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.

These types of tunnels are those of the old mining train route, since, due to the difficult orography, they had to be excavated to avoid the slopes of the mountain.

The Aitzondo waterfall is located in the Aiako Harria natural park, at the western end of the Pyrenees. This waterfall is one of the largest in Guipuzcoa, with a drop of 140 meters that ends in a small pond.

The old mines of Meazuri exploited iron carbonate, which was very abundant in the area. The mineral was very abundant, but its metallic grade was very low, so it was later treated in calcination furnaces to transform it into iron oxide. This procedure considerably enriched the ore, eliminating impurities and increasing its metallic grade between 10 and 20%. Today the route of the old mining train and the tunnels that were excavated to avoid the slopes of the mountain are still preserved.
