The extensive range of leisure and cultural activities comes partly from districts steeped in history, such as the abbot's kitchen. The listed building Museum abbot's kitchen, a former country school from 1908, was expanded in 2002 with a local history collection. Together with the Fire Brigade Museum, Forest and Water Museum and the environmental education center the merger forms a monument and local recreation area, the MuseumsLandschaft Abtsküche.
Heiligenhaus is also known for its diverse range of events and creates its own local cultural profile with numerous cultural events. The city's culture office organizes city and museum festivals, Christmas markets, concerts, readings and much more with various cooperation partners such as the Aalto-Theater.
After a long hike or bike tour in the countryside, the restaurants, beer gardens or (farmer's) cafés along the route invite you to linger in Heiligenhaus. There are overnight accommodations in the barrier-free and bicycle-friendly city center of Heiligenhaus as well as close to nature on the outskirts.
