Running across from Dongmun Market in Jeju City, Sanjicheon Stream is home to a rich array of freshwater fish (e.g. sweetfish, gray mullets, Amur goby, and carps). In summer, it attracts hundreds of thousands of anglers as well as children.

The port, downstream from Sanjicheon Stream, is renowned for picturesque views of fishing boats, egrets, and seagulls. A restored Chinese sailing vessel is exhibited at the end of the stream for visitors. Along the stream are walking paths, a park, and music fountains, in which Sanjicheon Art Festival and a slew of cultural events and performances are held every summer and winter, attracting many visitors.
