Street View Panoramas: main trailhead · service road trailhead
The red line marks the main Sentinel Dome trail, beginning at the green hikers towards the bottom of the map. The cyan line marks the Sentinel Dome service road, a shorter alternate route (about two thirds of a mile one way from trailhead to top of the dome).
The yellow line is the trail to Taft Point. Savvy hikers frequently combine Taft Point and Sentinel Dome into a single expedition, since they share a trailhead and since the Pohono Trail - the purple line on the map - provides a connector route with its own memorable view over the rim of Yosemite Valley.
The Taft Point/Sentinel Dome trailhead is only a few miles from Glacier Point itself; Glacier Point's boomerang-shaped parking lot is visible towards the top right of the map, and if you zoom in you can also see the cafeteria and much of the trail.
