Guidebook to trekking in the heart of Patagonia, with routes in Torres del Paine National Park (Chile) and Los Glaciares National Park (Argentina). While the region is primarily a remote and mountainous glaciated wilderness, walking is easily accessible with clear trails, good public transport and regular mountain huts and campsites.

The centrepiece of this dramatic area is the 10-11 day Torres del Paine Circuit (also known as the 'O' Circuit), while the shorter Half Circuit (the 'W') visits much of the same sights in 4-5 days. The guidebook also includes four shorter day walks, a multi-day trek in Argentina's Los Glaciares national park, and several excursions from Puerto Natales and El Calafate.

This guidebook includes advice on getting to and around the regions, languages, visa, currency, accommodation and facilities in the National Parks, as well as useful guidance on what to take and expect on the treks. Also featured is background information on the geology, history, wildlife, flora and cultures of the regions, resulting in an excellent companion guide to help you explore the region.
