Icirrus City. To begin with the landscape has a lot of diversity-- there are caves, moors, ponds and the imposing site of Dragonspiral tower. However, what really draws me to this area is how beautiful it is in winter. It was during Christmas time that I first played Pokemon Black, which gave me the pleasure of experiencing beautiful snows in-game as well as outside my own door. This area in particular stood out. Icirrus city's frozen, glassy lakes, snow-covered windmills and cottages made me feel like I had stumbled across an illustration from a book of fairytales.
The best part is that when the snow is piled high you can journey to special areas by climbing on top of the snow, spots that are not accesible at any other time of year. Everything you run into from Beartic to Sawsbuck in its winter form perfectly compliments the wintry atmosphere. It is cool to have a secret place up there to visit where higher level Pokemon wait.
