Whilst walking a 4-day hiking circuit, La Vuelta Huemul, starting in El Chaltén and adventuring past the incredible glacier that is the South Patagonian Ice Field, we were joined by some crazy mice. These guys made holes in our tent and food bags to nibble on our breakfast, and walked the tightrope on our tent poles. They must have been enjoying themselves, drunk on Fernet perhaps!
