The highway begins at I-15 in the community of Baker, the last town travelers from the Greater Los Angeles area or the Las Vegas Valley see before making their trek across Death Valley. SR 127 travels through the town of Baker as Death Valley Road before turning slightly northwest and traveling along the edge of Silver Lake, a dry lake. The road parallels Salt Creek and Silurian Lake as it crosses the Valjean Valley. SR 127 soon runs along the southeastern edge of Death Valley National Park and cuts through the mountains as it is entering Inyo County.
