During the winter, skiers are rewarded only after a 10.5 cross-country tour; during the summer, hikers can choose from the misleadingly named Four Mile Trail (it's actually closer to five miles long), the nearly nine mile Panorama Trail or, for the truly ambitious, a combination of the two trails, to reach the promontory.
However, if you lack the time, desire or stamina to climb the nearly 3,200 feet (975 meters) above the valley floor, consider the four-hour Glacier Point Tour, which departs daily from Yosemite Lodge.
The Glacier Point Tours require reservations, but can be made from any Tour & Activity Desk. Tours depart at 8:30am, 10am and 1:30pm daily from May through October. Cost ranges from $23 for a child to $41 for an adult; children under five years of age are free. One-way tickets are available if you decide to ride up and hike back down.
