The closest commercial airport is the Mammoth Lakes/Yosemite Airport (MMH), located on California Highway 395 just south of Mammoth Lakes.

From the Mammoth Lakes/Yosemite Airport drive north on CA Highway 395 to the Mammoth Lakes/Highway 203 exit. Turn left at the stop sign onto State Route 203 into Mammoth Lakes.
The next closest airport is the Reno/Tahoe International Airport (RNO). From Reno, drive south on U.S. Highway 395 for approximately 3 hours (170 miles) to State Route 203.
From U.S. Highway 395, drive 10 miles west on S.R. 203 to Minaret Vista and then another 8 miles on a paved, steep mountain road. Please note that this road is single lane for approximately 3 miles.
