If I need to choose one country to travel to it would be Australia. Well this country is known for being really dangerous, so if you are a tourist you have to be extra careful and have your eyes wide open 24/7, so why this one? Because you can go from an extreme experience to a chill one just in a couple of hours, for example you go to a trip to the unmatched Great Barrier Reef, because if you dont get to see it you didnt go to Australia. Next day you take some surf classes, at night you are a little tired so you spend the night out watching a concert at the Sydney Opera House, and when you get out you try to find Nemo! And lastly but not less important you spend a whole day in the beach trying to get the full "Aussie experience", even though you wont be able to make it because you will be too busy looking like a basic tourist.
