Situated along the eastern border of the Democratic Republic of Congo, the Virunga National Park is a designated UNESCO World Heritage Site. It is one of the oldest national parks in Africa and features a biodiverse protected area inhabited by a plethora of weird and wonderful wildlife. It is home to at least a quarter of the world’s endangered mountain gorilla and also the unique Okapi 'zebra-giraffe'. The park stretches over 7500 square kilometres of unspoilt terrain characterised by dense forest, savanna, wetlands, lava fields, deep valleys, volcanoes, and the glaciated peaks of the Rwenzori Mountains. Popular activities include: mountain gorilla trekking, chimpanzee habituation and trekking experiences, guided nature walks through tropical rainforest, and hiking the Nyiragongo volcano to view the world’s largest lava lake.
