Taepyung Salt Farm

An embankment made the salt farm

Taepyung Salt Farm began in 1953, when an embankment closed the gap between the front and rear parts of Jeungdo. The tidal flat between them became a vast saltern, created after the Korean War to help settle displaced people and increase domestic salt production

That intervention changed both industry and geography. The current working operation spans about 4.62 million square metres. Korea’s heritage registry separately protects a 1,089,088-square-metre saltern ensemble, so the two published area figures describe different boundaries: the full operating farm and the registered industrial-heritage parcel

Seawater takes about twenty-five days to become salt

The white crystallization ponds are only the final stage. Seawater first enters storage reservoirs, then moves through a first and second set of evaporation fields. Sun and wind concentrate the brine before it reaches the crystallization fields where salt forms

The full cycle takes roughly 20 to 25 days. The grid maps that process physically: large dark reservoirs hold incoming seawater, successive ponds concentrate it, and the final shallow fields are where workers harvest crystals

From March through October, the seasonal harvesting program moves from the Salt Museum and a field explanation into hands-on salt harvesting and a traditional water-wheel activity, letting visitors follow the same production sequence at ground level

A 1953 warehouse became the Salt Museum

The farm’s heritage is built into its working infrastructure. Its stone salt warehouse dates from 1953 and is separately registered as national cultural heritage. The single-storey building now houses the Salt Museum, where the production sequence continues from seawater intake through storage and packing

The wider site keeps the museum connected to the landscape. A free observation tower looks across the full saltern, while the visitor area also includes paths through salt-tolerant plants. The visitor facilities occupy one part of the still-operating farm

The working industry also carries a labor dispute

In April 2025, U.S. Customs and Border Protection issued a Withhold Release Order on sea salt harvested at Taepyung, saying available information reasonably indicated forced labor under U.S. law. The order requires covered shipments to be detained at U.S. ports

South Korea’s Foreign Ministry disputed that description of current production. It said the documented abuse case dated to 2021, that corrective measures followed, and that salt currently exported from Taepyung was being produced without forced labor. The ministry said it would continue discussions with the United States over the order. Because the WRO is enforced against covered shipments at U.S. ports, it is regulatory context for a visit to Jeungdo rather than a physical feature of the salt-field route

Before you go

The observation tower gives the clearest first reading of the farm’s scale; the Salt Museum then explains what the separate ponds and warehouses are doing. Jeungdo is road-connected by Jeungdo Bridge, so driving to the farm does not require a ferry. The hands-on harvest program is seasonal, while the farm and museum operate year-round. The industrial process is the main attraction; the view becomes more legible once the pond sequence is understood
