no, its no walser (probably).
it is a Vipera berus from the berus berus distribution.

So, how to see the difference between berus and bosniensis, when you dont know the location?
Bero, why it cant be a lowland bosniensis?

As I've already said, there is no way to be sure, except doing the DNA analysis.

There are simply no such (big) stones in their habitat. They hide and hibernate in mouseholes,
not under big stones.
Additionally, the structure/appearance of the surface of the rock. It's Alpine, or at least
reminding me of something quite high in the mountains. The only question remained WHICH
particular mountain. Whether in Bosnia or Montenegro (then it's a highland bosniensis), or
somewhere in the Alpine region (then it's a berus berus.)
