Achasan - A Rocky Gem with Panoramic Views

Achasan, Seoul


Having hiked over 25 mountains in the greater Seoul area and reached every summit, I can confidently say that Achasan (아차산) is one of my favorite rocky mountains. What makes it stand out isn’t just the summit itself, but the stunning viewpoints along the trail — something many hikes don’t offer.

The climb is also refreshingly short and accessible. Even with a few leisurely stops to admire the scenery or sip a quick coffee, it takes about 45 to 50 minutes to reach the top. That’s exactly why I keep returning on weekends — the combination of effort, reward, and scenic variety makes it a perfect escape from the city.

From the rocky ridge, the views of Seoul stretch in all directions. On a clear day, you can see far into the north, south, and east — sprawling cityscapes framed by distant mountains. Still, no photo or video can truly capture the beauty of standing there in person, feeling the wind, and taking in the panorama.

There are several trail entrances, but I personally prefer starting from 어울림정원 (Eoullim Garden). The trail from this point climbs steeply, almost like a 45-degree rocky path, leading up to 팔각정 (Palgakjeong Pavilion). Along the way, there are multiple scenic stopping points, perfect for pausing, looking back, and appreciating the views around you — not just what lies ahead.

Achasan isn’t just another hike in Seoul; it’s a rewarding, immersive experience that combines natural beauty, cityscapes, and just the right amount of challenge.
