For many travelers, climbing Hallasan is not simply another thing to do in Jeju.
It is the moment when you finally understand how the entire island was shaped around one enormous volcano.
The summit destination is Baengnokdam, Hallasan's famous volcanic crater at the highest point of South Korea.
But don't think only about the summit.
The journey up the mountain changes constantly.
You begin beneath a dense forest canopy.
You pass shelters and volcanic forest.
The trees gradually become smaller.
The sky becomes wider.
And eventually the forest disappears behind you as you climb the exposed upper slopes toward Baengnokdam.
This guide follows that journey from the trailhead all the way to the summit.
Forest → Shelters → Volcanic Landscape → Alpine Zone → Baengnokdam
π¨ Important Hallasan Update — August 2026
August 1 – September 30, 2026
The upper section of the Gwaneumsa Trail between Samgakbong Shelter and Baengnokdam is temporarily closed for rockfall-prevention facility work.
During this period, hikers can reach Baengnokdam only by using the Seongpanak Trail.
The lower Gwaneumsa Trail remains accessible from the entrance to Samgakbong Shelter.
If you are reading this guide after September 2026, check the official Hallasan website before assuming the Gwaneumsa summit section has reopened.
πΊ️ Hallasan Summit Map
For the current August–September 2026 period, use Seongpanak if your goal is Baengnokdam.
π️ Going to Baengnokdam?
Advance reservation is required for the summit-access section.
Book Hallasan Summit Accessπ© Seongpanak to Baengnokdam at a Glance
⛰️ Summit: Baengnokdam
π One-way distance: 9.6 km
⏱️ Official ascent estimate: About 4.5 hours
πΊ Seongpanak → Jindallaebat: 7.3 km
⛰️ Jindallaebat → Summit: 2.3 km
π Trail entry begins: 05:00
⏰ Summer summit-direction cutoff: 12:30 at Jindallaebat
⬇️ Summer summit departure deadline: 14:30
π» Toilets: Trailhead, Sokbat Shelter, Jindallaebat Shelter
π Shop on trail: None
The distance is the main challenge.
The early trail is not extremely steep, but a Seongpanak round trip is approximately 19.2 km.
That makes pacing much more important than trying to climb quickly.
π₯Ύ Stage 1 — Seongpanak Trailhead
Your journey begins at the Seongpanak Trailhead on the eastern side of Hallasan.
The first thing you notice is not the summit.
It is the forest.
Much of the Seongpanak route is hidden beneath trees, so the beginning feels very different from the exposed volcanic landscape you eventually reach near Baengnokdam.
The gradient is relatively gentle through much of the early section.
π
My Practical Advice
Do not plan your hike around the latest allowed entry time. If you want to enjoy the scenery, rest comfortably and reach Baengnokdam without watching the clock all morning, start early.
π² Stage 2 — Sokbat Shelter
The first major rest point worth remembering is Sokbat Shelter.
The route to this point is dominated by Hallasan forest.
Instead of looking for a dramatic viewpoint, pay attention to the vegetation and volcanic terrain around the trail.
This is the part of Hallasan where the mountain still feels quiet and enclosed.
Sokbat is also useful because there is a toilet here.
π Don't Wait to Buy Supplies
There is no shop along the Seongpanak trail. Bring enough water, food and emergency snacks before you begin.
π Stage 3 — Sara Oreum Entrance
This is where you have an interesting decision to make.
Along the Seongpanak Trail is the entrance to Sara Oreum, one of Hallasan's most interesting side destinations.
A side trail of roughly 600 meters leads toward the Sara Oreum observation area.
Depending on conditions, the crater area can hold water and create a beautiful high-altitude wetland landscape.
There are also views back toward Hallasan and across the surrounding oreum landscape.
⏱️ Summit First
If Baengnokdam is your priority, do not automatically add Sara Oreum on the way up. The Hallasan summit route has strict control times. On a slow day, I would prioritize reaching Baengnokdam first rather than spending too much time on a side trip.
πΊ Stage 4 — Jindallaebat Shelter
Jindallaebat Shelter is one of the most important places on the entire climb.
It is approximately 7.3 km from Seongpanak.
By the time you reach this point, the easy forest walk is largely behind you.
The summit is only 2.3 km away, but that final section is much harder than the distance suggests.
There are toilets here, making this an important place to stop before the final ascent.
In the flowering season, the surrounding mountain azaleas also add color to this high-altitude landscape.
⏰ Summer Control Point
For the current April–September schedule, hikers heading toward Baengnokdam must pass the Jindallaebat control point before 12:30.
If you arrive too late, you will be required to turn back.
πͺ Stage 5 — The Forest Begins to Disappear
This is where the character of Hallasan changes.
Above Jindallaebat, the trail becomes significantly more difficult.
The official trail grading changes to the most difficult level for the final approach to Baengnokdam.
The trees become lower and thinner.
The sky opens.
You begin climbing longer stair sections across the exposed upper slope.
On a clear day, the view behind you expands across Jeju Island.
This is also where the wind and weather can feel completely different from the forest below.
π¬️ Don't Trust the Weather at the Trailhead
Hallasan weather can change quickly. A warm, calm morning below can become windy, cold, cloudy or wet near the summit. Carry an extra layer even when Jeju City feels warm.
π️ Stage 6 — Baengnokdam
Then you reach the reason most hikers came.
Baengnokdam.
The name is usually translated as “White Deer Lake.”
The enormous volcanic crater sits inside Hallasan's summit rim.
