Yosemite National Park is open, including the valley, Highway 41 through Madera County, Fish Camp, Mariposa Grove and Glacier Point. The weather is cooling off for crisp fall evenings, and Tenaya Lodge at Yosemite, just minutes from the newly re-opened Mariposa Grove of Giant Sequoias, has tons of great fall activities to get you and your favorite four-legged friend outside.
