After many days of festival, Kathmandu streets become filthy and full of rubbish. The waste rots after long hours under the sun and is very smelly. There are no bins or garbage containers in Nepal and the waste collection system is almost non existent. The number of cows eating the rubbish is also not enough to get rid it. It was after 1 week when we started to see people cleaning some of the streets. As we discussed with some other backpackers, it is weird to see how Nepali people are used to live among the garbage and filth without even caring the smell and sanitary conditions, something that may discomfort some travellers.