On a clear day, the crater walls, volcanic rock and broad sky create one of Jeju's most memorable views.
But remember:
You are not guaranteed a perfectly clear crater view.
Cloud and fog can arrive quickly around Hallasan's summit.
That unpredictability is part of climbing a high mountain.
You Have Reached the Roof of South Korea
⏰ Don't Stay at the Summit Too Long
It is easy to forget the time when you finally arrive.
People rest.
Take photographs.
Eat.
Wait for the clouds to move.
But Hallasan has a mandatory summit departure time.
⬇️ Summer Summit Departure
From April through September under the current schedule, hikers must leave the Dongneung summit area by 14:30.
You still have a long descent ahead of you.
Save enough energy for it.
𦡠The Descent Is Often Harder Than Expected
Many people focus entirely on climbing up.
But after reaching Baengnokdam, your legs may already be tired.
The long descent repeatedly loads the knees and ankles.
Do not rush just because the hard climb is finished.
Take controlled steps.
Use trekking poles if you are comfortable with them.
And keep drinking water even while descending.
π§ What About the Gwaneumsa Trail?
Under normal conditions, Gwaneumsa is the other trail that connects with Baengnokdam.
It is 8.7 km one way and the official hiking estimate is approximately 5 hours to the summit.
It is shorter than Seongpanak but generally steeper and more dramatic.
Major places along the route include:
π³️ Guringul Cave
A lava-related cave reached early in the route.
π Tamna Valley
One of the route's major valley sections.
π² Ant Back Ridge
A demanding forested climb.
⛰️ Samgakbong Shelter
The major checkpoint about 6 km from the trailhead.
π️ Yongjingak Valley
One of the most scenic high-mountain sections.
π️ Baengnokdam
Normally another 2.7 km beyond Samgakbong.
π§ Current 2026 Closure
Until September 30, 2026, do not plan to reach Baengnokdam through Gwaneumsa. The Samgakbong–Baengnokdam section is closed.
π When Both Summit Trails Are Open
When the full Gwaneumsa route is operating normally, there is another good option:
Up Seongpanak → Baengnokdam → Down Gwaneumsa
Why?
Seongpanak gives you a more gradual ascent.
Gwaneumsa gives you a more dramatic valley and ridge landscape on the descent.
But the two trailheads are in different locations.
You need to plan transportation rather than expecting to return to the same parking lot.
π What Should You Carry?
✔ Plenty of water
✔ Food and energy snacks
✔ Hiking or walking shoes with good grip
✔ Light waterproof layer
✔ Extra warm layer
✔ Sunscreen
✔ Hat
✔ Fully charged phone
✔ Portable battery
✔ Trekking poles if you normally use them
Disposable lunch containers are restricted in Hallasan National Park.
Pack food in a way that creates as little waste as possible, and carry all garbage back down with you.
π¦️ Always Check the Mountain Before Leaving
A reservation does not guarantee the mountain will stay open.
Hallasan access can be restricted because of:
π§️ Heavy rain
πͺ️ Typhoon conditions
π¬️ Strong wind
❄️ Heavy snow
π«️ Dense fog
⚠️ Other dangerous mountain conditions
π‘ Check Before Departure
Use the official Hallasan reservation and National Park pages for the current trail status and live CCTV before traveling to the trailhead.
π¨ Who Should Climb to Baengnokdam?
π₯Ύ Travelers comfortable with long hikes
The summit route is a full-day mountain activity.
π Geology travelers
You finish the hike looking directly into Hallasan's volcanic crater.
π· Landscape photographers
The environment changes dramatically from forest to exposed summit.
π️ Travelers who want a major Jeju challenge
This is very different from visiting an easy oreum or viewpoint.
πΏ Nature travelers
The changing vegetation is part of the experience, not simply the final view.
π₯ Who Should Consider a Shorter Hallasan Route?
You do not have to climb Baengnokdam to enjoy Hallasan.
Consider another route if:
❌ A 19 km day is beyond your current fitness
❌ Knee or ankle problems make long descents difficult
❌ You cannot begin early
❌ Weather near the summit is poor
❌ You are traveling with very young children
❌ You prefer scenery without a full-day endurance hike
Routes such as Yeongsil and Eorimok offer excellent Hallasan scenery without reaching Baengnokdam.
❓ BEST 3 QUESTIONS
1. Which Hallasan trail reaches Baengnokdam in August 2026?
Seongpanak. From August 1 through September 30, 2026, the upper Gwaneumsa route is temporarily closed between Samgakbong Shelter and Baengnokdam.
2. How long does it take to climb from Seongpanak to Baengnokdam?
The official one-way estimate is approximately 4 hours 30 minutes over 9.6 km. Actual time varies significantly with fitness, weather, rest stops and trail congestion.
3. Do I need a reservation?
Yes, if you plan to enter the controlled summit section and climb to Baengnokdam. Make the reservation through the official Hallasan Trail Reservation System.
⭐ A Local's Final Advice
Don't climb Hallasan thinking only about the photograph at Baengnokdam.
The mountain changes several times before you get there.
Enjoy the forest below.
Stop at Sokbat.
Notice the Sara Oreum junction.
Rest properly at Jindallaebat.
Then watch the trees disappear as you climb into the open summit landscape.
Baengnokdam is the destination.
But the changing landscape on the way there is what makes Hallasan feel like much more than a long staircase to the top.
If you remember the entire climb rather than only the summit, you have experienced Hallasan properly.
