Cristiano Ronaldo is one of the greatest football players who ever lived. Whether or not he's better than Lionel Messi is a debate that happens every day on every football forum in the world, and so we're not going to get into it here, but his talent has seen him win trophies and awards wherever he's gone, as well as breaking records. Top footballers earn incredible amounts of money, so it's unsurprising he has his own island.
Unlike many of the islands on this list, you can still visit Ronaldo's island, and take a vacation there for a reasonable price if you so desire. It's Deserta Island in Ria Formosa, close to his home of Portugal. Many observers consider it to be the most desirable location anywhere in the famous Algarve region, and it's a popular stopping point for boat cruisers, who like to spend time on its beautiful beach.
