Hallasan National Park, Jeju Island, South Korea, Asia

Hallasan National Park is a shield volcano located on Jeju Island, South Korea. It is the highest mountain in South Korea.

Visual Characteristics

The volcano's summit features a crater lake, Baengnokdam. The slopes are characterized by diverse vegetation, changing with altitude. Lower elevations exhibit temperate forests, transitioning to alpine vegetation near the summit. Rock formations are primarily volcanic basalt.

Location & Access Logistics

Hallasan National Park is situated centrally on Jeju Island. Access is via several trailheads. The Seongpanak Trailhead is approximately 20km east of Jeju City, accessible by National Road 1100. The Gwaneumsa Trailhead is approximately 10km north of Jeju City, accessible via Local Road 1117. Parking is available at both trailheads, with capacity limitations during peak seasons. Public bus routes 740 and 750 serve the Seongpanak Trailhead. Bus route 740 also serves the Gwaneumsa Trailhead.

Historical & Ecological Origin

Hallasan is a dormant shield volcano formed by volcanic activity over approximately 1.8 million years. Its formation is part of the Jeju Volcanic Island and Lava Tubes UNESCO World Heritage site. The park was designated a national park in 1970.

Key Highlights & Activities

Hiking is the primary activity. The Seongpanak and Gwaneumsa trails lead to the summit. Shorter trails, such as the Yeongsil Trail and Eoseungsaengak Trail, offer less strenuous options. Observation decks are located at various points along the trails. Photography opportunities exist at the summit crater lake and along the diverse ecological zones.

Infrastructure & Amenities

Restrooms are available at trailhead parking areas and at designated rest stops along the longer trails. Limited shade is available on the summit and along some trails. Cell phone signal (4G/5G) is intermittent, particularly at higher elevations. Food vendors are typically located near the trailhead parking areas; no vendors are present on the trails or at the summit.

Best Time to Visit

For clear summit views and pleasant hiking temperatures, the months of May, June, September, and October are recommended. Early morning (before 8:00 AM) offers the best light for photography of the crater lake. Winter months (December to February) can bring snow and ice, requiring specialized gear. High tide is not a relevant factor for this mountain park.

Facts & Legends

Baengnokdam, the crater lake, is said to be where a deity bathed a white deer. A specific tip for hikers is to carry sufficient water, as refill points are scarce on the trails.
