I adore and appreciate pure nature, however, as a solo traveler who will spend 30 hours flying and transiting on this trip (one-way) I'm not sure if I want to travel alone to enjoy pure nature. Maybe if some one who will come with me to keep me company I may consider it but to go alone with not much to do compared to Bangkok, Hong Kong, and Kuala Lumpur, I'm not really sure if it's worth the trouble of visiting there.

Put yourself in my shoes, would you travel 30 hours one way solo traveling just to enjoy nature? Good for you if you do, but for me it's not worth it. There are plenty of good places for nature such as Srilanka, Malaysia, Thailand, and Hong Kong
