Asher, Peter..thank you guys. How you keeping Peter? Still in the South?
Ayesha is the one who went there, Asher. These images belong to her. She trekked from around 2200 mts to about 5200 mts.
Cars and buses are to be found here and there. But one really needs to trek, to see the splendor of this place.
To answer your question in another thread, most westerners are generally youngish, physically fit. And importantly, Bhutan has a very strict( and relatively expensive ) tourist policy and quotas. So, generally one does not see too many tourists.
Ayesha did not encounter any westerners during her trip.
