About Daehoenggando Lighthouse

Also known as: Daehoenggando (Taehonggan Do)

The Daehoenggando Lighthouse, a 9-meter cylindrical concrete tower, began operation in 1965. It is painted yellow with a single black horizontal band. The focal height is 9 meters. The light emits a white flash every 15 seconds (Fl W 15s), with a geographic range of 10 nautical miles. This structure marks the end of an underwater reef near Hoenggando island. The site can be visited, but public access to the tower is restricted. It is located in the Hoenggan Sudo strait, north of Dolsando.

Why it matters: This light serves as a navigation aid for vessels transiting the Hoenggan Sudo strait, a main shipping route to Yeoja Bay. It warns mariners about the submerged reef extending from Hoenggando, helping to prevent groundings in this active channel.
