North Korea and the DRC both seem to contain gorgeous landscapes that aren't very well documented. Would love to be able to backpack through the 'wilderness' of either one of those countries. Northern North Korea seems particularly beautiful from the limited photos available - lots of blue lakes and mountains.
El Salvador is one of the safest countries in the Americas, safer than the USA and at the level of countries like Canada (by homicide rate)! Amazing country
