Iceland has a lower population than all of the other places Santa visits but it's near the top for believers. He has been spotted many times in the Iceland area. He spends a very long time here and not because there is a large population (which there is not) but because he needs to rest before crossing oceans and Iceland is one of his last stops before he does that.
He stays at the Reykjavik from 6 to 15 minutes. He will fly slowly and is pretty tired and he has a little break around here and some other western islands located in western Africa.
