It depend the purpose… My choice would be Thailand, because the culture and the people make me enough relax and feeling secure that It feel right being here for holidays or the life.
There is a national park near where I used to live called Litchfield National Park and in it there is a walk called the Shady Creek Walk. I would go there any day just to get to swim in the beautiful water and be at one with the peaceful nature of the world again.
