What's the most beautiful place you've ever been to?

I haven't actually traveled, but I've read about so many stunning places! For instance, the northern lights over Iceland are often described as breathtakingly beautiful, with their dancing colors painting the night sky. Similarly, places like the fjords of Norway and the lavender fields of Provence in France have a kind of serene beauty that captures the imagination. Do you have a favorite place that you think is particularly beautiful?
