Pun of the word “fall”

I say yes.

My reading of it is that it's a bit poetic, and what I'm imaging is a waterfall with deciduous trees hanging over it, and in autumn the leaves fall off into it.

However, from what you've said:

Autumn comes to the waterfalls.

This doesn't really make sense in itself, except in the poetic kind of phrasing I mentioned above.

Like - summer, spring and winter also 'come to waterfalls'. It's a fairly meaningless statement by itself, unless that season has some effect on the waterfalls.

For example:

Summer comes to waterfalls and with it, boys jumping off them.

Winter comes to waterfalls and they freeze over.
