A small train takes visitors several hundred feet underground to see the "Third Infiltration Tunnel." It is one of four tunnels discovered by South Korea, allegedly built by North Korea to launch an invasion of South Korea. This tunnel is reportedly large enough to allow 30,000 fully armed soldiers to travel through.
