The Heart of Seoul Leisure In early 2026, the Seoul Metropolitan Government and local residents continue to celebrate Yeouido Hangang Park, Seoul Forest, and Olympic Park as the city's essential top three green spaces. These locations serve as vital urban retreats for both citizens and international business travelers. Consequently, they offer a perfect blend of accessibility, massive scale, and diverse cultural events. Each park provides a unique thematic experience ranging from waterfront relaxation to historical exploration. Therefore, understanding their specific features helps visitors maximize their time in the capital. Yeouido Hangang Park: The Waterfront Hub Yeouido Hangang Park sits at the center of the financial and political district in Yeongdeungpo-gu. It spans 8.4 kilometers along the river and covers 1,487,374 square meters of land. Specifically, the park remains the most accessible riverside destination due to its proximity to Yeouinaru Station on Subway Line 5. This location makes it a favorite for office workers. The park features the Bamseom Ecological Center and the Saetgang Ecological Park. These areas preserve natural wetlands and offer VR experiences to educate visitors about the local environment. Furthermore, the Mulbit Square and the Piano Waterway provide refreshing water features for families. In contrast, sports enthusiasts use the football fields, swimming pools, and inline skating rinks. The 2026 Cherry Blossom Festival will occur from April 8 to April 12. During this period, over 1,600 cherry trees create a spectacular pink canopy along the Yeouiseo-ro walkway. Notably, the park hosts the Global Fireworks Festival every autumn. Consequently, millions of visitors gather on the grass lots to enjoy the massive displays over the Han River. Seoul Forest: The Ecological Gem of Seongsu Seoul Forest opened in June 2005 on the former site of the Ttukseom horse racing track. It occupies approximately 480,994 square meters in the trendy Seongsu-dong neighborhood. The park organizes its space into five distinct themed areas. These include the Culture and Art Park, the Nature Ecological Forest, and the Wetlands Ecological Field. Indeed, the Ecological Forest allows visitors to observe wild animals like deer in a protected environment. Additionally, a pedestrian bridge offers a unique view of the surrounding woods. The Nature Experience Study Field includes an Insect Botanical Garden and a Butterfly Greenhouse. These facilities offer educational programs that run throughout the year for all ages. Similarly, the Mirror Pond and the Fountain are popular spots for photographers and couples. The park remains open 24 hours a day, though some specific facilities follow set schedules. Olympic Park: A Legacy of Sports and History The city completed Olympic Park in August 1986 to support the Asian Games and the 1988 Summer Olympics. It covers 1,447,122 square meters in the Songpa-gu district. This massive site harmoniously combines the ancient Mongchon Fortress with modern international stadiums. Therefore, it functions as a bridge between Korea's historic past and its athletic future. The KSPO Dome stands as a central feature with a capacity of 15,000 seats. Consequently, it serves as the premier venue for major K-pop concerts and global music festivals. Other athletic facilities include the Swimming Pool with 10,000 seats and the Velodrome with 6,000 seats. These venues continue to host professional competitions and public sports programs. Cultural landmarks like the World Peace Gate reach a height of 24 meters. Additionally, the Lone Tree on the rolling grass fields remains one of the most iconic symbols of the park. Yeouido, Seoul Forest, and Olympic Park define the green infrastructure of modern Seoul. They provide essential spaces for environmental preservation, public health, and massive cultural consumption. These three parks continue to enhance Seoul's reputation as a world-class living environment.
