Caution! Approaching Irumugarrieta Peak from the south, you have to climb a serious, vertical wall. Unfortunately, with a dog, we had to give up here and fought our way down cross-country through the undergrowth. The other way around, it probably won't work with a dog even without abseiling. The tour is still very beautiful, but I wouldn't do the special descent again.
