🌿 Seoul Autumn Hiking Gwanaksan Course – Stops Along the Trail
1️⃣ Gwanak Mountain Park (관악산공원)
The main trailhead behind Seoul National University.
A gentle forest path lined with pines and small shrines — the calm before the climb.
2️⃣ Gwaneumsa Temple (관음사)
A serene Buddhist temple built into the mountain’s slope.
Its courtyard bursts into gold and crimson each fall,
and the sound of monks’ chanting echoes softly through the trees.
3️⃣ Yeonjudae Hermitage (연주대)
A cliffside sanctuary dramatically perched on granite rock.
The panoramic view from here — Seoul sprawling beneath autumn clouds —
is one of the most breathtaking sights in the city.
4️⃣ Gwanaksan Peak (629 m)
The summit marks the highest point of the trail,
where weathered rock meets sky and hikers rest above a sea of color.
5️⃣ Gwanaksan Ridge Trail (37.4407, 126.9769)
Follow the scenic ridge toward Gwacheon.
The narrow stone path winds through red maples and golden oak —
a quieter section where the forest hums in autumn breeze.
6️⃣ Seoul Grand Park Station (Line 4)
The trail ends near a tranquil pond beside the reservoir.
Locals call this “Gwanaksan Lake Park,”
a hidden spot where maple reflections shimmer on still water.
Highlights
Ascent: Forested temple path leading to Gwaneumsa and Yeonjudae — a mix of calm, cliffs, and crimson leaves.
Summit: The granite crown of Seoul, offering a 360° view framed by mountain ridges and city skyline.

Local Food to Try 🍲
After descending to Gwacheon, stop at Seoul Grand Park Traditional Market for:
Pajeon (파전, crispy green-onion pancake) + makgeolli (막걸리, rice wine) — the classic Korean mountain combo.
Sundubu jjigae (순두부 찌개, spicy soft tofu stew) in local diners near the station.
🍵 Lucia’s Tip: After hiking, locals often share a warm pot of makgeolli and pajeon under the market tents — it’s part of the mountain ritual.

✨ Lucia’s Tip
Namhansanseong is more than a fortress — it’s a living museum of Korea’s history wrapped in autumn leaves.
Start early, walk slow, and enjoy the sound of your footsteps echoing through 1,000 years of stone and color.
🍲 Local Food to Try
Hyojonggaeng (효종갱) — A rich, slow-simmered beef and seafood soup once served to noble families in the Joseon era.
Born in the mountain villages around Namhansanseong, this dish was carried overnight to Seoul’s scholars at dawn — Korea’s first “delivery food.”
Tofu Stew (두부전골) — A hearty hotpot with fresh tofu, vegetables, and mushrooms, perfect after a cool autumn hike.
Often shared with a bowl of rice and makgeolli for a cozy mountain meal.
Acorn Muk Salad (도토리묵무침) — A light, nutty jelly salad mixed with sesame oil and spicy vegetables, offering a refreshing balance to rich stews.
Lucia’s Tip: Try these local dishes at Sanseong Village restaurants near the South Gate — the warm flavors and rustic atmosphere make the perfect ending to your fortress walk. 🍁
