Cheonjeyeon Waterfalls, Three-tier waterfall system in Jeju Island, South Korea.

Cheonjeyeon (천제연폭포) is a three-tier waterfall in Jungmun-dong, Seogwipo, on Jeju Island. The first cascade drops 22 m into Cheonjeyeon Pond, 21 m deep; the second falls 30 m and continues to a third before the water reaches the sea. The first fall is dry most of the time and only forms after heavy rain, while the second and third flow year-round. Columnar-jointed cliffs surround the upper pond.

The surrounding forest around the falls became a designated Natural Monument in 1993 due to its ecological and scientific value. This protection recognizes the importance of the warm temperate woodland ecosystem in this region.

The Seonimgyo Bridge spans the waterfalls with carvings of seven nymphs who, in local legend, descended from heaven to bathe in the pools. This story shapes how visitors understand and experience the site, giving the water and stone their own meaning.

Marked paths guide visitors to viewpoints at each cascade level, and the bridge provides a central viewing spot for the entire system. The terrain is fairly walkable, though sturdy footwear helps since rocks near the water can be slippery.

Marbled eels, designated as Natural Monument number 27, live in the deeper pools below the cascades and are rarely seen by visitors. Their presence shows how the falls and surrounding forest create a special habitat for this rare species.
