Lakes Nyos, Cameroon

Here’s another crater lake that looks outstanding from a distance but is actually a danger for humans. Located in Cameroon, Africa, Lake Nyos has formed years ago after an asteroid collided on its surface. The main thing that makes this lagoon stand out from the rest is how it sits on the Cameroon Volcanic Line, one of the country’s most active geological sites.

Truthfully, it’s positively forbidden even to consider swimming in the water as an earthquake could trigger an eruption and cause severe damage to the surroundings, like what happened back in August 1986. That tragic event should be enough to keep people at bay!
