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.
