Best beach for collecting shells.
Check the magazines for low tide information and be sure not to take any live shells. Also be sure to wash the shells with bleach to get rid of any fishy smell and any little crabs that might be in the shells.
I was able to find many sizes and types of shells including sand dollars. Great craft project material. I have made Angels from the shells and other ornaments as well as decorating glass bowls. Shops in town have supplies needed to make many crafts as well as decorative bowls to display your shells. Be sure to wear rubber water shoes as shells are rough on your feet.
