The closest commercial airports are in El Paso (185 miles) and Midland-Odessa (170 miles). Although you can count on roughly 2.5 to 3 hour drives from either, when driving from El Paso you'll lose an hour going from Mountain time (El Paso) to Central time (McDonald). For private aviation there are airstrips in Marfa and Alpine (both about 40 miles from the Observatory). Both have car rental services.
Where to stay
Fort Davis is the nearest town to the Observatory and boasts a number of hotels and motels as well as a number of B&Bs.
