The Audi Course at Hartl Resort in Rotthalmünster, Bavaria, was designed by Bernhard Langer in collaboration with Kurt Rossknecht and opened in the early 2000s. Langer, Germany's most accomplished professional golfer and a two-time Masters champion, brought his competitive experience to this design in the rolling countryside of Lower Bavaria, not far from the Austrian border. The course reflects his preference for strategic shot-making and precise iron play, characteristics shaped by decades of tournament golf. The layout occupies gently undulating terrain typical of the Bavarian lowlands, with mature trees framing many holes and water features coming into play on several. The routing takes advantage of natural elevation changes to create variety in stance and approach angles. Rossknecht's involvement brought technical expertise in course construction and agronomy suited to the region's climate and soil conditions. The design emphasizes playability for a range of skill levels while maintaining enough challenge to test accomplished players, a balance Langer has pursued in his design work. Hartl Resort operates as a golf and leisure destination with multiple courses on the property, and the Audi Course serves as the flagship layout. The facility includes practice areas, instruction programs, and resort amenities that cater to both traveling golfers and regional members. The Bavarian setting provides a pastoral backdrop, with views across farmland and forest characteristic of the Inn-Salzach region. The course has hosted regional amateur competitions and serves as a venue for corporate outings, reflecting its dual role as both a serious golf test and an accessible resort course.
