Lochmühle has two of these Heege Butterfly roller coasters set parallel to each other and with the entrances facing each other. This entry is for the Butterfly that is furthest the river that bisects the park and closest the replica mill.
The park map lists the name of these two roller coasters as "Pendelbahnen", which is simply the plural form of "Pendelbahn" or in English "Pendulum Track". This Pendelbahnen name does not appear on or near the ride, but "Butterfly" does. Whenever these name discrepancies occur, the name found on the ride is assumed the most accurate.
