Daegwallyeong-myeon is originally part of the Gangneung city. It was transferred to Jeongseon county in 1906. It then became part of Pyeongchang county in 1931. The original name was Doam-myeon. It was then renamed to Daegwanryeong-myeon after the Daegwallyeong pass that connects Gangneung with this location. This results in Gangneung being more connected to Daegwallyeong-myeon than the rest of Pyeongchang.
