Why the three parks work together
They are genuinely different, not variations on a theme. The Virungas are cold, steep, bamboo-and-Hagenia forest at 2,500 metres. Akagera is warm savannah, lakes and papyrus swamp in the east. Nyungwe is dense Afromontane rainforest that has stood for millennia. A traveller who does all three has seen three ecosystems rather than one country three times.
Rwanda's Big Six is the neat framing: lion, leopard, rhino, elephant and buffalo in Akagera, and the mountain gorillas in Volcanoes National Park. Few itineraries anywhere deliver that in under two weeks of gentle driving.
