Last year, I visited Nepal for two months. It is going to be very hot if you visit other parts of Nepal, but my experience also tells me that Ktm is no better than a hell for a short visit. You will see only the jungle of houses and dusty roads and Safa tampoos everywhere on the roads. As Himalaya said, i don't think it's a good idea to roam around Ktm visiting one disco or others. They are not secured places to go for in Ktm i guess. One good thing in Ktm is that there are so many supermarkets such as Bhat-Bhateni, and big stores that you get quality things easily.
