I never even thought about international. I am not sure what would work best for that area. I used to use google earth a long time ago to get an idea of different areas. Google has some things about an app called AllTrails that may work in that area. it is free, so may be worth a shot. You will likely need cell signal to use it though and that may be rough in remote areas.
@@OverlandCalling I also use Google Maps without the Internet, provided that I download the map in advance while connected to the Internet. Then I can use it without the Internet, but it is not as high quality as when connected to the Internet.
