Hallasan Mountain

Rising 1,947 meters above sea level, Hallasan stands as South Korea's highest peak and the spiritual centerpiece of Jeju Island. This massive shield volcano, whose name means "mountain high enough to pull down the stars," dominates the island's landscape and offers some of the country's most rewarding hiking experiences. As part of Jeju's UNESCO World Heritage designation, Hallasan represents millions of years of volcanic activity that shaped not just the mountain itself, but the entire character of the island.

The Sacred Mountain

Hallasan holds profound significance in Korean culture and Jeju's identity. For centuries, locals have revered the mountain as sacred, believing it to be the dwelling place of mountain spirits. The mountain's changing seasons create a calendar of natural beauty that has inspired Korean poets and artists for generations, from the rhododendron blooms of spring to the snow-crowned winter peaks that seem to touch the heavens.

Geological Wonder

The mountain is a textbook example of a shield volcano, built up over hundreds of thousands of years through relatively gentle lava flows. Unlike the explosive volcanoes found elsewhere, Hallasan was formed by basaltic lava that flowed steadily, creating the mountain's characteristic broad, gently sloping sides. The summit crater, called Baekrokdam (White Deer Lake), was formed during the mountain's final eruptive phase approximately 5,000 years ago.

Unique Ecosystem:

• Vertical climate zones: From subtropical coast to temperate summit
• 1,800+ plant species: More botanical diversity than entire countries
• Endemic species: Plants and animals found nowhere else on Earth
• Living laboratory: Ongoing research into island biogeography

Hiking Trails Overview

Hallasan National Park offers several well-maintained trails, each providing different perspectives on the mountain's diverse ecosystems. Trail access is strictly regulated to protect the fragile environment, with specific operating hours and seasonal restrictions.
