Matthews National Shell Museum.
