Gujwa Batdam Trails & Stone Fields

The gaps are the engineering

The walls look loose because they are meant to breathe. Jeju farmers stacked porous basalt with openings that let wind pass through instead of taking its full force. The same walls slow evaporation, reduce soil loss and make exposed dry-field farming possible on a volcanic island

Jeju’s Batdam system was designated Korea’s No. 2 Nationally Important Agricultural Heritage in 2013 and an FAO Globally Important Agricultural Heritage System in 2014. FAO describes more than 22,000 kilometres of field walls built over more than a thousand years, linking the stonework directly to the survival of Jeju’s dry-field agriculture

Jinbille turns rock into a water map

Jinbille is a Jeju dialect word for a long stretch of exposed rock. The 2.5-kilometre Woljeong-ri route starts at Jeju Batdam Theme Park, passes the Jinbille Observatory and continues toward Dangcheomul Cave. The name fits a landscape where farmers had to clear and work through volcanic rock before crops could take hold

Water management is part of the route. A study of Woljeong-ri Batdam found that drainage is especially important in the local geology and that farmers adapted wall patterns to different land conditions. Along Jinbille, stone arrangements also divide rainwater routes through the fields. From the walking route, you can see graves inside the adjacent fields, each enclosed by low stone walls called sandam

Gamsugul brings the walls into village life

The second Gujwa route is shorter and more domestic. Gamsugul Batdam Trail runs 1.5 kilometres through Pyeongdae-ri, from the central community hall past a traditional thatched house to the spring that gives the trail its name

Gamsu means good-tasting water. The well was valued beyond ordinary drinking water: nearby residents used it as purification water for weddings and funerals. Around it, Batdam runs into village lanes and houses, so the same stone-building tradition appears as field boundary, wind protection and part of everyday settlement space

A global heritage system still depends on farming

FAO’s designation covers a living agricultural system. Batdam supports dry-field crops by reducing wind damage, evaporation and soil loss, and the walls continue to change with farming conditions. Research in Woljeong-ri describes the landscape as one that keeps evolving as farmers respond to different soils, drainage needs and land uses

FAO identifies farmland reorganization and urbanization among the pressures on the system. Here, conservation is inseparable from the fields: the walls still serve as boundaries, wind protection and water-managing structures within an agricultural landscape that remains in use

Before you go

Jinbille and Gamsugul are separate walks with different strengths. Jinbille is the longer, more open-field route at 2.5 kilometres; Gamsugul is a 1.5-kilometre village walk organized around the old well. Crop conditions change through the year, so the walls stay constant while the agricultural landscape around them does not
