A constant of the theatre scene in Caldaro (Kaltern) is the Theatergruppe Kaltern, founded in 1986. Every year, it delights its audience with a new play, with a clear focus on comedies and farces.

The Heimatbühne Kaltern also enriches the local theatre scene, primarily with cabaret performances in the town's community hall. For example, the programme has included ‘Das perfekte Desaster Dinner’ by Marc Camoletti, in an adaptation by Michael Niavarani. A special summer highlight is the open-air cabaret on the grounds of the Kettmeir winery, where the well-known duo ‘Prantl & Prantl’ provides excellent entertainment.

To ensure young talent is also nurtured, there is the ‘Innenseite’ children's and youth theatre. The young company is mainly active between October and June and performs regularly at the children's theatre festival in the neighbouring town of Appiano (Eppan).
