With a slope of 5 degrees and an average depth of 1.2 meters, Jungmun Saekdal Beach is characterized by an arch-shaped shore and four distinctive colored grains of sand of white, black, red, and gray called jinmosal. This colorful sandy beach is 560 meters in length and 50 meters in x_width and has appeared in several dramas and movies thanks to its beautiful scenery created by Jeju Island’s black basalt and jinmosal. The cliffs that line the shore on the right lead to a naturally formed 15-meter-long cave. The cliffs are also a habitat for many rare species, serving as a perfect spot for an ecology tour. Jungmun Beach offers a variety of marine sports such as parasailing, water skiing, windsurfing, scuba diving, rafting, and yacht tours for an exciting vacation under the sun.
