Which country should i travel to?

I recently watched the movie Eat, Pray, Love and it inspired me to travel. The summer after my senior year i'm going travel to another country but need help deciding which to go to. I want to go somewhere beautiful and breathtaking, with amazing culture and landscape. Somewhere where i can meet new people, learn, and explore new things. Also maybe learn something new about myself, and others around the world. Help!?
