Complete Guide to Hallasan National Park in Jeju

About Hallasan National Park

Hallasan National Park sits at the heart ofJeju Island, built aroundSouth Korea's highest mountain at 1,947 meters. The park is actually a UNESCO World Heritage site, and for good reason - it's home to an incredibly diverse ecosystem that ranges from subtropical forests at the base to alpine vegetation near the summit. The mountain itself is a shield volcano that's been dormant for about 5,000 years, though you'll find plenty of evidence of its volcanic past scattered throughout the trails. What makes Hallasan particularly special is how it encapsulates Jeju's unique character in one place. You might start your hike among tangerine groves and bamboo forests, then find yourself walking through ancient lava tubes and past crater lakes. The mountain tends to create its own weather system, so don't be surprised if you encounter completely different conditions as you climb higher. It's the kind of place that gives you a real sense of why Jeju feels so distinct from mainland Korea. Entry fees are ₩3000 ($2) with parking typically ₩2000 ($1). The tranquil setting creates an ideal setting for exploration, where details revealing themselves reveals intricate architectural details and natural formations. Visitors often notice the distant chatter and feel of smooth stone beneath their hands as they navigate through different sections. Practical tip: Consider visiting during sunset for spectacular photo opportunities. The combination of historical significance and sensory experiences makes this destination particularly rewarding for those who take time to engage with both its cultural heritage and natural beauty.

What to See & Do

Baengnokdam Crater Lake

The summit crater lake that's worth the challenging hike - a serene body of water sitting in what was once the volcano's mouth, though access can be restricted depending on weather conditions

Seongpanak Trail

The longer but more gradual route to the summit, winding through diverse forest ecosystems and offering glimpses of Jeju's unique flora along the way

Gwaneumsa Trail

The steeper, more direct path that's popular with serious hikers - you'll encounter some genuinely challenging sections but also some of the park's most dramatic scenery

Yeongsil Trail

A more accessible option that doesn't go all the way to the summit but takes you through some beautiful rock formations and offers decent views without the full commitment

Seasonal Wildlife and Flora

Over 1,800 plant species call this place home, including some you won't find anywhere else - the autumn colors are particularly spectacular, and spring brings wild azaleas

Practical Information

Opening Hours

Generally open from sunrise to sunset, but summit trails often close by early afternoon (around 1-2 PM) for safety reasons. Winter access to the summit is frequently restricted due to weather conditions.

Tickets & Pricing

Free entry to the national park itself, though you'll need to register at trail entrances. Parking fees apply at most trailheads (usually around 2,000-5,000 KRW).

Best Time to Visit

Late spring through early fall offers the most reliable weather, though each season has its appeal. Avoid typhoon season (July-September) if possible, and note that winter summit attempts require proper gear and experience.

Suggested Duration

Summit hikes typically take 8-10 hours round trip, while shorter trails can be done in 2-4 hours. Plan for a full day if you're going to the top.

Getting There

Rent a car. The trailheads scatter around Hallasan's base, and you'll want freedom to hop between them without checking bus schedules. Most access points sit 30-45 minutes from Jeju City. Bus 740 connects several hiking entrances. But the service runs infrequently-expect long waits between rides that could eat into your hiking time. Total waste of daylight. Driving makes sense if you're staying in Jeju City or Seogwipo anyway. You'll probably want to explore the rest of the island between hikes. Why limit yourself?

Tips & Advice

Check weather conditions obsessively - Hallasan creates its own microclimate and conditions can change rapidly, especially near the summit

Start early if you're attempting the summit, as trail access often closes in early afternoon for safety reasons

Pack layers and rain gear regardless of the forecast - you'll likely encounter different weather zones as you climb

Bring more water than you think you need, especially in summer, and consider packing some Korean trail snacks from a local convenience store
