Danyonggul (Jeonchon Yonggul) is a sea cave at Jeonchon Beach in Gampo, Gyeongju, sitting alongside Saryonggul. Waves meet the cave, and the sunrise is visible from it. A wooden deck path leads up and down past stairs to the Haeparang Trail. The path just before the cave is rough and the waves are strong, so entering the cave is difficult.
