Visitors' eyes are continually drawn to this remarkable granite formation that tops out at more than 4,700 feet above the valley floor. Despite its name, the dome is actually about three-quarters intact. You can hike to the top of Half Dome on an 8.5-mile (one-way) trail whose last 400 feet must be ascended while holding onto a steel cable. Permits are required (and checked on the trail), and available only by lottery. Call 877/444–6777 or visit www.recreation.gov well in advance of your trip for details. Back down in the valley, see Half Dome reflected in the Merced River by heading to Sentinel Bridge just before sundown. The brilliant orange light on Half Dome is a stunning sight.
