While exploring Florida's 30A, I spent time at Seaside, Rosemary Beach, and Alys Beach.Terri PetersI spent time along Florida's 30A in three towns: Seaside, Rosemary Beach, and Alys Beach.Each beach town was very different, and the one I liked best felt the most "Florida" to me.The 30A beach town I'd recommend for a first-time visitor is Seaside for its great food and vibes.Florida's 30A area is a stretch of white-sand beaches, Gulf of Mexico views, and quaint beach towns that runs for 24 miles along County Road 30A.The area, which is in the Florida panhandle between Panama City Beach or Destin, has grown in popularity in recent years and has been nicknamed "the Hamptons of the South" by those who visit.Recently, I spent a few days in 30A and explored three beach towns there: Rosemary Beach, Seaside, and Alys Beach.
