John Muir was known as the "Father of the National Parks." He loved and wrote about nature, helping to preserve many beautiful parts of the West, especially Yosemite National Park. Toddlers can explore with John to see the Sierra Mountains and giant Sequoia trees; they might catch sight of a mama bear and her cub, or see a beaver dam built high on a stream. Nurture the spark of a lifelong love of nature with Little Naturalists: The Adventures of John Muir.
