Cayo Costa State Park The best shelling beach in the U.S. is not Captiva or Sanibel, the twin islands just over the mainland from Ft. Myers. There's one much better, located two islands to the north of Sanibel as the seagull flies. Nine-mile-long Cayo Costa may lack a bridge and chic hotels, but this state-park isle makes up for it with a staggering array of hard-to-find seashells.
Top 10 Florida Beaches for Seashells -- Sanibel Island, Caladesi Island State Park, Captiva Island, Cedar Key, Panama City Beach, Venice Beach, Little Talbot Island State Park, Honeymoon Island, Jupiter Island & Fernandina Beach
Why we love it: Accessible only by ferry from nearby Honeymoon Island State Park, this completely untouched, 3.5-mile-long island feels like a giant sandbar saved for the lucky few. Here, cerulean water meets radiant white sand with mounds of beautiful seashells.
