From from my knowledge, I believe finishing the wolf’s den will not take you to the snowy peak, as the wolf’s den will bring you to find another bunny, and eventually bring more tasks afterwards, from finding a new location and eventually heading to two more areas in finding the last two bunnies, then finding the last one will unlock will bring up pretty much one more task which will unlock the option (snowy peak) on the map to head to snowy peak. basically will be a straight shot with no areas between, as from my experience.
