The local mountain of the Hinterberg valley, the Grimming (2.351 meters), is preceded by the Kulm, on which the largest natural ski jump in the world is located. The word "KULM" is of Celtic origin and means "upstream mountain".

The Kulm ski jump was built in 1950 and was jumped in by Hubert Neuper senior, among others. Since 1953, international World Cup events have been held here time and again.

On September 2, 2004, the official groundbreaking ceremony took place to bring the ski jump at Kulm to the most modern state of the art. The first reconstruction works concerned the new double chairlift, which mainly supports the athletes as an ascent aid.

At the FIS Ski Flying World Championships 2006, the new start house directly above the inrun track proved itself for the first time as a waiting room and snack bar for the ski flyers.

The ski flying hill is also an interesting and popular destination during the summer months. Due to its global fame, Kulm is a special attraction for many visitors and tour groups.

With the support of the Bad Mitterndorf municipal council and in cooperation with the Kulm organizing office, one of the most modern ski flying facilities has been enhanced with several exhibition and information panels. The many interested tourists, cyclists, mountain bikers, Nordic walkers, guests, and locals are presented not only with the 50-year history up to the present, but also with the latest winners and the technical data of the hill in a clear manner.

To give guests and families the opportunity to take a break at the ski flying hill, a snack bar with drinks, snacks, and WC facilities completes the offering.
