Lake Kilpisjärvi is a cool lake up in the far north of Finland and Sweden, near where the borders of Finland, Sweden, and Norway meet. It's split into two parts, Kilpisjärvi and Alajärvi, surrounded by big mountains like Saana. This place is frozen most of the year because of its high elevation and northern location. So, if you're into icy lakes and stunning mountain views, this spot is definitely worth checking out!
