North Korea is arguably the most secretive nation in the world.
It shares long borders with China to its north, and also with South Korea. But the third, and by far the shortest, frontier is an 11-mile stretch of land it shares with Russia.
Unlike the Chinese border, the Russian one has allowed access to Google's camera cars, which can come pretty close to the Korea Russia Friendship Bridge ("Druzhny Bridge" in Russia), a rail link between the two nations.

North Korea is notoriously secretive and hidden from Google Maps' Street View function — all the areas not in blue can't be accessed on the service.
The regions of Primorsky, Russia, and Josan-ri, North Korea, are divided by the Tumen River, a 320-mile long river along North Korea's border with China and Russia. There's Google Maps imagery up to the tip of Linenaya Ulitsa, a road that stops just before the river.
Tourists in Yanbian, a Chinese prefecture that shares borders with both North Korea and Russia, can peer into North Korea at a designated observation point, where you can see the rail bridge.
