I personally love Peru! The history of the Andean peoples and the rise of the Inca Empire (Tahuantinsuyo) is very interesting. The land, specially in the mountainous regions just are so beautiful it makes me want to visit the country some day! The llamas are also very adorable! ^^
Other countries like Mexico, Bolivia, Ecuador, Colombia, and others in far regions such as India, China, Japan, Australia and Kyrgyzstan are all also amazing places that id like to see one day!
Edit: Almost forgot Bhutan and Taiwan as well! So many amazing places i can't even write all!
