Ostrander Lake is located in Yosemite National Park, approximately 10 miles (16 km) south of Yosemite Valley and 10 miles (16 km) east of the Badger Pass Ski Area. The lake is a popular destination for cross-country skiers during the winter. It is the primary source of Bridalveil Creek, which feeds Bridalveil Falls. The hike to Ostrander Lake is a long and strenuous 12.7 miles (20.4 km) roundtrip hike starting from the trailhead located just after Bridalveil Creek on the Glacier Point road. The hike begins with a fairly level path through an extensive burned over and regrowth area, with both shaded and sunny areas.
