Looking to discover Kenya's most beautiful volcanic landscapes? Do you love a challenge and want to add new summits to your climbing achievements? We present the main volcanoes of Kenya to discover during a trekking expedition or mountaineering adventure.
1. Mount Kenya
Located in the heart of the country, 16 km south of the equator and 150 km from Nairobi, Mount Kenya rises to an altitude of 5,199 meters. It is Kenya's highest volcanic mountain and Africa's second-highest peak after Kilimanjaro.
A dormant stratovolcano formed roughly 3 million years ago with the opening of the East African Rift, the mountain was once blanketed by a substantial ice cap that eventually eroded, creating steep slopes and around ten glaciers. Its highest peaks are Batian (5,199 m), Nelion (5,188 m), and Point Lenana (4,985 m).
Offering spectacular landscapes and a rich ecosystem, Mount Kenya has enabled the creation of a national park and biosphere reserve, both designated as UNESCO World Heritage sites. Within the park, numerous animal species can be observed including: elephants, black rhinoceros, buffalo, leopards, hyrax, the world's largest population of Grevy's zebras, eastern bongo antelope, and countless bird species (Ayres' hawk-eagle, Abyssinian owl, white-rumped swift, white-bellied swift, and more).
Mount Kenya is also home to numerous Kenyan tribes whose beliefs are deeply connected to the mountain. Among the ethnic groups living at the foot and around Mount Kenya are the Maasai, Kikuyu, Ameru, Merus, and Embu peoples.
Climbing Mount Kenya:
Beyond offering the chance for wildlife safaris, Mount Kenya is a premier destination for trekking and mountaineering enthusiasts.
While the summits of Batian and Nelion require solid rock climbing expertise, it's possible to choose a route accessible to beginner trekkers via Point Lenana, considered the world's highest via ferrata. Note that ascending Mount Kenya can take between 3 and 7 days of walking depending on the chosen route.
2. Mount Longonot
Located in the famous Great Rift Valley, southeast of Lake Naivasha, Mount Longonot is a stratovolcano reaching 2,776 meters in elevation. It last erupted in the 1860s. More recently, in 2006, active magmatic systems were detected beneath the mountain.
Derived from the Maasai word "Oloonong'ot," meaning "mountain of crested ridges," Mount Longonot certainly lives up to its name. It is characterized by a caldera 12 km long and 8 km wide, topped by another crater measuring 1.8 km in diameter. The latter is covered with a thick forest of dense vegetation.
From the crater's rim, you can enjoy a spectacular view of the crater itself, Lake Naivasha, the Great Rift Valley,Hell's Gate reserve, and the Olkaria geothermal power plant.
Located within Mount Longonot National Park, this volcano offers numerous hiking trails to visitors. While trekking, it's not uncommon to encounter wild animals including elephants, gazelles, zebras, giraffes, and a multitude of birds.
Hiking Mount Longonot:
It's possible to climb Mount Longonot and circle its caldera. Plan for 1 to 2 hours of walking to reach the summit. Given the steep slopes, good fitness is advisable for the expedition. Once at the top, you can walk around the crater on the volcano's flanks. Allow approximately 3 hours for the full circuit.
3. Menengai Crater
Located in the Great Rift Valley, Menengai is a shield volcano standing 2,278 meters high. As a reminder, a shield volcano is characterized by effusive eruptions producing fluid lava flows. Formed approximately 200,000 years ago, the volcano experienced its last eruption around 6050 BCE.
Menengai is renowned for hosting Kenya's largest crater and Africa's second-largest after Ngorongoro in Tanzania. This crater spans 10 km in diameter and offers unique landscapes: lava flows, rust-red cliffs, vegetation, and more. From the crater's rim, you enjoy breathtaking views ofLake Nakuru andLake Bogoria. Surrounded by lush forest, the crater is home to some wild animals including Kirk's dik-dik and the black-faced vervet monkey.
Menengai Crater is the subject of numerous legends. Meaning "corpse" in the African Maa dialect, it's sometimes called "the house of demons." Indeed, stories tell of many people who have vanished within the crater. It's also said that the steam jets rising from its depths carry the souls of Maasai warriors to paradise.
Today, the crater is the subject of a geothermal energy production project.
Exploring and Hiking Menengai Crater:
Several hiking options are available to explore Menengai Crater. You can reach the viewpoint at the caldera's highest point by following an 8 km hiking trail from the town of Nakuru. This route can also be completed by motorized vehicle.
