You can click on the boxes to have the list of the countries for each large geographical region, probably the easiest and the best overview

or click on the pictures below to have the countries of each sub-region.

We have countries or territories still on our travel list and also some countries we don't have any intention to visit (Afghanistan, Pakistan, North Korea, and many african countries with civil, religious wars or terrorism...) because it's too dangerous or risky at the moment.
