Sangmélima, Cameroon

This sleepy town of 80,036 on the Lobo River is not for the faint of heart. The bushmeat trade is rampant, with locals openly selling meat from endangered species like chimpanzees and gorillas. Authorities have done little to curb this practice, which has even been linked to Ebola outbreaks in the area.

Getting around is a logistical nightmare. While a new 321.5-kilometer road has connected Sangmélima to Ouésso, the $354 million price tag suggests the bureaucracy is a persistent headache. Relying on the underdeveloped 65-kilometer road to Bikoula is no picnic either.

If you can stomach the wild bushmeat culture and navigate the bureaucratic hurdles, Sangmélima may appeal to the most adventurous expats. But for most, this gritty town on the Lobo River is best avoided.