Once at the viewpoint, the more adventurous can undertake a hike down into the crater. This trail descends into the crater, makes a loop, and climbs back to the viewpoint. Allow 3 to 4 hours for the round trip. Note that the ascent is steep and may prove difficult if you lack training.
4. Mount Suswa
Mount Suswa is a shield volcano in the Great Rift Valley, situated between the towns of Narok andNairobi. At 2,356 meters altitude, it features a double crater. The inner crater, 5 km in diameter, is covered with forest, while the outer crater, approximately 10 km across, is home to theMaasai people who have established their settlements there.
Mount Suswa's ecosystem harbors exceptional flora including giant fig trees, as well as wild animals such as baboons, rock hyraxes, antelopes, zebras, hyenas, snakes, and numerous bird species.
Beyond being an excellent trekking destination, Mount Suswa is an ideal spot for caving enthusiasts. The site features a network of underground caves carved millennia ago by surging rivers of lava. You can explore them, ideally with a guide. Note that there's a cave containing rock paintings, another harboring an impressive bat colony, and one serving as a refuge for baboons nicknamed "the Parliament of Baboons."
Exploring Mount Suswa:
You can hike to Mount Suswa's summit from the inner crater's edge (where you can park your vehicle). The 10 km route typically takes about 4 hours of walking. You can also circuit the inner crater on a 22 km trail. Allow approximately 7 hours of walking depending on your fitness level.
5. Ol Doinyo Eburru Volcano
Ol Doinyo Eburru is a volcano part of an active volcanic complex in the Great Rift Valley. Among the other volcanoes in the group are Mount Suswa, Mount Longonot, Olkaria, Mount Elmenteita, and Menengai volcano. Located northwest of Lake Naivasha, Ol Doinyo Eburru peaks at 2,856 meters altitude.
Formed in various stages over time, Ol Doinyo Eburru today appears as an eroded ridge. In total, the volcanic complex covers 470 km². Among the landscapes encountered are rhyolitic domes, fumaroles escaping from cinder cones, picturesque ridges, and approximately fifty craters distributed along the complex's fault line.
The hiking trails leading to one of its summits (Eburru Hill and West Hill) wind visitors through the magnificent Eburru Forest, home to countless bird species and 40 mammal species including the mountain bongo, an endangered antelope species, baboons, colobus monkeys, buffalo, and dik-diks. The area also features waterfalls and numerous springs.
Like Menengai, Ol Doinyo Eburru is exploited for geothermal energy.
Exploring Ol Doinyo Eburru Volcano:
Two hiking trails lead to Ol Doinyo Eburru's summit: the East trail (also called the waterfall trail) and the West trail. Both span approximately 20 kilometers and require about 6 to 8 hours of walking.
Frequently asked questions
Kenya's highest volcano is Mount Kenya, which peaks at 5,199 meters altitude with its Batian summit. It is also Africa's second-highest mountain, after Kilimanjaro in Tanzania.
Not necessarily. While the summits of Batian (5,199 m) and Nelion (5,188 m) require technical rock climbing skills, Point Lenana (4,985 m) is accessible to beginner trekkers via the via ferrata, considered the world's highest. The complete ascent lasts between 3 and 7 days depending on the chosen route.
Most of the presented volcanoes are dormant or extinct. Mount Longonot last erupted in the 1860s, with active magmatic systems detected in 2006. Ol Doinyo Eburru still exhibits active fumaroles. Mount Kenya is a stratovolcano considered dormant for several million years.
The best periods for hiking in Kenya correspond to the dry seasons: January to March and July to October. These months offer more stable weather, less muddy trails, and better visibility from the summits. Avoid the heavy rains (April-May) and light rains (November).
Absolutely. Several volcanoes are integrated within national parks or reserves hosting diverse wildlife. Mount Kenya particularly offers the chance to observe elephants, leopards, black rhinoceros, and the world's largest population of Grevy's zebras. Mount Longonot, within its national park, also allows you to encounter giraffes, gazelles, and elephants during hikes.
Mount Longonot and Mount Suswa are most accessible from Nairobi. Mount Longonot, located roughly 90 km from the capital in the Great Rift Valley, can be reached in less than 2 hours by road. Menengai Crater, near Nakuru, is also well served. Mount Kenya, 150 km from Nairobi, requires more travel time but remains a premier destination.
