For us the best way to offset the high cost of airfare is to put together several trips. Using Santiago as a hub, we are touring Bolivia, Northern Argentina, and northern Chile as a circuit. The Bolivia side of Lake Titicaca, the great salt flats and the wine country will take us a month to move through. Leaving from Santiago again, we will go south to Patagonia and Torres Del Paine National Park and the Glaciers National Park in Argentina and some penguin viewing will be another couple weeks. Leaving from Santiago the final time, by ship, we will finally be able to see Antartica. The 21 day cruise will spend a few days near the Antarctic peninsula but does not “land” there. We finish in Buenos Aires and will stay in Argentina another 10 days or so before the caravan life beckons again.
