Redding sits at the north end of the Sacramento Valley, where the Sacramento River runs clear and wide and the Cascade foothills rise nearby. The Sundial Bridge, a glass decked pedestrian bridge that works as a sundial, spans the river at Turtle Bay Exploration Park, linking trails, gardens, and museum exhibits on both banks. Sacramento River Trail follows the water for miles, giving walkers and cyclists a green corridor through the city, while Shasta Dam and Whiskeytown Lake lie nearby for boating, fishing, and mountain views.
