Largest golf course at an airport

Don Mueang International Airport in Bangkok, Thailand is home to an 18-hole golf course, which sits between its two main runways. Although fairly narrow by conventional standards, the golf course fills much of the gap between the two runways, which are 3,700 and 3,500 metres in length. The golf course belongs to the Royal Thai Air Force, whose 1st Air Division is based at Don Mueang International Airport. There is no separation between golfer and runway, merely a red light to warn when aircraft are about to land or take off.
