Tips from the Community
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!

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).

The final few meters of the ascent and descent are quite exposed in places and are not secured with ropes. Experienced climbers are recommended.
