Unfortunately I’ll leave on January 2nd or 3d and come back on January 15th. I am planning to go by the Chilean side all the way down to Villa O’Higgins. Then Argentina, Benito Moreno Glacier, and then back to Chile, Torres del Paine and further South to Punta Arenas. From there, to Porvenir and then to Ushuaia.
On the way back I am planning to go by the Argentinean side all the way to Comodoro Rivadavia, the Bariloche and from there cross to Chile back again.
I recommend you to visit www.turistel.cl,
the South Guide and the “Rutero Camping” are really useful if you want to buy them.
