I am only listing countries that I have actually stayed in, not merely passed through.
The pages listed below should not be treated as complete travel guides; for any of these places, especially the bigger ones, there are tons of more things worth seeing/doing. This is just a personal archive (which is being updated) of things I want to remember.
