Arctic is the fourth stage in Hill climb racing. It costs 75,000 coins to unlock.
Arctic is nearly identical to Desert in the fact that it also has mostly smooth hills. The only difference is that the level itself is different and the map looks different. Cars with the downforce upgrade are great for this level because of the nearly vertical hills. Near 2000 meters into the stage, the hills become steeper and harder to climb, upgrade your suspension and engine to get up the hills.
Arctic can't earn you a lot of coins, it is mainly more for relaxing and having fun. You don't get much air time either as there aren't many hills. The easiest ways to die on Arctic is to get too much momentum after a rope bridge.
