Q:  What is the closest airport to McKinney Roughs?

A:  McKinney Roughs is located about 15 miles east of Austin-Bergstrom International Airport (ABIA).  ABIA is by far the closest airport to the park.  If you prefer, flying into the San Antonio International Airport is also a possibility, but you will have to rent a car and drive about 1 1/2 hours to the park.  Houston (Intercontinental or Hobby) and Dallas (DFW or Love Field) are bigger hub cities with more flights (and possibly cheaper flights) but they will involve a 3+ hour drive to the park.
