When visiting Nepal's Pashupati Nath temple area, as a non-Hindu, you may not go into the temple but can see its exterior and ancillary buildings, as well as the cremations on the Bagmati river bank. For a knowledgeable and amiable guide to the area, I recommend Himiiaya (center, in white shirt; I will link to his email here if possible; UPDATE: email him or call him in Nepal at 9841498917).
And here is some of what you will see:
Cremations, performed by sons of the deceased with help from professionals.
Sadhus, Hindu holy men.
A mirror-like effect of multiple arches.
I will post more photos and recommendations about Nepal in due course.
