Climbing 'Nähmaschine' (Sewing Machine), a grade 6 in the Vienna Woods, is a classic experience. The route, likely named for some perceived resemblance in the rock formation, offers a good challenge for intermediate climbers. Expect technical moves on slightly overhanging or vertical terrain. The rock type in the Vienna Woods is generally limestone, which can offer good friction but also polished holds in popular areas. The overall atmosphere is pleasant, surrounded by the lush forest. A must-do for climbers visiting the area.
