I would agree with BWS and I would suggest bear bells. While they will do the whole Bear thing, they may make you loud enough to keep the snakes away.
I am not sure if you’re up for it but I would personally buy some snake proof chaps, pants or boots.
But much like you I have to admit to not having much experience with snakes. I actually have a total phobia of them. My joke is that I do fur, feather and fins, but not scales and slithers.
