There is no actual village centre. The namesake hill, the Isterberg, with an elevation of 68 m is one of the last outliers of the Teutoburg Forest. There is a local YMCA (CVJM Isterberg-Quendorf), which serves not only the youth but also adults and older citizens as a meeting point. Furthermore, the Landjugend (Rural Youth) is also established in the community. The Landjugend organizes, among other things, a yearly tent festival well known throughout the old County of Bentheim. The small community also has its own volunteer fire brigade in which many volunteers take part.
