If you’re planning a gorilla trekking or chimpanzee trekking safari in East Africa, you may be wondering: What is the difference between mountain gorillas and chimpanzees?
Although both species are great apes and share over 98% of their DNA with humans, they are remarkably different in appearance, behavior, habitat, intelligence, and social structure.
Mountain gorillas are known for their enormous size, gentle nature, and family-oriented lifestyle, while chimpanzees are smaller, highly intelligent, energetic, and incredibly social.
Whether you’re visiting Uganda, Rwanda, or the Democratic Republic of Congo, understanding these fascinating differences will help you appreciate each primate encounter even more.
Mountain Gorillas vs Chimpanzees at a Glance
| Feature | Mountain Gorilla | Chimpanzee |
|---|---|---|
Scientific Name | Gorilla beringei beringei | Pan troglodytes |
Average Weight | 135 – 220 kg | 40 – 70 kg |
Habitat | High-altitude mountain forests | Tropical rainforests and woodlands |
Diet | Mainly herbivorous | Omnivorous |
Social Group | Gorilla family led by a Silverback | Large communities with multiple dominant males |
Lifespan | 35 – 40 years | 40 – 50 years |
Trekking Experience | Slower and calmer | Active and energetic |
1. Physical Appearance
One of the easiest ways to distinguish mountain gorillas from chimpanzees is by their size.
Mountain gorillas are the largest living primates on Earth. Adult males, known as silverbacks, can weigh over 200 kilograms and have broad chests, muscular arms, and thick black fur adapted to cold mountain climates.
Chimpanzees are much smaller, slimmer, and lighter. They have longer arms relative to their body size, larger ears, and less body hair around the face.
Mountain Gorilla Features
- Large muscular body
- Thick black fur
- Broad chest
- Small ears
- Adult males develop a silver back
Chimpanzee Features
- Smaller body
- Longer arms
- Prominent ears
- Dark face
- More agile build

Chimpanzees are much smaller, slimmer, and lighter. They have longer arms relative to their body size, larger ears, and less body hair around the face.
2. Intelligence
Chimpanzees are considered the most intelligent great apes after humans.
They are famous for:
- Making tools
- Solving problems
- Hunting cooperatively
- Using sticks to catch termites
- Learning from one another
Mountain gorillas are also highly intelligent but tend to rely more on social learning and communication rather than tool use.
3. Strength
Mountain gorillas are incredibly powerful.
A fully grown silverback possesses enormous upper-body strength that allows him to protect his family from predators and rival males.
Chimpanzees are also exceptionally strong for their size and are estimated to be much stronger than humans of similar weight. However, they rely more on speed, agility, and teamwork than brute force.
4. Habitat
Although both species live in forests, their habitats differ significantly.
Mountain Gorillas
Mountain gorillas live in high-altitude forests between 2,200 and 4,300 meters above sea level.
They are found only in:
- Bwindi Impenetrable National Park (Uganda)
- Mgahinga Gorilla National Park (Uganda)
- Volcanoes National Park (Rwanda)
- Virunga National Park (DR Congo)
Chimpanzees
Chimpanzees inhabit lower-altitude tropical rainforests, woodland savannahs, and forest edges.
Popular chimpanzee trekking destinations include:
- Kibale Forest National Park
- Budongo Forest
- Kyambura Gorge
- Nyungwe Forest National Park
- Mahale Mountains National Park
5. Social Structure
Mountain gorillas live in stable family groups led by a dominant silverback.
A typical gorilla family includes:
- One silverback
- Adult females
- Juveniles
- Infants
The silverback protects the group, settles conflicts, and determines where the family feeds and rests.
Chimpanzees, on the other hand, live in much larger communities that may contain over 100 individuals. Leadership changes more frequently, and males compete for dominance.
6. Behavior
Mountain gorillas are generally calm, peaceful, and gentle animals. Most visitors are surprised by how relaxed gorillas appear during trekking experiences. Chimpanzees are far more energetic.
They:
- Climb trees rapidly
- Swing through branches
- Vocalize loudly
- Interact constantly
- Display playful and sometimes aggressive behavior
Watching chimpanzees is often a fast-paced adventure compared to the quiet experience of observing gorillas.
7. Diet
Mountain gorillas are primarily herbivores.
Their diet includes:
- Leaves
- Bamboo shoots
- Wild celery
- Roots
- Bark
- Fruits
Chimpanzees have a more varied diet.
Besides fruits and plants, they also eat:
- Insects
- Ants
- Termites
- Honey
- Bird eggs
- Small mammals
This makes chimpanzees omnivores.
8. Movement
Both gorillas and chimpanzees use knuckle-walking when moving on the ground. Chimpanzees are much faster climbers and spend more time in trees.
Mountain gorillas spend most of their lives on the ground because of their large body size.
9. Reproduction
Female mountain gorillas have a gestation period of about 8.5 months, while chimpanzees have a gestation period of approximately 8 months
Both species usually give birth to one infant at a time and provide extensive parental care.
Young gorillas remain close to their mothers for several years, while young chimpanzees learn complex social behaviors within their communities.
Gorilla Trekking vs Chimpanzee Trekking
Many travelers ask which experience is better.

- Close encounters with gorilla families
- Less movement once found
- Emotional wildlife experience
Chimpanzee Trekking
