What Do Silverback Gorillas Eat in the Wild? Your Guide & Trekking Plan
What do silverback gorillas eat to maintain a frame that stands up to 6 feet tall, spans several feet across, and weighs anywhere from 350 to 500 pounds? When you look at a fully grown male, it is incredibly easy to assume they are fierce, apex predators that hunt the dense jungles of equatorial Africa. Their massive canine teeth and sheer, raw muscle power look like they were built for the chase.
But a closer look reveals a completely different reality. These majestic, gentle giants are almost entirely vegetarian.
So, how many calories do they need to consume, and how does their specialized diet keep them fueled in some of the most rugged, high-altitude rainforests on Earth? Let’s dive deep into the fascinating culinary world of the silverback gorilla, followed by a complete 3-day itinerary from Kigali to see these incredible animals munching in their natural habitat.
The Core Diet: What Do Silverback Gorillas Eat?
To understand what do silverback gorillas eat, we have to look at their natural habitats. Because mountain gorillas (Gorilla beringei beringei) live in high-altitude cloud forests like Volcanoes National Park in Rwanda and Bwindi Impenetrable National Park in Uganda, fruit trees are incredibly scarce. As a result, these primates have evolved into highly specialized folivores—animals that primarily eat leaves, stems, and shoots.
According to long-term research data from conservationists, a mountain silverback gorilla’s diet breaks down into these primary components:
- Leaves, Shoots, and Stems (86%): This forms the absolute bulk of what they eat. They consume over 140 different plant species. Their absolute favorites include wild celery (Thysanolaena latifolia), stinging nettles (Urtica spp.), and thistles (Carduus spp.).
- Roots, Pith, and Tree Bark (7%): During drier months when tender green shoots are scarce, silverbacks use their immense strength to peel the bark off trees or dig up succulent tubers and roots for moisture and vital minerals.
- Flowers and Fruits (2% to 3%): While lowland gorillas farther west can have diets consisting of up to 70% fruit, mountain silverbacks rarely find fruit at elevations above 3,000 meters. When wild berries or figs do ripen, they are treated as highly prized delicacies.
- Insects and Invertebrates (1% to 2%): Silverbacks are not strictly vegan. They will occasionally break open a rotting log or a termite mound to snack on grubs, ants, and termites, giving them a quick boost of vitamin B12 and protein.
Quantity and Calories: How Much Do They Consume?
Knowing what do silverback gorillas eat is only half the story; the scale of their consumption is mind-boggling. Because a diet of leaves and fiber is incredibly low in caloric density, a silverback has to consume massive quantities of food just to survive.
An adult male silverback gorilla can eat up to 30 to 34 kilograms (66 to 75 pounds) of vegetation every single day.
To put that into perspective, that is the equivalent of eating roughly 60 to 70 heads of lettuce in a single 24-hour period. Because of this, silverbacks spend almost half of their daylight hours foraging, chewing, and migrating from one feeding zone to another.
Their large, round abdomens aren’t fat—they host an enlarged, specialized gastrointestinal tract. This complex digestive system uses specialized gut bacteria to ferment the massive amounts of fibrous plant matter via a process similar to “cud-like” digestion, breaking down cellulose into usable energy. They also get almost all of their water intake from the moisture trapped inside the plants they eat, meaning you will rarely ever see a wild gorilla drink directly from a stream or river.
Witnessing the Feast: A 3-Day Luxury Gorilla Trekking Safari from Kigali
Now that you know what do silverback gorillas eat, nothing compares to watching a 400-pound silverback gently peel a stinging nettle with his leathery fingers right in front of you.
Below is a meticulously planned, high-end 3-Day Gorilla Trekking Safari starting and ending in Kigali, Rwanda. This route takes you straight into Volcanoes National Park—the world-famous home of the mountain gorillas made legendary by researcher Dian Fossey.
Safari Overview
- Start/End: Kigali, Rwanda
- Destination: Volcanoes National Park (Musanze)
- Primary Focus: Mountain Gorilla Tracking & Rwandan Cultural Heritage
- Transport: 4×4 Luxury Safari Land Cruiser
Day-by-Day Itinerary
Day 1: Arrival in Kigali & Scenic Drive to Volcanoes National Park
Your private professional safari guide will pick you up from Kigali International Airport (KGL) or your hotel in Kigali. Before leaving the capital, you will embark on a moving and educational city tour, including a visit to the Kigali Genocide Memorial, which provides crucial historical context to Rwanda’s incredible journey of peace and reconciliation.
Following lunch in Kigali, you will hop into your 4×4 safari vehicle and begin the stunning 2.5-hour drive northwest toward Musanze. The winding roads showcase exactly why Rwanda is called the “Land of a Thousand Hills,” with views of terraced tea plantations and the towering, jagged volcanic peaks of the Virunga Mountains cutting into the sky. Arrive at your lodge in the evening for dinner and a briefing on the big day ahead.
Day 2: The Ultimate Gorilla Trekking Experience in Volcanoes National Park
This is the day you discover firsthand what do silverback gorillas eat. Wake up to an early breakfast before heading to the Kinigi Park Headquarters at 7:00 AM. Here, you will be assigned to a specific habituated gorilla family based on your physical fitness level and enjoy a traditional cup of Rwandan coffee while watching a brief cultural performance.
Accompanied by armed park rangers and trackers, you will hike through local farmland up to the stone park boundary wall, entering the misty, primordial rainforest. The trek can take anywhere from 1 to 5 hours depending on where the gorillas nested the previous night.
Once found, you will spend exactly 1 hour standing just meters away from the troop. You will watch the playful infants tumble, the mothers groom each other, and the massive silverback strip bamboo or snap wild celery stalks with effortless power. Return to the lodge for a celebratory lunch. In the afternoon, visit the Ellen DeGeneres Campus of the Dian Fossey Gorilla Fund to see state-of-the-art interactive exhibits mapping gorilla conservation history.
Day 3: Golden Monkey Tracking & Return to Kigali
Enjoy another early breakfast before heading back to Kinigi Headquarters, this time to track the rare, playful, and endangered Golden Monkeys (Cercopithecus kandti). These striking, canopy-dwelling primates live exclusively in the bamboo forests at the base of the volcanoes. Unlike the calm, methodical movement of gorillas, golden monkeys are high-energy acrobats, leaping through the bamboo branches and flashing their rich orange-gold coats.
Following your trek, return to the lodge to check out, pack, and have lunch. Your guide will drive you back to Kigali, stopping at local artisan markets along the way for souvenir shopping. Drop-off will be at your preferred hotel or back to the airport for your departure flight.
