Offers a 2-day climb and tour of Goma. Owner is a native of the region and very friendly, but it can take time to track him down. It's better bring your own equipment when trekking the volcano as the stuff Hakunamatata safaris provide is of low quality (e.g. leaking tents)
This volcano, famous for its lava lake, is a technically easy climb from the direction of Goma. A trip to the top should take ~6-8 hours, so most climbers spend the night at the top. The park was closed in May 2009 due to the rebel occupation but was reopened in March 2010; it closed again during the M23 siege of the city but it reopened on November 2014. The tour with the Virunga National Park costs USD$255 for internationals and USD$55 for Congolese and it includes the permit to the park as well as the lodging at the top of the volcano and guides.
