Hey dear I think you should visit Gangtok and Darjeeling this year. as last year I visited those places last year and it was an amazing experience.I saw snow fall for the first time .you will really love it.
Any place in Tasmania, Australia.. The air is so clean that you can feel the difference when you get there..
I lobe India & i think even the best place is India. You can see different weather after every 3 months. Every season is in India. Even there is 100% freedom in India.
