That is a very hard question I live where we get a little of everything. So I get to enjoy both. I would kind of think snow in the mountains more.
I love the woods. I think they are beyond amazing in the snow. I love how things look. Snow always masks what is already there , giving it a more spectatular appearance. Although, it is cold. You can still do a lot of things in the snow. You can see everything in a whole new way. Unlike, ordinary sunny days. Snow tends to make things just a little more beautiful than they are. Giving you a feeling of hope in the world. If nature can become more beautiful why can't everything else?
Its more romantic. I have had more romantic times enjoying the snow than on the beach. You can cuddle, play in the snow, go for walks and see things differently.
