A new area introduced in Monster Hunter Portable 3rd, the Polar Zone is an arena-like zone home only to the Ukanlos. This area is characterized by its steep ice cliffs and vast polar fields. An aurora can be seen in the night sky. Ukanlos is fought in a large ice cave with an open wall giving a view of the lowlands below. The cave roof will release ice crystals when Ukanlos roars that can damage the hunter. Temperatures here are punishingly low, and so a hot drink must be carried at all times.
- Small stones and frozen flakes on walls can be gathered to get Ice crystals.
- Two platforms can be used to switch to the left or right side without going all way around since the area is divided by a large cleavage in the ground.
- The background of the polar zone could resemble "Cold Death".
- The Roof of the Polar zone is weak to such earthquakes and strong vibrations, causing large ice to fall down and could inflict "Snowman" status if it hits the hunter.
