There are very few active volcanoes in Africa that are safe to explore (because they rarely pose a danger to human life). Mount Nyiragongo, a sensational landmark found in the Democratic Republic of Congo is one of them. It last erupted in 2002 and since then, it has been gentle. It stands at an elevation of 3,470 m (11,380 ft) above sea level. Its main crater area is about 2kms wide. Atop the crater floor at its summit lays a lake of bubbling magma that is surrounded by walls of earth and solid larva ash. It is roughly 600ft wide and 60ft high. 

As Mount Nyiragongo boils vigorously, it produces roaring waves and a bright fiery glow that lights up the scene at night. Its energy and latent danger showcases an impressive display of the power of nature. It such a moving spectacle, the type you would want to behold forever. Luckily, there are triangular shaped sleeping huts at the edge of crater rim where you can stay as you do so. They have spongy mattresses and pillows which provide suitable padding to sleep on. 

Ironically, the temperature at the top is very cold. This is because a cloud swirls around the rim of the crater. To this effect, sleeping bags are available for hire in case you need extra comfort.
