We spent a total of about 2 months hiking in the Alps, staying on campsites and cooking our own meals on a multi-fuel stove. We moved often between different areas, but rarely over very long distances, and avoided lifts and cable cars, instead hiking all the way up the mountains. Our average expenses per day, for the two of us, were about 46 EUR.
