Jefferson Beach | Serving vacationers and sun seekers since the 1920's

Did you know that from the 1920’s to the early 1950’s Jefferson Beach was an amusement park? Complete with roller coaster, carousel, fun house, arcade, dance hall and, of course, speed boat rides, the location drew large crowds during the pre-war heydays of theme parks. The old dance hall, or Ballroom, was graced by many talents over the years including Glen Miller and Guy Lombardo. Jefferson Beach officially became a full service marina in the late 1950’s.
