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. This is my 3rd book in the "wilderness explorer" series (the first one I wrote about Peninsula Valdes, the second - about Torres del Paine National Park, see it at 13 Amazon webstores: www.amazon.com/dp/B078RC9QC2), which I hope, 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 245 GPS coordinates of important to know places, 70 website links, covering all the important campsites, hotels, viewpoints, trails, key sightseeing, it has 2 detailed trekking maps, and 20 photographs I made in March-April 2017. The book first describes how to get in/out the "Tierra del Fuego" park and Ushuaia, all park's updated rules and prices, then I in very detail describe 17 different hikes in the park and around, including hikes: to Martial Glacier, Esmeralda Lagoon, Lago Roca, Guanaco trail, Pampa Alta, Laguna del Cominante, Waterfall Los Amigos, Mount Cortez, multiday trekking in Sierra Valdivieso Circuit, long Beagle Channel Trail, and finally, Southernmost multiday trekking Dientes de Navarino. I also give all the details for wild and paid camping, hostels, food stores, roads conditions, travel scenarios, public buses, prices for touristic services, paid tours, wildlife safaris, fishing, kayaking, At the end of the guide, I give detailed information what kind of wild animals and where you can meet in Tierra del Fuego land (Magellanic penguins, Gentoo penguins, King penguins, condors, huemul, guanaco, fox, sea lions, beavers) and their behavior. 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/landscape photographers on a mission.
