For details about this crossing, please read the German version of this article or look at the tour operators website at http://www.villaohiggins.com.
In short: If you have a trailer or a lot of luggage, I recommend to take a horse for that. It’s not cheap (USD 30) but it gives you the possibility to really enjoy it.
If you don’t like to spend the night in El Chalten on the campsite, make a reservation in a hostel. In high season everything is full otherwise.
And following a few pictures from my trip with Marco and Paulo. Enjoy your trip too!
All the best,
