The Gibraltar airport is one of the high-detail airports in Flight Simulator 2020 and the Rock of Gibraltar is right next to it and also looks great.

The flight includes a brief trip across the strait, giving you a little bit of over-water time before arriving in Spain where you can get a nice look at some windmills on the hills.

Continuing on you'll cross the bay where there are a bunch of cruise ships with The Rock of Gibraltar right in front of you on the other side. You may want to take a circle around it once before landing if. The airport looks pretty nice and you get a cool view from the ground.
