Alice brings us through the seasons and places of California?s Sierra Nevada mountains. Starting in spring in Sequoia National Park to see the world's largest trees, then transitioning to summer in the eastern sierras to hike to alpine lakes and summit the tallest mountain in the lower 48 states. Fall brings us to Mammoth Lakes where we explore some of the best alpine lakes under the fall colors and winter brings us to Yosemite National Park, where snow has transformed the park's peaks and valleys to a winter wonderland.
