Our Anna Maria Sea Salt comes straight from the shores of Anna Maria Island, Florida. Anna Maria Island is a barrier island on the coast of Manatee County, Florida. It is bounded on the west by the Gulf of Mexico, on the south by Longboat Pass (which separates it from Longboat Key), on the east by Anna Maria Sound, and on the north by Tampa Bay. Anna Maria Island is approximately seven miles long north to south. Anna Maria Island was first settled in the beginning of the twentieth century by Tampa Mayor Madison Post who then named the island for his wife Maria and his sister-in-law Anna.
