Heuhaufen (5+) in Sektor Kaos is a true gem. This route, despite its quirky name "Haystack", offers a surprisingly diverse and engaging climb. It presents a delightful challenge with a good mix of technical sections and sustained moves on decent holds. The exposure in certain parts adds to the thrill, but the excellent bolting ensures a secure ascent. Reaching the anchors provides not only a sense of accomplishment but also panoramic views, making it a highly rewarding experience and a must-do in the sector.
