Goma, Democratic Republic of Congo - Mount Nyiragongo towers over the city of Goma, in the east of the DRC. In 2012 and 2013, M23 rebels and Congolese army soldiers fought at the base of the mountain - which is an active volcano - and tens of thousands of displaced people camped out under its shadow.
Following the defeat of M23, the Democratic Forces for the Liberation of Rwanda (FDLR) moved into the area.
Since the end of the hostilities, rangers from the Virunga National Park have been clearing rebels from the volcano.
Now, Mount Nyiragongo is reopening to the public for the first time in more than two years, allowing visitors to climb to its summit and stare down into the world's largest lava lake. The lava lake is still active from an eruption in 2002, which wiped out at least 15 percent of Goma.
