Just judging by your title I would assume that you have either been to Utila or know someone who has. The old airstrip at Utila seemed fairly dangerous to me. The landings had to be made very precise or you may end up in the water at the other end. Likewise on takeoff, not enough power, then into the water again. Granted the water there is shallow but would not be fun. The new airport with the steep approach over the trees is not much better but at least it is paved to allow better control. As far as most dangerous I am not too sure, but Utila is on my list as one.
Yes,i would say the airport in honduras or La Aurora Intl. in Guatemala where a Taca 767 ran off the runway when it was coming in too fast right after a tropical storm passed by. It happened in the mid 90's and one passenger in the aircraft happened to have a camera at the time of the incident and filmed the disaster. Luckily there were no casualties.
Merida, Venezuela is quite something. It lies in a valley between high Andes peaks, is a short strip on a mesa, a signifcant downhill slope on landing, and most difficult, lies right in the hear of the city.
Although, i do not believe there have been seriosu accidents there. Up until several years ago I was amazed but Avensa flew 727s in there. The runway and setup do not look capable of handling it, obviously it could. That has all changed and all movements are STOL ATRs and Dash's.
AA777DFW is correct. The Honduras and the GUA airports are one of the most challenging. GUA one and only runway is about the length of the LGA rwys and yet is built in middle of the cities with tall building on one side of the airport.
There are many smaller airports that could easily be the "most dangerous" airport so it might be better if we narrowed the category to most dangerous airport with regular scheduled services from a 737/A318 upwards. In Europe I think the award must go to Funchal/Madeira – take a look at the runaway
MOL on SRB's latest attack at BA: "It's like a little Chihuahua barking at a dying Labrador. Nobody cares."
You´d better not look at the images of the MS Flight Simulator; some times they got the ground altitudes of airports wrong with respect to the scenery around it, hence the big craters you sometimes see...
I would suggest Lord Howe Island, off the coast of NSW. The runway itself it straightforward, but it lies between two large hills. If the wind is over 15kts, the turbulance can become quite severe and be beyond the capacity for most small planes.
The nearest alternate is 400NM away, on the Australian mainland.
