This book is the 2nd edition of my travel guide about wonderful Torres del Paine National Park. I updated: 1) all factual information, prices and conditions for current season 2020-2021; 2) added miles/foot data to all measures in metric system as km/m; 3) added 1x big general map, and 6x hiking maps for each trail, so that now the guide contains 8x maps in total. This is a unique and the most complete "smart" travel guide, which I made, at first, to be solely used in my own, after buying so many travel guides and still feeling - they aren't good enough for my adventures to explore wilderness as a biologist and wildlife/travel photographer. I was missing it during my trip to Patagonia in 2017, otherwise, I would be much more efficient as a wildlife photographer and traveler. I hope the book will be a good “practical tool”, an all-to-know set of guide books for you (for me as well), while you are exploring the world with responsible mind and open heart as a truly nature lover. The book contains 100+ GPS coordinates of important to know places, 50x website links, covering all the important campsites, hotels, viewpoints, trails, key sightseeing, it has 8x detailed trekking maps, and 15x photographs I made in March-April 2017. The book first describes how to get in/out the park, all park’s updated rules and prices, then how to design your trekking route and how to book all accommodation in the park and nearby. In addition to popular “W” and “O” trekking circuits in the park, I give information about another 6 less-known, secret “off-the-bitten-pass” trails with hiking maps for each. I also give all the details for wild and paid camping, hotels, hostels, domes, cabins, food stores, roads conditions, travel scenarios, public buses, prices for touristic services, paid tours, wildlife safaris, fishing, kayaking, horseback riding. At the end of the guide, I give detailed information what kind of wild animals and where you can meet in the park (puma, condors, huemul, guanaco, fox) and their behavior. I also describe where you can find fossils from Jurassic Era of ichthyosaur, of a large prehistoric marine dolphin-like predator, or to see ancient cave paintings of indigenous tribes lived here 3000-8000 years ago. The book can be equally useful for "budget" adventure seekers, solo/group travelers, "fast & easy" with a rented car/campers or travel agency users as well as for paid wildlife and travel photographers on a mission. Printed versions of the book just went far beyond of my anticipation; quality is highest standard possible, they are rather small (15x23 cm), light-weight (only ~150 g each), fully colorful inside with maps and GPS coordinates, pages are robustly made and glued, the cover is made of water-repellent paper, books are flexible, you can bend them, nothing will happen... though, they are ideal to put them into your backpack and use them while you travel through wonderful Patagonia... Enjoy and take care!
