Though not as well known as Yosemite’s famous Half Dome, at 4,150 feet high a climb up Sentinel Dome offers some incredible 360 degree views of the national park. The 2.6 mile hike up is well-marked with signs and is easy to follow. From the gently-rounded top you can see the whole of Yosemite Valley, including Yosemite Falls, Half Dome, El Capitan, and the Sierra Nevada Mountains. The trail is mostly flat, except for the granite slope to the summit.
Sentinel Dome first became known for the lone Jeffrey Pine tree that grew from its peak. The tree is no longer there, but was well-documented by photographer Ansel Adams. The dome is a sight in itself, but the real rewards are the views from atop. It’s a good alternative to the often crowded viewpoints of Glacier Point, and is particularly scenic during the sunset hours.
To access Sentinel Dome, park at the Sentinel Dome/Taft Point lot on the north side of Glacier Point Road. From there the trail is marked to the summit (it’s the same as the Taft Point trailhead.) It is about a 40 minute drive up from the valley floor.
