Jusangjeolli Cliff

Overview

Jusangjeolli Cliff is a striking formation of hexagonal basalt columns along the Jungmun coastline, created when volcanic lava from Hallasan flowed into the sea and cooled rapidly. The symmetrical, pillar-like rock columns resemble a giant stone wall and are designated as a Natural Monument of South Korea.

Highlights

• Hexagonal Columns: Remarkably uniform basalt columns stretching along the coast, each appearing hand-carved.
• Dramatic Waves: The southern coast's strong waves crash against the columns, creating spectacular spray.
• Coastal Walk: A scenic paved pathway along the cliffside offers multiple viewpoints.

History

The columns formed when lava from Hallasan erupted and reached the ocean approximately 250,000 years ago. The rapid cooling of the molten basalt created the characteristic hexagonal jointing pattern. The site was designated Natural Monument No. 443.

Visitor Tips

• Best in Wind: Windy days produce the most dramatic wave action against the columns.
• Combine With: Adjacent to the Jungmun resort area and Cheonjeyeon Waterfall.
• Duration: 20–30 minutes.
