Olympic Park in Seoul is a sprawling urban oasis built for the 1988 Summer Olympics, offering a blend of historical sites, gardens, and recreational spaces. The park is generally accessible with paved paths, though some areas may have limited access for wheelchairs. It's suitable for both solo exploration and guided tours, depending on your interests. Spring (cherry blossoms) and autumn (fall foliage) are peak seasons, but the park is open year-round, with seasonal events throughout. Expect to spend anywhere from a few hours to a full day exploring, and costs are minimal, primarily for transportation and optional activities or rentals within the park. Public transportation is recommended due to the park's size.
