5) Tumen River (5 of 12)

Located right on the border of North Korea and Russia, (two countries who no one in their right minds would want to mess with), Tumen River is one of the most secure locations on the planet. There are armed guards posted on both sides of the border, and the river is generally used by people who are fleeing North Korea.

However, with all those guards and heavily fortified borders, it is a miracle if someone manages to cross Tumen River. Shawshank has got nothing on this!
