Strongest Monsters

I have recently finished the Witcher 3 Wild Hunt main quest and most of the side quests, Now I'm level 35 and I'm looking for a challenge.
I was wondering if you guys could show me the location of some of the strongest monsters.
preferably higher than 35.

Thank You.

Never found any, but you can test your luck against city guards. I never win against guards

There is a griffin on Skellige at 48.

The strongest monster i've came across was an archgriffin in this location which i found by googling.
It could kill me by a single blow, though I beat it.
guys give me an exact location. Like this:
