Gatbawi, Tafoni rock formation in Mokpo, South Korea

Gatbawi consists of two sandstone rock formations that rise from the harbor area of Mokpo's east shore, reaching heights between 6 and 8 meters. The structures display natural erosion patterns and surface textures carved into the stone over time.

Gatbawi was long reachable only by ferry; a pedestrian bridge, Bohaenggyo, was built in 2008 so visitors could walk out over the sea to the rocks. In April 2009 it was designated Natural Monument Number 500 of South Korea, and it is counted among the eight famous spots of Mokpo.

The rock formations connect to Korean folktales through their names and appearance, resembling traditional bamboo hats worn in the region. They hold meaning in local storytelling and appear frequently in regional art and photography.

Gatbawi sits by Mokpo's east harbor at the mouth of the Yeongsan River. A pedestrian bridge built in 2008 now links the shore to the rocks, which were reachable only by ferry before. The site is open daily from 06:00 to 23:00; the shoreline rock can be slippery, so wear shoes with grip.

The two rocks are named separately: the larger is called Jeongbawi, the "father", and the smaller Satgatbawi, the "son". The hollows began where water seeps into cracks in the exposed sandstone block; once a pit opens, shade keeps it damp and it grows inward faster than the surrounding surface.
