Mount Hallasan

The guardian of the island. Mount Hallasan is a majestic shield volcano that forms the bulk of Jeju Island. As a UNESCO World Heritage site, it offers a beautifully maintained trail network through unique basaltic landscapes and diverse flora. The trek to the summit is a full-day commitment, ascending through ancient stone-oak and fir forests into a subalpine zone. At the summit, hikers are rewarded with a direct view into the Baengnokdam—a vast crater and seasonal lake (White Deer Lake)—and, on clear days, panoramic views of the entire Jeju coastline and its surrounding volcanic 'oreums'.

Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.
