Hidden gems

A 1.16 km² park with a deer enclosure and a marsh boardwalk. Most visitors miss it because Seongsu cafés steal attention.

A 600-year city wall walk with skyline views, but quiet because the famous part is the south ridge near N Seoul Tower.

A vinyl library and curated music collection on Hannam-dong. Free entry with any Hyundai Card; otherwise visit during open public hours.

Onion's Bukchon branch sits inside a 100-year-old hanok. Half the visitors are here for Seongsu but Anguk is the better photo.

Buddhist temple cuisine, by reservation. Quiet location at the Bukhansan foothill, full course for ~₩40,000 with weeks of lead time.

Independent poetry-focused bookstore. Tiny space, hand-picked Korean and translated literature. Open evenings.

A park built on a former landfill, now a 290m-high sea of pampas grass. Best in October; sunrise hike-friendly.

A still-local market that hasn't been polished for tourists yet. Korean fried chicken, donuts, kimchi vendors with samples.
