1100 Road (Jeju)
1100Jeju City to Seogwipo
Korea’s highest drivable road crosses the shoulder of Hallasan at 1,100 m, the UNESCO volcano that fills the centre of Jeju Island, linking Jeju City to the Jungmun coast.
Provincial road 1139, universally called the 1100 Road, bisects Jeju north to south across Hallasan’s flanks, cresting at the 1100 Highland wetland (a Ramsar bog with a boardwalk and island-wide views) before descending through national-park forest to the Jungmun resort coast. Cherry blossoms in spring, maples in autumn, a snow-capped Hallasan in winter.
