Crowd, assembly, throng, mass.
The noun 'throng' is a collective noun as a word for a large, densely packed crowd of people or animals; for example a throng of shoppers or a throng of tourists.Although the word throng (multitude) is already an unspecific collective term (i.e. less than or equal to a crowd), the plural throngs may be to indicate a larger number, or separate crowds.The verb "throng" means to gather, press, or move along together, as in moving crowds.
Mass, crowd, throng, pack, herd.
The first thing that comes to my mind when I think of a large crowd is a mob. If that is not a good word choice, then how about throng?
