Casey Key is Sarasota's southernmost, and most prestigious, barrier island. Stretching 8 miles along the sparkling Gulf of Mexico, Casey Key is so narrow in some spots that properties are true Gulf-to-Bay residences. The real estate on Casey Key is known for being luxurious and elegant; newer homes are majestic and offer wide open views of the Bay or Gulf. Older homes are still found nestled between the mansions, and although the homes are modest, they sit on million dollar property. Casey Key beaches are pristine and private, as the Key is limited almost exclusively to high end luxury single family homes, with only a few small hotels. Casey Key is one of the most beautiful places to live in all of Sarasota.
