Casey Key is a eight mile long barrier island on the West Coast of Florida, only 15 miles south of Sarasota. It stretches from Siesta Key on the north to Venice at the southern tip and has ready access to the Gulf of Mexico. A majority of the island is less than a quarter of a mile wide, with the beaches along the Gulf on the west and Little Sarasota Bay on the east
The island was known as "Chaise's Key" when the first map was made in 1849. It was renamed "Casey Key" in 1856 and then "Treasure Island" during the Florida land boom in the 1920s. After the collapse of the boom, it reverted back to Casey Key.
Unlike many of the barrier islands along the Gulf of Mexico coast, Casey Key consists almost entirely of single-family homes, as the island is a conservation district, established in the early 1970's by the Florida State Legislature. Ground elevations on Casey Key are generally favorable (i.e. higher) than most barrier islands, which is highly beneficial to its homeowners.
Casey Key residents get to enjoy the beaches and boating opportunities, as well as the unsurpassed sunset views over the Gulf. A quaint collection of inns is a stroll away from the public beach access and marina rentals. The twisty curves and little traffic also make for a great bike riding. In addition, top restaurants and shopping, as well as golfing and tennis are nearby. Other activities include boating, volleyball, picnicking and fishing.
