The red line shows the central trail, about half a mile long, that leads across the meadow and the Tuolumne River footbridge to the vicinity of Parsons Lodge and the soda springs. The yellow line shows the little warren of trails winding around the lodge and soda springs themselves.
The green line marks the trail (the first part of it is actually a road) that leads from the Dog Lake / Lembert Dome trailheads to the center, more or less, of Tuolumne Meadows. There's parking available at both the red and green trailheads.
The purple line shows a trail that heads west from the footbridge along the north bank of the Tuolumne River. It eventually merges with a road and arrives at the world's most beguiling sewage pond.
The brownish line follows the approximate route of the Pothole Dome trail, which tracks along the western edge of Tuolumne Meadows. There's a small parking area at the railhead.
Tuolumne Meadows is the hub of the Tioga Road area of Yosemite. Along the south side of the road, facing the meadow, are a visitor center, a campground, a cafeteria/convenience store, and a gas station/sporting goods store. There are also several trails radiating out from the meadow. The two trails slipping off the south edge of the map are the trails to Cathedral Lakes and Elizabeth Lake, respectively. The trail to Lembert Dome, Dog Lake, and Young Lakes heads north along the right side of the map. The trail that begins near Parsons Lodge (around the yellow trail) and passes north of the Pothole Dome trail is on its way to Glen Aulin. The visible right fork of that trail eventually turns northeast and merges with the Young Lakes trail.
