I'm contemplating an overland advernture trip starting in Southeast Asia (possibly Malaysia or Singapore) to South Asia, ideally to the Hunza Valley in Pakistan, but just getting as far as any entry point to India, Nepal, or Pakistan might suffice.
I see there are some mountains in my way. There are also some countries not easy to pass through, like Burma (Myanmar), some borders which might not be open, or at least not to non-locals (I have an Australian passport), some conflict zones, and the non-triviality of entering Bhutan.
So it seems there are potentially routes both south of the mountains through various countries, depending on what's possible after taking into account the above; and north of the mountains across an apparently large expanse of China, about which I don't know much. (How stupid of me! That area is Tibet, which requires special permits to enter so also may not be too easy...)
Which of these routes is the more possible, safe, and/or affordable?
