Climbing "Dimetrodon" (grade 5) in Wasserrillen (25-30m) is a delightful experience. The route likely follows water grooves carved into the rock face, hence the name "Wasserrillen" (water grooves). Grade 5 suggests a moderately challenging climb, suitable for climbers with some experience. Expect to find holds that require thought and perhaps a few slightly awkward moves, but nothing excessively strenuous. The 25-30 meter length will provide a decent workout and a satisfying sense of accomplishment upon reaching the top. The name "Dimetrodon" probably refers to a distinctive rock feature resembling the dinosaur's sail-like dorsal fin, adding a bit of character to the climb.
