Glacier Point, an overlook with a commanding view of Yosemite Valley, Half Dome, Yosemite Falls, and Yosemite’s high country, is accessible by car from approximately late May through October/November. From mid-December through March, cross-country skiers can experience this view after skiing 10.5 miles.
You can drive to the overlook via State Highway 41 or you can take the Glacier Point Tour. This is also a good starting or finishing point for some of Yosemite’s most popular trails, including the Four Mile Trail and the Panorama Trail.
The best time to visit is early spring or fall before the road closes for the season. In the summer, it can be too popular, especially in the middle of the day.
