Posted a question on the Lonely Planet's Thorn Tree Forum the other day. The first of many for this big trip I suspect.
It's the only question remaining totally unanswered and is regarding how to get to Lauca and Isluga national parks in the far northern altiplano area of Chile. Looks like even in these days of gap years and general global exploration my goals are still a tad off the beaten path.
Watch this space for future reports on Lauca and Isluga, for me defo must sees.
