At the same time, the restaurant enjoyed greater and greater popularity. It lured – especially after the railway to the Saalburg had been built – more and more townspeople into the country. After World War II the Zwermann family cultivated the Lochmühle grounds.
The founder of the park, Theo Zwermann, was forced to give up agriculture for health reasons and decided to start breeding ponies. With the purchase of the two Shetland ponies Heidi and Susi he laid the foundation of a riding centre. His two daughters had a lot of fun with the ponies and their friends also came to the Lochmühle to ride. As time passed, a riding centre developed, which at times, up to the end of the 70s, accommodated up to 70 horses.
