Nestled in the heart of bustling Seoul lies a hidden gem for nature enthusiasts and adventure seekers alike – Achasan Mountain. Well, technically, it is a hill that sits between the counties of Gwangjin-gu and Guri, with an elevation of 287m or 942ft.
And if you're a BTS fan, then this hill isn't really a hidden gem. You've probably seen it in a Run BTS episode when V and RM had to climb it as punishment for losing a game.
As someone who loves hiking and the thrill of exploring new places, and as a BTS fan, doing a hike on Achasan Mountain was definitely on my to-do list for my South Korea trip. So one Sunday, I woke up early and embarked on a journey to conquer this hill, eager to experience its breathtaking views.

About Achasan Mountain
Achasan Mountain, situated in the eastern part of Seoul, South Korea, is a popular destination for outdoor enthusiasts and nature lovers alike. Rising to an elevation of 287.5 meters, it offers a relatively easy yet rewarding hiking experience with stunning views of the cityscape and the surrounding Han River. It's renowned for its scenic trails, providing a refreshing escape from the hustle and bustle of urban life. I've only known about though because of Run BTS.
Additionally, Achasan is steeped in history, with ancient relics and fortifications scattered along its slopes, adding cultural significance. It was said that there was once a military fortress on this hill during the Goguryeo Era because of its location.

Hiking the Achasan Mountain Trails
Compared to other mountains I've climbed in the Philippines, Achasan Mountain was relatively easy. My only real challenge was finding the correct route to the pagoda as shown in the photo above. There are several trails on this hill, which makes it an extremely popular hiking spot for locals living in Seoul, particularly in Gwangjin-gu and Guri, and I wasn't sure which one led to the pagoda. Luckily, I met this nice lady whom I asked for directions and she was more than happy to hike with me.

The trail going to the pagoda was well-established with some steep ascents here and there, but it wasn't too difficult. I was wearing regular running shoes and it was fine, though I felt my calves burning during the ascents, which was normal. We chit-chatted on our way to the pagoda, which was just a short hike from the trailhead and she even offered to take my photos.
My original plan was to just see the pagoda but we ended up hiking all the way to the summit. We were already halfway there so why not complete the hike. The rest of the trail was quite easy as well.

It was mostly of dirt with some boulders and rocky parts. Some parts of the trail were also covered in something that looked like a coir mat, perhaps to prevent it from getting slippery, especially during the rainy season. Apart from the trail being well-established, there were lots of people hiking so it would be impossible to get lost.
Before reaching the summit, there's an observation deck where you get panoramic views of the Hangang River and Seoul. It was breathtaking.
Once we got to the summit, the views were a bit underwhelming as it was obstructed by some trees, which must be why there was this observation deck. The views were really the best there. Still, it felt great to reach the top.

After a quick rest at the summit, we made our way back on the same trail. Those who want something more challenging can continue the hike from the summit of Achasan and traverse to Yongmasan, which is another hill. It's not too high as well but it is said to be more difficult as the trail is steeper.
What to Prepare for Achasan
Since it's a relatively easy hike, you don't need to be in full battle gear. While hiking shoes or trail running shoes are always recommended, you can hike Achasan wearing regular running shoes, which is what I did. I also noticed many locals wearing running shoes. I was also wearing running shorts and my usual long-sleeved running top. This was in September so the weather was still pleasantly warm with a nice breeze. And regardless of the season, always wear sunscreen.
Of course, don't forget to bring a bottle of water. The amount really depends on your usual consumption. I brought a 500ml bottle of water and it was more than enough for me. I also didn't bring any snacks even though I didn't eat breakfast before the hike but that's just me because I'm really not used to eating in the morning.

Everyone is different so I would still recommend bringing something light to eat during, especially if you're not used to hiking. A sandwich or a chocolate bar should do it, but again it really depends on you and your eating habits. You know your body best.
How to Get to the Trailhead
While the trailhead of Achasan Mountain isn't centrally located, it's still pretty accessible. The easiest way is by taking the subway. You can take Line 5 and get off at Achasan Station, which is the nearest station. Once you exit the station, follow the signs pointing you towards Exit 2 and it will lead you directly to the entrance of the Achasan Mountain trail.
If you prefer taking the bus, several bus routes stop near Achasan Mountain. You can use online maps or apps like Naver Map to find the most convenient bus route from your location. You can also take a taxi which is a more convenient but also pricier option.

Overall, the hike would've taken around two hours going to the summit and two hours going back, not including the stops to take photos or rest. I lost track of time because I really did enjoy the hike while talking to the lady. We ended up sharing travel stories and exchanging Kakao IDs, and we even had coffee afterwards.
Whether you're a seasoned hiker or a novice adventurer, I highly recommend adding Achasan Mountain to your bucket list of must-visit destinations in Seoul, especially if you're a BTS ARMY. It was such a fun experience and I'd do it again.
