Seoul is turning its streets, riversides and parks into an open-air autumn gallery, with the city government selecting 110 foliage trails stretching a combined 167 kilometers for residents and visitors seeking fall colors without leaving the capital. The Seoul Metropolitan Government announced Friday that its 2026 selection features tree-lined streets, riverside paths, public parks and walking trails, with peak foliage expected from late October through early to mid-November. The routes feature a variety of trees, including ginkgo, zelkova, Yoshino cherry and metasequoia, offering different landscapes across the city. The government divided the 110 routes into four categories: 20 urban walking routes, 19 riverside trails, 28 park routes and 43 walking paths. Among the highlighted destinations are Samcheong-dong Street, Deoksu Palace Road and Itaewon-ro, while visitors seeking waterside scenery can follow trails along Jungnang Stream and Ui Stream. Seoul Forest and Haneul Park are among the recommended parks, while Walkerhill-ro and Hangeulbiseok-gil are highlighted for their walking route
