Bullet hole areas != land mine areas.

Think of it this way: bullet holes are where the fighting took place, while front lines have fluctuated. You don't want to mine an area that your soldiers might want to advance through. Land mines are placed when front lines have stabilised (like they are right now in Ukraine) to prevent the other side from advancing through. You only do that once your side has no intention of advancing further.

As such, land mines were usually properly documented and clearly marked as such after the war with giant skulls and red tapes, usually with some combo of words "PAZI MINE" ("beware, mines"). So while there are still rural areas that are littered with bullet holes, that does not mean those same areas were full of mines. It's also highly unlikely for a mine to be on any road, especially if it looks fairly well-maintained. You can take a road going through the minefield just fine, but you should never be one of those urban explorers that intentionally strays off of the road to look at the ruins on the side of that road.

Might be the case, however one cannot assert 100% guarantee.

What you can do is look at the casualty rate per year and see how it went from hundreds in the 90s post-war period, to dozens throughout 2000s, to 0-1 in recent years and calculate your likelihood. Here's that chart for Bosnia: https://en.wikipedia.org/wiki/Land_mines_in_Bosnia_and_Herze...

I lived along former front lines my entire life, I spotted some unexploded ones with my own eyes a long time ago, I'm not dead yet. That said, I am more equipped to handle such situations than you are, as I was taught how to do that since my first days in school. I firmly believe that outsiders are frequently overreacting these days, which is completely understandable, but that doesn't mean it is rational. Your odds of winning a lottery are infinitely higher than dying to a landmine in the few days you spend here. You can increase them by doing something stupid like avoiding those markings, but besides that you'll be fine.
