Landing in Tegucigalpa (MHTG) is very scenic and also one of the most challenging approaches in the world. Another scenic and difficult approach is Hong Kong’s Kai Tak airport (VHXX) which is no longer in use but you can fly in the game.
Scenic landings that are somewhat challenging but really beautiful: Quito (SEQM), Mexico City (MMMX) and Bogota (SKBO).
Scenic approaches that are not too challenging: Lima (SPJC) and Santiago (SCEL).
PS: I suggest looking for the STAR charts when creating your flight plan. Most of the airports I mentioned have tall mountains surrounding them, so you cannot make straight in approaches into most of them.
