This must be one of the most expensive WHS but still it is well worth visiting all 7 sites. My personal favourite is Pashupatinath, a smaller version of Varanasi and the Ganges in India. Cremation goes on day and night in the filthy Bagmati river and it is always full of locals especially on Saturdays.

Boudnath is said to be the world's largest stupa complex. Many Tibetan Gompas to visit nearby the stupa and truly a spiritual place.

Swayambhunath is a similar stupa in Kathmandu also known as Monkey Temple because of the monkeys roaming freely around it.

Changu Narayan is in Bhaktapur district and is well worth the visit. Less tourists and beautiful stone sculptures.

The 3 Durbar Squares are packed with stupas, temples, carvings, stone sculptures, etc. and in order of preference are : Bhaktapur (Bhadgaon), Kathmandu and Patan (Lalitpur). All deserve at least 1-2 days each.
