Jusangjeolli Cliff
Jusangjeolli is a stretch of coastline where lava flowing from Hallasan cooled and cracked into striking hexagonal (and other polygonal) basalt columns, stacked in towers along the shore where waves crash against them — a dramatic, geometrically unusual coastal formation that draws visitors specifically for the geology. Viewing platforms run along the clifftop above the columns, with waves visible crashing against the rock below, especially impressive when the sea is rough.
It's a relatively quick stop given the compact viewing area, easily combined with other southern coast attractions near Jungmun, including the resort area's beach and other natural sights.
Jusangjeolli Cliff FAQs
Lava from Hallasan cooled and contracted as it flowed to the coast, cracking into hexagonal and polygonal basalt columns over a long geological process.
No, viewing is from platforms above the columns for safety, given the crashing waves.
20-30 minutes for the main viewing area.
Yes, it's close to the Jungmun resort area on Jeju's southern coast.
Any time, though rougher seas (common in windier months) make the wave action against the columns more dramatic.
