19. Virunga National Park - Democratic Republic of Congo
The Eastern part of the DRC is still a dangerous place to go with still ongoing guerrilla activity.
"Getting there requires a flight to Kigali, Rwanda, and a three-hour taxi ride."
"While a park spokeswoman said there have been no reports of unfriendly encounters between rebels and tourists, the eastern D.R.C. remains an unpredictable area that calls for sensible precautions."
If you want to see the mountain gorilla, just go to Rwanda. Very safe country, the Switzerland/Singapore of Africa. Or Uganda for even cheaper. I am not saying to only go to safe places, but avoiding active combat zones is easy to do.
Sad to see almost nothing in (non Northern) Africa. Great place to avoid the mobs.
EDIT: a few more points
36 - Tyrol, Austria
The Tyrol extends into Italian as south Tyrol, so if you are touring Italy, visit this region.
45 - Phnom Penh, Cambodia
I found it boring, and so did most visiting non-expats that I met. Most tourists simply visit the Killing Fields and prison, which is not mentioned.
