Travel northbound through Cascading Falls and you will find a place covered in snow and cheer! With bright lights, presents, music, and even the chance to meet SANTA! I hear he is in need of your help, as well as his elves. Better check in on them. However, deeper into this mountain, you will come across Ice Caverns that are not for the faint of heart. Salena (mundane) will be at the entrance of the Ice Caverns selling many useful goods for your journey deep into the caves. 
If you end up defeating the boss at the end of the caverns, make sure you return to Salena and tell her about it! (Yule Revenge)

Hunting areas here are split up into different sections for levels: 

Mount Merry 1 through 4-2 can be hunting from level 30 until around 150.

Mount Merry 4-3 can be hunted from 250 until around 360.
