When October arrives in South Korea, the sweltering summer heat completely vanishes, replaced by a crisp breeze, clear blue skies, and a breathtaking natural transformation. Across the city, green trees erupt into vibrant shades of crimson red, warm orange, and golden yellow. Known locally as Dan-pung (단풍 – Autumn Foliage), this seasonal spectacle is one of the most magical times of the year to explore the capital.

If you want to experience the best autumn colors in Korea without rugged hiking or grueling mountain climbs, Seoul’s expansive urban parks are the absolute best choice. Connected conveniently by the city’s subway network, these massive parklands offer glowing tree tunnels, wide-open lawns, and romantic lake walks right within easy reach.

Here are the Top 3 Autumn Foliage & Picnic Parks in Seoul to Visit This October!

1. Seoul Forest (서울숲): The Golden Ginkgo Canopy in the City

• Location: Seongdong-gu, Seoul
• Nearest Transit: Seoul Forest Station (Suin-Bundang Line), Exit 3 or Ttukseom Station (Line 2), Exit 8
• Best Time to Visit: Mid to late October
• Vibe: Trendy, artistic, relaxed, and incredibly photogenic

Why It’s a Top Foliage Pick:

Located right next to the ultra-hip Seongsu-dong neighborhood, Seoul Forest is often called Seoul’s answer to New York’s Central Park. Covering over 1.16 million square meters, this expansive park features densely planted forest zones, deer enclosures, mirror ponds, and pedestrian bridges. During autumn, the park turns into a mesmerizing sea of red maples and golden ginkgo trees.

Highlights & Photo Spots:

• The Golden Ginkgo Forest (은행나무 숲): The park’s most famous autumn highlight is a dense grove of towering Ginkgo trees. Walking down the narrow pathway beneath a brilliant ceiling of vibrant yellow leaves feels like stepping straight into a movie set!
• Culture & Art Park Lawn: Grab a picnic mat (mat-teu) and sit under a red maple tree with takeout coffee from Seongsu-dong’s trendy cafes.

💡 Local Tip: Combine your visit with a walking tour of Seongsu-dong (성수동) right next door—famous for pop-up stores, artisan bakeries, and industrial-style cafes.

2. Olympic Park (올림픽공원): Rolling Golden Hills & Iconic Autumn Vistas

• Location: Songpa-gu, Eastern Seoul
• Nearest Transit: Olympic Park Station (Line 5 & Line 9), Exit 3 or Mongchontoseong Station (Line 8), Exit 1
• Best Time to Visit: Late October through early November
• Vibe: Expansive, majestic, historical, and family-friendly

Why It’s a Top Foliage Pick:

Built for the 1988 Seoul Summer Olympics, Olympic Park is a massive green oasis in eastern Seoul known for its undulating green hills, historic earthen fortress walls (Mongchontoseong), and open sculpture gardens. In October, the entire terrain shifts color: the surrounding forests turn brilliant red, while the grassy fields transform into warm golden hues.

Highlights & Photo Spots:

• The Lone Tree (Na-hol-lo Na-mu – 나홀로나무): Standing solitary in the middle of a vast, rolling grass field, this famous tree framed by autumn skies is one of the most iconic photography spots in all of Seoul.
• Wildflower & Autumn Reed Fields: Adjacent to the green hills, large fields of autumn cosmos flowers and feathery silver reeds (Eok-sae) sway gently in the crisp fall wind.

3. Seoul Grand Park (서울대공원): A Mountain-Framed Autumn Lake Escape

• Nearest Transit: Seoul Grand Park Station (Line 4), Exit 2
• Best Time to Visit: Mid to late October
• Vibe: Grand, picturesque, spacious, and immersed in nature

Why It’s a Top Foliage Pick:

Located directly on Seoul Subway Line 4 at the base of Cheonggyesan Mountain, Seoul Grand Park offers an incredible nature escape seamlessly integrated into the metropolitan subway network. Because it sits within a dense mountain valley, the sheer scale of autumn foliage here is unmatched by inner-city plazas.

Highlights & Photo Spots:

• The Grand Park Lake Reservoir Walkway: A scenic 2.2-kilometer walking loop around a wide mountain lake. The reflection of the red and yellow mountain trees in the calm water creates breathtaking panoramic views.
• The Elephant Train & Sky Lift: Take the open-air Sky Lift cable car floating high above the lake and tree canopy for an unforgettable bird’s-eye view of the fall colors.
• The Zoo & Botanical Garden Trails: The paved walking trails winding through the Seoul Grand Park Zoo are lined with old-growth maples and ginkgos, offering a quieter, peaceful foliage walk.
