Seonim Bridge, Arch footbridge over Cheonjeyeon Waterfall, Jeju, South Korea

Seonim Bridge is a steel arch footbridge 128 metres long, 78 metres high and 4 metres wide, weighing 230 tonnes. It crosses east to west over the stream between the second and third tiers of Cheonjeyeon Waterfall on Jeju Island. Its steel columns carry 14 nymphs, seven per side, each about 20 metres long and playing a musical instrument, alongside 100 balusters and 34 stone lanterns.

Completed in 1984, Seonim Bridge was the first bridge in the region built with an Ojakgyo design. The Korea Tourism Organization spent about ₩400 million on its construction. It was built to link Cheonjeyeon Waterfall with the Jungmun Tourist Complex.

The bridge is also called Chilseonyeogyo, Seven Nymphs Bridge, after the legend of seven nymphs descending from heaven at night to bathe in the Cheonjeyeon waters. The 14 nymphs on the steel columns, seven per side and each about 20 metres long, all play their own musical instruments.

The bridge is pedestrian-only and links the Cheonjeyeon waterfall tiers with the Jungmun Tourist Complex, so it can be crossed on foot in either direction. A fee applies to tourists using the bridge. Its 34 stone lanterns are lit at night, making an evening crossing possible.

The bridge connects two different levels of the three-tiered waterfall formation, offering an unexpected viewpoint of the cascades from above. This positioning allows visitors to experience the falls from a perspective that ground level views cannot provide.
