Three things need to be considered to be safe: being adequately prepared, the weather and natural disasters. Since there are very few services and shops in the region, you are on your own. The weather is cold due to the high elevation compared to the rest of the country and the weather can also change. Several active volcanoes are in the area, and the area is also on an tectonic plate. 112 is the national emergency number.
