Where are you? What do you like to see/do/experience? How much time and money do you have?
Do you want to travel somewhere to sit and sunbathe or get out and experience things?
How about language?
After all things considered, I would say New Zealand. A bit of town, a lot of country. English speaking, lots of things to see and do. Outstanding scenery.
"Where to travel first?" That's your question?
To the Highest point of the world "Mount Everest".
Ecuador.
