I think it's part of every girl's romantic fantasy to visit Santorini. If you've heard people rave and wow about this island, every word they say is true. And if you're wondering whether paradise can exist on Earth, yes it does. Santorini is a prime example. I absolutely loved Santorini.
Now Santorini is an island approximately 200km away from Mainland Greece. You can either take a domestic flight from Athens. I was in Turkey before I headed to Santorini, so I simply took a ferry ride (aboard a cruise ship) over. Having never been on a cruise ship before as well, it was like killing two birds with one stone.
Santorini to me is picture perfect. The night view is breath-taking. The beaches pristine and oh-so-lovely to sun tan on. If you are feeling a little adventurous, bring along your own towel and hike to less crowded areas. Sun-block is a definite must, especially during Summer.
