Niger
Annual visitors: 157,000.
Niger is the perfect example of a country that has so much to offer but no one to share it with. In Niger, you can find stunning desert views, gorgeous mountains, and little towns that perfectly sum-up the culture of the Nigeriens. For all its beauty, the country lacks visitors mostly because of the fact that, at the moment, it is quite dangerous for foreigners. One day, perhaps, things will change and the world will be opened up to a beautiful country.
San Marino is a mountainous microstate surrounded by north-central Italy.
Not much to see, it's more an extension of swisszerland, very disappointing to visit.
Also NIGERIA doesn't sound like a safe plan either
Niger (#3), Burkino Faso (#4), Timor-Leste (#12) and Sierra Leone (#14) are war zones, with rival factions fighting continuously. No one goes there unless they want to get abducted or shot.
Anguilla (#15) is still recovering from 2018 hurricane damage and remains uninhabitable.
No one is visiting Montserrat until they dig the airport out from under about 200 feet of lava. So you go there, there's no food, no water, and nowhere to stay. Great vacation spot!
New Caledonia (#5) and the Solomon Islands (#17) don't want tourists and the natives are openly hostile toward them. Much of the area doesn't have any drinkable fresh water, yet malaria is rampant. Perfect spot for a nice relaxing getaway.
Who writes these garbage articles? Seriously ... I know you don't get much on the internet, but that's pretty shabby.
