The video shows a group of people walking through a tunnel made of ice. The tunnel is tall and narrow, with the walls and ceiling made entirely of ice. The people are wearing cold weather gear, including jackets and helmets, to protect themselves from the cold. The lighting in the tunnel is dim, with some light coming in from the end of the tunnel. The group is moving slowly and carefully through the tunnel, with some people stopping to take photos. The ice tunnel appears to be quite long, and the group seems to be exploring it for the first time.
