Blue One Yongin Country Club's Middle Course is located in Yongin, a city in Gyeonggi Province southeast of Seoul, an area that has seen considerable golf development since the 1990s as the capital region expanded. Designed by Douglas Nickels, the course occupies terrain typical of the region—rolling hills with elevation changes that provide natural movement to the routing and varied perspectives across the property. The Yongin area's topography, characterized by forested ridgelines and valleys, lends itself to layouts where holes play through corridors of mature trees and across sloping fairways. As one of multiple courses at the Blue One Yongin facility, the Middle Course operates within the Korean country club model, where multi-course complexes serve members who often combine golf with extensive clubhouse amenities and dining. The design reflects the standards of Korean golf development from its era, with attention to conditioning and presentation that Korean golfers expect. The routing takes advantage of the property's natural contours, creating holes that require thoughtful club selection and course management on approaches to greens set at varying elevations. The course serves primarily a membership base drawn from the Seoul metropolitan area, accessible via the region's highway network. Like many Korean country clubs, the facility emphasizes service and maintains the course to high standards throughout the playing season, which runs from spring through autumn before winter conditions limit play.
