Fisher Island is three miles off shore of mainland South Florida. No road or causeway connects to the island, which is accessible by private boat, helicopter or ferry. Once a one-family island home of the Vanderbilts, and later several other millionaires. If you want privacy and the best views of Miami; then Fisher Island is for you!
