My friends and I are visiting Torres del Paine in about 3 weeks or so. We get in fairly early on day 1 and leave roughly mid day on day 3. That leaves most of the first and all of the second day open for hiking. Does anyone have suggestions? We're all in our 20s, in pretty good shape and relatively well accustomed to hiking. We were also thinking of camping instead of staying at a hotel, so any ideas would be appreciated.
