Nyamulagira reaches a height of 3,058 meters on the western part of the East African Rift. Basaltic lava flows from the volcano have covered approximately 1,500 square kilometers in the North Kivu Province since 1900.
The Smithsonian Global Volcanism Program states that Nyamulagira is Africa’s most active volcano and that it has had more than 35 eruptions since 1880.
The volcano’s caldera is about 2 kilometers in diameter, and the broad summit lava fields consist of thin basalt flows that move quickly and accumulate over time, spreading from the center in many directions.
During the 2010 eruption, lava flows reached 20 kilometers from the summit crater.
Despite the fact that Nyamulagira has produced more lava than any other volcano in Africa, it is still one of the least visited and least documented volcanoes in East Africa.
Nyamulagira Volcano at a Glance: Key Facts

Nyamulagira is a shield volcano, meaning its shape comes from centuries of thin, fast-moving lava spreading outward from the summit in all directions.
The result is a wide, gently sloping profile built up layer by layer over thousands of years. The lava here flows easily because of its chemical composition, which is why the hardened lava fields around the base now cover roughly 1,500 square kilometers. You will walk across sections of this ground during the early stages of the trek.
Nyamulagira is prone to eruptions and emits flowing lava and gas plumes from its main crater, and at times from cracks that run down its sides.
During the eruption that occurred between 2011 and 2012, a lava lake formed in the crater and stayed there for several months before draining off.
This left a deep hole at the summit, and it is now the main source of the steam and sulfur gas that you will see coming from the rim.
While Nyamulagira is active, it emits a large amount of sulfur dioxide. In order to give warnings about possible eruptions, the Goma Volcano Observatory keeps a close watch on earthquakes and gas levels.
Nyamulagira is located in Virunga National Park, a site recognized by UNESCO as a World Heritage Site since 1979, and the park covers 7,800 square kilometers in eastern Democratic Republic of the Congo.
Park authorities control access to the volcano and, in collaboration with the observatory, decide each week whether treks can be carried out.
How to Get to Nyamulagira Volcano
Most international tourists fly into Kigali International Airport in Rwanda, located about 160 kilometers east of Gisenyi, a border town.
You can then hire a private four-wheel drive for the four-hour journey along the RN4 road to the border and complete customs clearance at the Grande Barrière border post in Goma, which is open every day from 6:00 to 18:00.
Ethiopian Airlines and similar airlines offer direct flights to Goma International Airport, located about 3 kilometers from the city center.
The tourism office of Virunga National Park helps you complete border formalities and organizes transfers by vehicle from either the airport or the border post, ensuring local transport regulations are followed.
When traveling from Goma to the headquarters of Rumangabo Park, you must cover a distance of about 40 kilometers by going north along Route Nationale 2.
The trip in a four-wheel-drive vehicle with high clearance over rough, unpaved roads will take roughly two hours.
Armed park rangers always accompany official tourist convoys that leave the city.
The final stage takes place at the designated locations. Upon arriving in the western section of the park, you will stop at the ranger posts to receive your briefings and to check your equipment with your expedition team.
Park staff organize all transfers by vehicle to the trailhead and stay in radio contact with the monitoring base in Goma throughout the journey.
A typical trek to Nyamulagira lasts from three to four days and starts at the Rumangabo headquarters.
Most groups go on a round trip covering 40 to 55 kilometers. The trek begins at an altitude of around 1,070 meters and climbs to the summit at 3,058 meters, so the elevation gain is about 1,988 meters.
Hiking days will last from six to nine hours as you go through extensive areas of basalt which have hardened over a period of more than a century as a result of volcanic eruptions; since there are generally no marked trails, the guides in Virunga National Park will choose a new route each day considering the age of the lava, the stability of the ground, and the current level of gas activity.
Above 2,400 meters, hiking becomes more difficult because of loose volcanic rock, sharp rock edges, and lower oxygen levels.
Night temperatures at the high camps often drop below 5°C, so use a sleeping bag rated for at least 0°C when you spend nights in tents.
For this journey, you will need to spend one night, as most hikers find it too difficult to make it to the two-kilometer-wide summit caldera within a single day; from the edge you can see active fumaroles, recent lava flows, and, as the Goma Volcano Observatory states, fresh molten rock if the summit is active.
Because sulfur gas is a primary concern near the crater, guides bring portable gas detectors to determine how close your group can get to the active vents.
To be prepared, pack high-energy food, carry at least three liters of water each day, and get fitter before the trek.
Best Time to Visit
When you plan the Nyamulagira trek, consider three things: the volcano’s eruption cycle, whether Virunga National Park is open, and the local rainfall pattern. Weather alone doesn’t decide whether the trek can go ahead; for instance, the trek will not be possible in April even if it is dry because the park may be closed due to an eruption or security issues in the north.
Volcanic activity occurs over geological timescales and is therefore unaffected by the seasons; Nyamulagira has erupted in almost every month of the year, and at any time lava or high gas levels can lead to trail closures.
We recommend checking the Smithsonian Global Volcanism Program activity feed about 60 days before your trip to see the latest conditions.
Regarding tourism operations, the park has been suspended and reactivated several times since 2018; these decisions are based on armed group activity in North Kivu, not weather conditions.
Verify the current operational status directly with the Virunga National Park tourism office at least 30 days before you leave.
After checking volcanic activity and park access, check the weather conditions.
The eastern part of the DRC has two dry periods and two wet periods each year. Between June and September, the conditions are most favorable because less than 50 millimeters of rainfall falls each month and the summit is visible most days.
From December to February, there is a shorter dry season with about 75 millimeters of rain per month and good morning visibility above 2,400 meters.
In the Virunga region, the wet seasons, which occur from March to May and from October to November, see more than 200 millimeters of rainfall each month.
The wet clay soils found below 1,800 meters make hiking slower and more tiring. If you hike during the wet season, add an extra day to your schedule in case of weather delays. Costs and Booking
If you want to visit Nyamulagira, you should purchase a park permit from the official Virunga National Park booking website.
The permit costs 300 USD per trekker and includes your daily park entry fee and the required armed ranger escort team.
Once you have booked, you can apply for a single-entry tourist visa; it costs 105 USD and takes about 14 days to process.
You’ll also have to pay additional fees for support staff and to rent basic equipment at the Rumangabo Park headquarters.
It costs 24 USD per day to hire a porter for up to 15 kilograms of equipment, and such porters are very helpful on the difficult basalt ground.
A gear package, including a sleeping bag and a tent, costs 100 USD per person for the entire climb.
Make your reservation as early as possible, as park regulations require you to complete your permit application at least 60 days before your trip to allow time for security checks.
To reserve a place in the daily vehicle convoys that leave Goma at 9:00 every morning, tour operators require full payment in advance.
To take part in the trek, you must have emergency medical evacuation insurance with coverage of at least 100,000 USD. You can reschedule your trip if security problems force you to change your plans, provided you do so within twelve months of the original booking.
