A guided walk through a lava cave with 31 entrances and a large bat colony
Just outside Musanze town, close to the main road towards Rubavu, the ground opens into one of Rwanda's most unusual natural sights. The Musanze Cave runs for about two kilometres through layers of basalt laid down by lava from the Bisoke and Sabyinyo volcanoes. Its main entrance is a towering arch, and the roof has collapsed in so many places that the cave has 31 openings, sending beams of light into the darkness.
Visits are by guided tour only, along trails, stone steps and railings built when the site was developed for tourism. Helmets, boots and rain jackets are provided, and the chambers echo with the sound of a large colony of bats. It makes a good half-day outing on arrival in Musanze or on a rest day between gorilla and volcano treks.
The caves of the Musanze area formed as flowing lava cooled and hardened on the surface while molten rock continued to move beneath. Over centuries local people sheltered in them during times of war, and archaeologists working in caves near Musanze have found pottery, metal objects and bones, with one date suggesting occupation around the late first millennium AD.
The cave is also a place of grief. It was the site of a massacre during the 1994 Genocide against the Tutsi, and Visit Rwanda asks visitors to behave with respect. The Rwanda Development Board developed the site for tourism with walkways and safety measures, and it opened to visitors in 2013, with hundreds of local people employed in the work.
For residents of Musanze the cave is part of the town's history rather than only a tourist attraction. Some families initially saw the cave as a grave and were wary of visitors, and many now value the jobs and income the site provides. Guides are local, and visitors who listen to their stories and keep a quiet, respectful manner help preserve the dignity of the place.
The guided tour lasts about two and a half hours and follows paths and steps through the main chambers, with your guide explaining how the cave formed, how it has been used and the wildlife living inside. The ground can be wet and uneven and you will be walking in semi-darkness, so a reasonable level of mobility is needed; the site is not suitable for wheelchair users.
The visit combines easily with a walk or bike ride around Musanze, a trip to the twin lakes Burera and Ruhondo, or an afternoon in Kinigi after a morning trek.
As an underground attraction the cave can be visited year-round, and it is a useful option on rainy days. In the wet months of March to May and October to November, paths at the entrances can be muddy and dripping water is more noticeable inside, so the waterproofs and boots provided are welcome. The drier months of June to September and December to February make the approach easier.
