I'm planning a trip through Chile, Patagonia and Argentina and wanting to see some spectacular sights along the way! Please let me know of any must-see sites/hotels/cities :)
I once stayed at a place called Kau Lodge near the Chile side of Patagonia and loved it. Very cheap, too!
Check out this website http://www.lonelyplanet.com/chile/tours
It offers a number of alternatives to travel.
Hope it will be useful to you.
