This is a book 5 in my new series of "Hiking Maps" for wonderful unearthly beautiful Patagonia, for its most famous national park Los Glaciares, of course, fully updated for 2023-24 seasons. The book contains detailed 12 hiking maps, technical details for each trail like distance (km and miles), hiking time, altitude elevation, gain and loss in altitude, visual altitude profiles, itinerary landmarks, free and paid camping sites, estancias, river fording. The book describes the major hiking trails in the park around the famous Fitz Roy and Torre mounts, but also additional less-known trails and less crowded multi-day hikes - among them: Laguna Túnel o Toro, Túnel Superior Hikes, Bahia de Hornos, de Los Tempanos Hikes. I also give information on the El Chaltén and El Calafate cities, camping sites, grocery shops, banks, bus station, bus routes and companies, then the park info, rules and prices, and how to hike safely in Patagonia, art and skills in surviving harsh Patagonian conditions, especially in the Andes region, as a hiker.
