Tensions in Korea are heating up -- here's what the 'scariest place on earth' between North and South Korea looks like

On August 4, alleged North Korean mines seriously wounded two South Korean border guards. And on August 20, the Koreas exchanged artillery fire along their de-militarised zone, although no one was reported injured.

Today, North Korea has ordered its front-line troops onto a war footing in a drastic raise in tensions.

The Korean demilitarized zone (DMZ) is the haunted powder-keg of land left over from the Korean War that sits at the 38th parallel — 160-miles long and 2.5 miles wide.

The first stop on the way to the DMZ is Kaesong.

A couple miles south of Kaesong you'll reach Panmunjom in the DMZ.

Entering Panmunjom soldiers will stop your vehicle and force you to get out.

Here's a view of the actual demilitarized zone, which is basically farmland where few villagers have the right to live.

And on the other side you'll see South Korean guards.
