From the junction of the Big Balanced Rock Trail and Heart of Rocks Loop, the Sarah Deming Trail heads generally east through the maze of rocks. The trail descends into Sarah Deming Canyon, and to get there, you'll get to squeeze through pathways through the rocks. This makes the run much more interesting than simply working your way through the forest.
Once runners leave the interesting pathways behind, the trail descends further into Sarah Deming Canyon, then hugs the edge of Rhyolite Canyon to meet up with the Upper Rhyolite Canyon Trail and Lower Rhyolite Canyon Trail. As the trail approaches the junction, views begin to open up of the formations in the canyon below, as well as up to Sugarloaf Mountain.
At 1.6 miles from its beginning, the Sarah Deming Trail ends at the Rhyolite Trail, with the Upper Rhyolite Trail turning right (this can be used to return to the Echo Canyon Parking Area via the Echo Canyon Trail) and the Lower Rhyolite Trail turning left (this can be used to return to the visitor center).
