In a metropolis dominated by soaring glass towers and subterranean transit arteries, one downtown district is making a refreshing case for slowing down and traveling on foot.

This season, the Jung District office in central Seoul is launching an expanded lineup of 11 curated walking tours designed to transform the city's historic core into an open-air museum. Running through November, the initiative builds on a highly successful pilot program that drew more than 9,400 participants last year, boasting a near-perfect 96.9 percent satisfaction rate among urban explorers.

The crown jewel of this year’s rollout is the newly minted "Yi Sun-sin Road: Birth of a Hero." The 1.3-kilometer thematic trail traces the early footsteps of Admiral Yi Sun-sin, Korea’s legendary 16th-century naval commander. Starting at Euljiro 3-ga subway station, the 90-minute trek leads history buffs past the admiral's birthplace monument at Myeongbo crossroad, through the bustling aisles of the traditional Jungbu Market, and terminates at the historic Hadogam military camp site.

For those seeking a blend of architectural heritage and local culinary lore, the returning "Tok-Tok Gwanghui Jangchung Tour" offers a more eclectic neighborhood itinerary. The route weaves past the historic Gwanghuimun Gate and the striking modernist concrete of Kyeongdong Presbyterian Church, before dropping walkers directly into the famous Jangchung-dong Jokbal (pig's trotters) Alley.
