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.

Near the end of the stream section, the concrete blocks covering the stream are as of September 2025 completely missing, leaving you two options forward: 1) walk on a 20cm wide path right next to a big cliff, 2) walk inside of the stream bed, knee-deep in water. We decided to turn back because it did not seem safe for us. Caution recommended!
