Gorillas at Bwindi Impenetrable National Park.
A Guide to Gorilla Behavior, Conservation, and Trekking in East Africa
The mountain gorillas of Bwindi Impenetrable National Park are among the world’s most fascinating and endangered primates. Spending time with these gentle giants in their natural habitat is one of the most powerful wildlife encounters on earth—a rare experience that connects visitors to a species that shares 97% of its DNA with humans.
Mountain Gorillas at a Glance
Mountain gorillas are the largest of the great apes and once roamed widely across the forests of Central Africa. Today, just over 1,000 individuals remain in the wild. They live in two main populations:
- Bwindi Impenetrable National Park in Uganda – home to more than half of the world’s remaining mountain gorillas
- The Virunga Massif – spanning Uganda’s Mgahinga Gorilla National Park, Rwanda’s Volcanoes National Park, and DR Congo’s Virunga National Park
Thanks to strict conservation efforts, gorilla numbers have slowly increased—but they are still classified as endangered and require continuous protection.
Gorilla Behaviour and Lifestyle
How Gorillas Feed
Mountain gorillas are herbivores and spend about 30% of their day feeding, another 30% moving and foraging, and the remaining time resting. Their diet consists of bamboo shoots, wild celery, giant thistles, roots, and leaves—plants rich in water, which means gorillas rarely need to drink.
A dominant male silverback can consume over 30 kilograms of vegetation per day.
How Gorillas Live
Gorillas live in stable family groups led by a dominant adult male known as a silverback. A typical group has:
- 1 – 2 silverbacks
- Several adult females
- Young males (blackbacks)
- Juveniles and infants
- Most groups range between 10 and 15 individuals, but some can exceed 25. Strong social bonds exist, and hierarchy is determined by age, strength, and breeding rights.
Gorillas are peaceful primates. However, when leadership is challenged, male confrontations can occur. These often involve displays of strength—beating the chest, charging, and roaring—but physical fights are rare. When a new silverback takes over a group, he may kill all infants to assert dominance and start his own genetic line.
Communication Among Gorillas
Gorillas communicate using facial expressions, gestures, and over 20 different vocal sounds. Key communication forms include:
- Barks and roars – used by silverbacks to issue warnings
- Grunts – signals of reassurance or bonding
- Chest beating – a display of dominance or intimidation
- Playful vocalizations – among juveniles and infants
Gorillas are highly expressive and capable of emotional depth, which is why their interactions often feel familiar to human observers.
Biology and Life Cycle
- Adult male weight: up to 200 kg (440 lbs)
- Female weight: about half that size
- Sexual maturity: 8–15 years for males; around 8 years for females
- Gestation period: 8.5 months
- Infant dependency: stays with the mother continuously for first 6 months
Young gorillas become more independent around age three, although social relationships—especially with the silverback—remain strong. Silverbacks often adopt orphaned infants, a unique behavior not commonly seen in other primate species.
Mountain gorillas differ from lowland gorillas by having thicker, longer fur suited to their colder high-altitude environment. Gorillas in Bwindi are slightly less shaggy than those in the Virungas because they live at a lower elevation.
Where to See and Trek Mountain Gorillas
1. Bwindi Impenetrable National Park – Uganda
Home to over half of the world’s remaining mountain gorillas and recognized as a UNESCO World Heritage Site. Bwindi offers dense rainforest trekking with a high chance of close encounters. Although the terrain can be steep, the reward is extraordinary and intimate viewing.
2. Mgahinga Gorilla National Park – Uganda
Part of the Virunga Volcanoes. One habituated gorilla family is available for tracking, though they sometimes cross into Rwanda or Congo, making availability unpredictable. Treks are usually scenic and less strenuous than Bwindi.
3. Volcanoes National Park – Rwanda
One of the most popular and accessible gorilla trekking destinations. Terrain is more open, offering clearer views. This is where primatologist Dian Fossey conducted her famous research, memorialized in Gorillas in the Mist.
Booking Gorilla Permits
Uganda
- Permit cost: USD 700 per person (was USD 600 until June 2021)
- Available permits per day: approx. 136
- Total habituated families: 18 across Bwindi & Mgahinga
- How to book: Through the Uganda Wildlife Authority (UWA) or a trusted tour operator such as Terrain Safaris

Rwanda
- Permit cost: USD 1,500 per person
