Geological Travel in Seogwipo Through columnar joints and Yongmeori Coast

The southern and southwestern coast of Seogwipo shows the timeline of the Jeju volcanic island through various cross-sections. At the Jungmun Daepo Columnar Joint, you can look down at the hexagonal columns formed by cooling lava from the observation deck, while at Yongmeori Coast, you can walk among the layers of volcanic deposits shaped by water and wind. The basalt cliffs at Baksugijeong reveal their grandeur in harmony with the coastal village.

Songaksan is a place where you can examine several craters and sea cliffs along the coastal trail, while Hallon is a massive maar crater that remains close to downtown Seogwipo. Each of the five rock formations and landscapes is different in terms of their formation causes and observation distances. Instead of touching the rocks or straying outside the designated paths, let's focus on connecting the formation processes described on the information boards with the actual scenery.

The regular columns of the columnar joints, the layering of Yongmeori Coast, the cliffs of Baksugijeong, the craters of Songaksan, and the expansive lowlands of Hallon all demonstrate that volcanic activity does not create just one shape. With the addition of seawater, wind, agriculture, and the formation of villages, geology led to the current landscape of life. Writing down the order of formation and erosion traces at each location will leave a longer-lasting impression than a single photo.

Access to Yongmeori Coast often changes depending on high tides, high waves, and strong winds, and portions of Songaksan may be restricted as well. Hallon includes agricultural lands and private properties, so make sure to only use public pathways with a view. It's important to avoid approaching cliff edges and wave-cut platforms, and confirming onsite explanations and geological park notices is a safe starting point for your expedition.
