These falls are very near Foz do Iguacu airport which is included in the World Update XIX (Brazil, Guyana, Suriname & French Guiana); it’s well made freeware on the flightsim.to site, & the vapour around the falls is active which is a nice touch: Itaipu Binacional and Iguaçu Falls (is it ok to show links to freeware? - community managers feel free to edit if necessary)
I went there to see the new Iguacu handcrafted airport which is very nice, plus it’s a very short flight from Rio
It’s supposedly the same game, but the terrain quality is awful for me. I used to have very nice terrain textures. Now, due to quality issues, I’ve stopped including them here.
