try, TNCM(Princess Juliana Intl) to TFFJ(St Barthelemy), it is only 10 to 15 min.
And also, if you land rwy 10 you have to dive down to the runway over a hill, but be warned, you must download a certain file found on Avsim, otherwise landing and takeoff is literally impossible.
Search St barthelemy on avsim 2004 scenery, it fixes the positioning of the island so it is correct.
Landing is quite fun on rwy 10 but you might need some practice or you
will naturally dive from too high up and end up going off the end of the
runway into the water. 😂
P.S: make sure you use a STOL aircraft, because the runway is quite short at TFFJ, the BN-2 Islander is my fave.
