South Korean families gathered in Sokcho, Gangwon Province on Wednesday, a day before reunions with relatives from North Korea at Mt. Kumgang.
The family reunions take place for the first time since October 2010.
Eighty-two South Koreans and 58 accompanying family members are to be reunited with their relatives from the North. Sixty-six are over 80.
At reunions in September that were canceled at the last minute, 96 people from South Korea and 100 from the North were to meet their relatives from the other side of the border, but 14 in the South and 12 in the North have since died or are too ill.
The South Koreans left Sokcho around 9 a.m. Thursday to travel overland by bus to Mt. Kumgang.
The reunions last from Thursday until early next week.
