Münzfels is probably the second most significant tower in the Trifels area and lies to the immediate south of the most significant tower, Jungturm. The two are separated by a narrow gap which takes the form of a chimney near the ground. Jungturm is taller and skinnier and Münzfels is wider and stouter.
From the Trifels parking lot follow the obvious trail south. This is the opposite direction that the the majority of the tourists will be heading to visit Trifels Castle. After about 10 minutes, sandstone towers will begin to appear next to the trail. Take a picture or two with you to help in identifying the towers. Jungturm is a good reference point because is pretty striking. Münzfels is directly south of Jungturm.
