Following Gyeongpo Beach, a total of 86 beaches in Gangwon Province are set to be fully opened starting from Monday to July 12, including the renowned Sokcho Beach, Jeongdongjin Beach and Yangyang Surfyy Beach, according to the province.

Daecheon Beach, the iconic beach along the west coast in Boryeong, South Chungcheong Province and home of the Boryeong Mud Festival, welcomes visitors from Monday to Aug. 18.
