10. Gustaf III Airport – San Bartolomé

Year of construction: 1984
Risk factors: Short runway, near the beach

This airport’s strange feature is that it only provides its services from 8:00 a.m. to 6:00 p.m. In addition, it can only be used by small airplanes of no more than 20 passengers, since its location would considerably complicate the take-off and landing of larger aircrafts.

The track, only 2,133 feet long, is located between a hill and a beach. This means that pilots must be very careful when they maneuver. And, tourists on the beach should also be careful; there are even signs that warn them not to sunbathe near the base of the track.
