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.

Difficult Route NOT suitable for children. There are areas that require climbing. Skip this route on days when the terrain may be wet (rain, snow, both on that day and in the days prior).

Access to the foot of the waterfall is dangerous and from the path, you can't see much ☹️
