Towering at 1,947 meters, Hallasan stands as South Korea’s highest peak, daring hikers to take on its famed trails around Seogwipo, Jeju-do. This hike isn’t just about reaching the top—it’s a dynamic encounter with a mountain fiercely alive, shifting from dense forests to rocky ridges, all leading to panoramic views that stretch across Jeju’s volcanic landscape and the surrounding sea.

The most popular route, the Seongpanak Trail, spans approximately 9.6 kilometers one way, with an elevation gain of roughly 1,200 meters. Starting from sprawling forest paths where ancient fir and cedar trees whisper above, the trail gradually steepens, challenging leg muscles as it climbs through an ecosystem that feels like a living vault of nature.

Along the way, the landscape shifts; mossy stones and rugged volcanic rock carve a jagged path upward, while the wind becomes a lively companion pushing you forward. The summit crater lake, Baengnokdam, waits at the top – a quiet, reflective pool resting in the mountain’s bowl, offering a moment to absorb the breathtaking 360-degree views.

Planning is essential for this demanding hike. Starting early in the day is wise: mornings provide cooler temperatures and clearer skies before afternoon mists roll in. Hydration is key, so pack at least 2 liters of water and energy-dense snacks. Footwear with solid traction is non-negotiable due to loose volcanic rocks and uneven surfaces.

The ascent takes about 5 to 6 hours, with the descent typically faster but requiring steady footing on the steep descent. Weather can shift rapidly, especially near the summit, so layering is critical. Though the trail is well-marked and maintained, respect the mountain’s temperament by staying on paths and acknowledging its power.

The reward for effort isn’t only the summit view—Jeju Island’s surrounding seas, the volcanic formations in the distance, and the occasional soaring eagle create a multi-sensory reward. Hallasan speaks its own language through the rustling trees and shifting clouds, a challenge and a marvel for any hiker willing to engage with its fierce presence.

Whether you’re a casual adventurer or a seasoned trekker, preparing well and embracing the mountain’s rhythms will make your Hallasan hike memorable for both the physical achievement and the close conversation with nature’s mightiest force here on Jeju-do.
