Security ramps up near the DMZ, where South Korean leader Moon Jae-in will greet Kim Jong Un as he crosses the border from the North.
Kim will cross over under tight security on Friday (April 27) morning, the first time a North Korean leader has entered the South's territory since the Korean War.
South Korean honor guards will then escort the two to a welcome ceremony held at the truce village called Panmunjom within the demilitarized zone.
That's according to an agenda South Korea detailed on the eve of the historic meeting.
Kim will be followed in by nine officials, including his sister Kim Yo Jong, who led Pyongyang's delegation to the Winter Olympics.
He'll also be trailed by Kim Yong Nam- nominal head of state, and Kim Yong Chol. He's an ex-intelligence chief that Seoul has linked to the deadly 2010 sinking of a South Korean navy ship.
The two leaders will have lunch after their first session, and then plant a tree together using soil from two mountains on either side of the border.
Officials say at the end they'll sign an agreement, before settling down for dinner and a video titled "Spring of One."
