Answer:
There is another way to go south, west and north one kilometer and end up at the original point without starting at the North Pole*. Start 1+1/(2π) kilometers (approx. 1.16Km) from the South Pole. Walk one kilometer south, then one kilometer west (which is a complete 1 Km circle around the South Pole), and finally, one kilometer north to the starting point. However, there are no bears in Antarctica; there are only penguins.
In the following image, the red circle represents a one-kilometer circle around the South Pole. The purple circle is separated from the red circle by one kilometer. If you start anywhere on the purple circle and walk toward the South Pole, then, upon reaching the red circle you walk west around the South Pole, and finally you walk north to the purple circle, you will have walked three kilometers and ended up at the same place from where you started.
