Daepo Jusangjeolli Cliff is a natural monument located on the southern coast of Jeju Island in South Korea. The name Jusangjeolli means "a high cliff with regular patterns of hexagonal stone pillars," and the rock formations here are made up of volcanic basalt columns that have been naturally formed over time by the sea.

These pillars are particularly striking because they are tall, evenly shaped, and appear to have been carved out with precision. The hexagonal shape of the pillars is due to the cooling and solidification of the lava flow that formed them.

Visitors can enjoy a scenic walk along the coastal trail, which provides a stunning view of the cliff and the ocean. The area is also surrounded by lush vegetation, which adds to the beauty of the landscape.

Daepo Jusangjeolli Cliff is considered one of the top attractions on Jeju Island and is often included on tourist itineraries. It is also a popular spot for photographers and nature enthusiasts who come to capture the beauty of the landscape.
