In winter the Mariposa Grove Road is not plowed and instead its open for skiers and snowshoers to explore the snow covered gigantic sequoias. Mariposa Grove is one of 75 groves that is home to some of the largest living organisms. The road meanders through the forest and makes a lollipop loop past some of the more famous trees of the grove, such as, the Fallen Monarch and the California Tunnel Tree. Check with Yosemite National Park for information on road closures and more specific dates on when this trail is open for winter activities. Restrooms are available at the fee station just before the parking lot for the trailhead.
