Osorno/Puyehue, Chile
 

Nice campsite: Vista Hermosa at Puyehue, 50km's from Osorno.

We had to wait on a package for 2 nights, and found this small campsite.
Not expensive (2000 pesos per person per night, about 4USD) with Wifi and hot showers. You are at the big lake, under old apple trees and there are some chicken running around; what else could you wish for.

Nice place to hang out, and on a nice detour from Osorno to Puerto Montt if you're done with all those boring autopista's! ;-)

further info:
for those in a hurry to Buenos Aires: on this road from Osorno to the Campsite you can buy motorcycle-insurance for 10 or 30 days for Argentina. 15.000 pesos for 10 days, 22.000 pesos for 30 days. Longer was not possible.
