It is an important historical pass that connects the regions of Yeongseo and Yeongdong.
This mountain pass was used for delivering agricultural and marine products from Gangneung to Yeongseo.
Daegwallyeong is located at a height of more than 800 meters (2,600 ft), so overall, the annual average temperature is lower, and the precipitation is higher than that of other parts of the Republic of Korea.
In spring, as the Siberian air fleet retreats, it is not relatively cold, and only the chilly weather continues.
In particular, due to the high atmospheric pressure of the North Pacific Ocean, southwest air currents blow in and the characteristics of the windy areas, torrential rains are more frequent.
