Capsule: Driving west across the Venetian Causeway toward Miami, the third of six islands you come to is Dilido Island. Largest of the mid-Venetian Causeway isles, homes on the nothern end of Dilido have spectacular open water. Most of the other waterfront homes either look across to Dilido Island to the east or San Marino island to the west. A fair amount of replacement of older homes with new larger estates is taking place on this isle.
