Smoking has been banned at the some of the most popular beaches at the Cape Cod National Seashore. Superintendent George Price says smoking will be prohibited at all six of the park's guarded beaches beginning June 19.

Price says that secondhand cigarette smoke ``ruins the experience'' of non-smokers at the beach. Millions of people visit the national park every year.

The smoking ban covers Coast Guard Beach and Nauset Light Beach in Eastham, Marconi Beach in Wellfleet, Head of the Meadow Beach in Truro, and Race Point Beach and Herring Cove Beach in Provincetown.

Visitors will be allowed to smoke at non-guarded areas.
