Switzerland...

...or, to be more precise, Zermatt. Mountains, some trees, snow, snow and even more snow. That odd tree on the lower right is something you have to live with on the Mainland where every resident can build everything he wants as long as he owns the parcel.
Apart from that, there's surprisingly little eyesore in the snowy regions of old Second Life.

Just around the corner are very nice places like Snowy Secrets in Livigno or Silk Waters Mountain in Ayas and Orelle with their very affordable rental homes, or the Japanese shopping mall in Jiminy.
