The Cimarron Course at Stonebridge Ranch Country Club in McKinney, Texas, opened in the late 1980s as part of a master-planned community development north of Dallas. Arthur Hills designed the layout to work with the rolling terrain characteristic of this part of Collin County, incorporating natural elevation changes and native vegetation into a routing that contrasts with the flatter profiles common to much of North Texas golf. The course takes its name from the regional landscape character, referencing the prairie grasslands that once dominated the area. Hills shaped the design around several creeks and water features that come into play on multiple holes, creating strategic decisions on approach shots and requiring accuracy off the tee. The routing moves through stands of mature trees and open corridors, with greens that feature moderate undulation and are protected by bunkers positioned to challenge mid-to-short iron play. The layout serves as one of two courses at Stonebridge Ranch, providing members with variety in their regular play. Stonebridge Ranch operates as a private country club within the broader residential community, offering traditional club amenities including dining facilities and practice areas. The Cimarron Course functions as the club's primary championship layout and hosts member competitions throughout the year. The course reflects Hills' approach to designing playable yet strategic golf that accommodates a range of skill levels while maintaining interest for accomplished players.
