Area 51 (Homey Airport / Groom Lake), a highly classified U.S. Air Force facility within the Nevada Test and Training Range, lies in southern Nevada's remote desert. Yosemite National Park sits in California's Sierra Nevada, ~200 miles (320 km) west by road.
Typical Driving Route: From the Area 51 vicinity (Rachel, NV on NV-375 "Extraterrestrial Highway") → US-6 west → US-95 north → NV-266 / CA-168 west over Montgomery Pass → US-395 north → CA-120 west (Tioga Pass, seasonal) or CA-108 (Sonora Pass) into Yosemite.

The journey crosses the Great Basin, White Mountains, and Sierra crest—starkly beautiful, geologically diverse, and lightly traveled.
