Lonely Planet Rocky Mountains & Pacific Northwest's National Parks: Discover the Great Outdoor's (National Parks Guide)

Not as detailed as I hoped and expected for a book dedicated to specific parks. Especially for Yellowstone and Grand Teton I would rather get the Lonely Planet dedicated to these two parks, as it contains more useful information and recommended hikes. Or get the one with all national parks as it has the same amount of info than this book. In my opinion this one isn't worth buying.
