Patagonia mountain, Aguja Guillaumet, reflected in mountain guide, Pedro Fina's sunglasses

You may or may not know but in 2007 I wrote a travel and trekking guidebook to Patagonia's Los Glaciares National Park.

The book stemmed from an initial visit to Los Glaciares National Park in 2005 to do the Southern Patagonia Icecap traverse. When I returned to Scotland, I sold some pictures of the west face of Cerro Torre to the now-defunct High Mountain Sports magazine and wrote a few articles detailing my trip which, after about a year of effort and another trip for research purposes, turned into a whole book about the park which was subsequently published by Sergio Zagier, owner of Argentine book publishers, Zagier & Urruty.

Sergio contacted me last month to say that we were coming to the end of the print run, having sold 1000 copies. Which is way above my initial expectations and pleases me immensely. So I wanted to do two things. Firstly, say a public thanks to Sergio and to everyone who has bought the book - I hope you found it useful and informative and would agree that Fitz Roy and Cerro Torre are the most stupendous mountains to see - but also to advertise it to those who haven't, but are perhaps organising a trip to Patagonia. It's simply an amazing place to go and I believe, although things will have changed a lot administratively since I last visited, I still do have the most comprehensive and up-to-date trekking guidebook to Los Glaciares National Park.
