Why You Should Actually Come Here
Hallasan is Korea’s highest peak at 1,947 meters, and unlike most “must-see” destinations, it actually lives up to the hype. I’ve done this hike five times now—twice in spring, twice in summer, once in early autumn—and it’s genuinely worth the trip. What gets me every time is that you can stand on top of South Korea looking at a crater lake, and most of the tourists still haven’t figured out the place exists. The views aren’t just nice; they’re actually stunning, and the hike itself feels real—hard enough to be satisfying, not so brutal that you’ll hate yourself.
Getting There
From Seoul, you have a few options. The easiest is taking an express bus directly from Seoul Express Bus Terminal (강남고속버스터미널). The trip takes about 3.5 hours and costs 25,000 KRW one-way. You’ll arrive in Jeju City. From there, catch a local bus (number 1 or 2) heading to Seogwipo for 3,500 KRW, then transfer to bus number 71 or 72 headed to Hallasan National Park. Total travel time from Seoul is roughly 5 hours if you time it right.
Here’s the thing most guides miss: the buses from Jeju City to the park don’t run frequently after 5 PM. I showed up at 4:47 PM once thinking I had time, and the next bus wasn’t until the next morning. Plan to arrive at the park entrance by early afternoon if you’re doing this as a day trip. There are actually two main entrance routes—Seongpanak (성판악) on the east side and Gwaneumsa (관음사) on the west. Seongpanak is slightly longer (9.6 km to summit) but easier; Gwaneumsa is shorter (8.7 km) but steeper. Most people pick Seongpanak because the bus drops you closer.
If you’re renting a car, parking at Seongpanak costs 3,000 KRW for cars. The entrance fee to the national park is 2,000 KRW for adults. You pay this at the gate before starting the hike.
What to Do / See
The Main Hike
The summit push starts early. The park opens at 5 AM, and if you’re serious about reaching the top, you need to start by 6:30 AM. The rules are strict: all hikers must descend by 3 PM, no exceptions. This isn’t negotiable. Rangers will turn you back if you haven’t reached certain checkpoints by specific times. I’ve seen people turned around at 1 PM when they were close, so don’t risk it.
The Seongpanak route is mostly forested for the first 3 kilometers. It’s pleasant—wide paths, minimal elevation gain, good for warming up. Around the 4 km mark, the forest thins and you get your first real views of the island. The air gets noticeably cooler. At 5.8 km, you’ll hit the tree line. This is where things get real. The final 3.8 km to the summit is exposed, rocky, and windy as hell. Bring a windbreaker even if the weather looks perfect in the morning.
The summit itself has a crater lake called Baengnoktdam (백록담). On clear days, you can see all the way to the south coast. The rim walk around the crater is maybe 30 minutes if you’re slow. The whole experience takes 4-5 hours roundtrip from Seongpanak if you’re moving steadily.
What Disappointed Me
The summit building. There’s this small building at the top that serves drinks and snacks. It’s incredibly overpriced—4,500 KRW for a bottle of water that costs 1,500 KRW at the bottom. But more annoying is that on busy days (weekends, school holidays), it’s crowded and you can’t enjoy the views quietly. On my third visit in May during a school holiday, there were maybe 200 people crammed at the summit. I wish I’d gone on a weekday.
Other Areas Worth Time
If you’re not hiking the full summit or have extra time, the visitor center near the Seongpanak entrance has decent exhibits about the volcanic geology. It’s air-conditioned and free. The walking trails around the park entrance are easy and pleasant—nothing dramatic, but fine if you don’t want to commit 5 hours to the main hike.
The eastern side of the park near the park entrance has some smaller walking courses. The “Dongbu Jeju Olle” is a 1.5-hour walk with views of agricultural terraces and the coast. It’s crowded with older Korean tourists, but genuinely relaxing.
Where to Eat / Practical Tips
Bring your own food. This is crucial. I learned this the hard way. There’s a small convenience store at the park entrance with overpriced triangle gimbap (3,500 KRW) and drinks. That’s it. Pack a substantial breakfast before you arrive—carbs and protein. Two boiled eggs, rice, maybe some cheese. You’ll burn through serious calories on this hike.
Once you finish and head back to the entrance area, if you need lunch, the small town of Songup (송업) near the park has some decent local restaurants. There’s a place called Jeju Black Pig Restaurant (제주흑돼지) where you can get decent grilled pork for 12,000-15,000 KRW per person. Nothing fancy, but real food after a 5-hour hike. Ask a taxi driver to take you there—it’s about 15 minutes from the park entrance.
Bring way more water than you think. The wind at altitude is dehydrating. I usually carry 1.5-2 liters and refill at the entrance. Sunscreen, trekking poles, and proper hiking shoes are non-negotiable. The paths are rocky and unpredictable. I’ve seen people in sneakers slip on loose rock.
Honest Take
Go if you actually like hiking. Don’t go if you’re expecting a scenic stroll. This is a real hike—challenging enough that some people turn back. The best time is late September through early October when the weather is cool and stable. Avoid weekends if possible; weekdays are quieter. Spring is beautiful but unpredictable—snow at the summit as late as April. Summer is sweaty and misty. My one regret from early visits is not realizing how early you genuinely need to start. That 6:30 AM departure feels punishing, but it makes the difference between a great experience and a rushed, frustrated one. If you’re fit, have proper gear, and don’t mind getting up before dawn, this is legitimately one of the best hikes in Korea. If those conditions sound annoying, skip it.
