The idea of a secret country is at once perplexing and terrifying, and makes people wonder who they're allied with and what they're trying to hide.
But their secret status typically just means the country is not yet officially recognized, and these young countries are eager to make a name for themselves.
The self-proclaimed country of Transnistria declared independence from Chisinau in 1990 and has decided to embrace that Communist country during the Cold War vibe- complete with statues of Lenin and hammer & sickle flags.
Transnistria isn't closed off to visitors, but if you want to visit you'll have to take a bus across the border from Moldova, and their KGB style police force may be less than welcoming...
So maybe you should head to sunny Somaliland instead?
Somaliland is an island of calm in the middle of Somalia's ongoing civil war, and even though this northwestern part of Somalia declared independence back in 1991 the Republic of Somaliland has yet to be officially recognized.
The young nation is currently considered the "No. 1 failed state according to the Fund for Peace’s Fragile States Index of 2016.", so Somaliland's future is uncertain at best despite 26 years of stability.
