Namhae Garlic Fields: Terraced Farming on a Southern Island

Namhae Island's terraced garlic fields (남해마늘밭) are a network of small hillside farms that have been cultivated for centuries by island communities using hand-built stone retaining walls to create level planting terraces on steep south-facing slopes. The island's mild climate — moderated by the warm South Sea — and its mineral-rich volcanic soil produce garlic with a distinct sweetness and pungency prized across Korea. The fields are concentrated in the Changseon and Seolcheon areas, where the stepped terraces create a visual staircase running from the ridgelines down to the sea.

Namhae garlic has been cultivated since at least the early Joseon period and appears in historical records as a tribute product sent to the royal court. The island's isolation — it was accessible only by boat until a bridge was built in 1973 — preserved traditional farming methods that have been lost elsewhere in Korea. The terracing technique used on Namhae is similar to that found in Bali and the Yunnan province of China, and agricultural historians have used it to study the diffusion of terrace farming across East Asia. Namhae garlic now carries a geographical indication certification from the Korean government.

The fields are most spectacular from late March to May when the garlic plants form a dense green carpet across the terraces, and again in late May to early June when the scapes (flower stalks) curl dramatically before harvest. Several farms welcome visitors to participate in the manual harvest in June — an experience involving communal work and shared meals. The Namhae Garlic Festival held in late June celebrates the harvest with cooking competitions, garlic product markets, and traditional farming performances.

The best photographic viewpoints are on the hillside above Changseon village, accessible via a short unmarked track from the main road. Garlic products — braided strings, black garlic, and garlic-infused oil — are sold at farm stalls and the local cooperative at significantly lower prices than in supermarkets. The fields are accessible by local bus from Namhae town, with a 10-minute walk to the main terrace area.
