Lots of random patches of dirt (and grass and even some asphalt) listed in this thread so far, clearly accessed by light aircraft and helicopters.
(someone will come along shortly with an offshore oil rig, or top of a city skyscraper I’m sure). Given that the thread title is visited rather than flown into/out of, I’d nominate Kill Devil Hills, Kitty Hawk, Nth Carolina, USA.
But the title does also say ‘airport’ and much of what has already been posted are fields, and/or air strips; even airfields, for those tin shack sites. Maybe
@Mattg could put some bounds on what he considers an ‘airport’ to be? Or maybe not…
I personally think an ‘aircraft operating site’ only really qualifies as an
airport if it has RPT operations being conducted; the ‘port’ bit of the word indicating passengers routinely coming and going rather than an ad hoc charter site or something else ‘special purpose’. And with that out of the way I’ll nominate:
- GAN, funnily enough Gan Island in the Maldives. Flown into and out of via UL A320.
- IUE, which is the airport on Niue, flown into and out of onboard NZ A320.
- KRP, Karup with short lived Danish airline Cimber Sterling, via ATR72.
