Random Encounter Tables

[othaero]

I'm creating a custom campaign and I am trying to make travel through the wilderness more dangerous. I typically don't like using Random Encounters but this campaign I trying to set the feel that the entire island is trying to kill them. I having while traveling to gain the benefits of a long rest you have to pass a DC 10 Wisdom Save (going up 2 every day you spend traveling and every combat adds 1 to the DC)

So my question is; How do you go about creating random encounter tables without it making it too difficult/often?

For me I have it every hour I roll a d20 and on 16+ something happens and even then it's not always auto attack stuff. The party can always choose to talk

The best way I've found is the random encounter chart on Blog of Holding. It isn't as "simulationist" as most charts. It's not for everyone though.
