Avoid 12 things gorillas hate in Uganda distance, eye contact, sickness, and more. Essential safety and ethics for your trek.

Gorilla trekking in Uganda is an incredible wildlife experience, but it comes with serious responsibilities. These animals are wild, powerful, and have clear boundaries. They dislike certain human behaviors, and breaking their rules can lead to dangerous situations for you and serious harm for them. Mountain gorillas share 98% of our DNA, which makes them highly vulnerable to human diseases like the flu or a common cold. That is why park rules around distance, health, and behavior exist. Your trek is not just about taking photos; it is about being a respectful guest in their forest home. This guide lists 12 things gorillas hate, from getting too close to using flash photography. These rules protect both you and the gorillas. Following them ensures a safe, calm, and ethical encounter. The goal is to observe these animals in their natural state, not to disturb or stress them.


1. Getting Too Close

Gorillas strongly dislike it when people break their personal space. The rule is to keep a minimum distance of 7 meters, which is about 21 feet . This rule is not just for show; it is the most important safety rule on your trek. Getting closer than 7 meters puts you at risk of a charge and, more critically, risks passing human diseases to the gorillas. A study in Bwindi found that tourists spent 60% of their time within 3 meters of gorillas, breaking the guideline . This closeness stresses the animals, making them scratch themselves and change their normal social behavior. Your guide will make sure you stay back. Listen to them. It is for the gorillas' health and your own safety.


2. Making Direct Eye Contact

In the gorilla world, a direct stare is a challenge, especially for a silverback . They interpret this as aggression or a threat. If you lock eyes with a silverback, it might respond with a bluff charge to scare you off. The correct way to observe them is to look down or off to the side, keeping them in your peripheral vision. This shows you are not a threat and helps keep the encounter calm. By avoiding direct eye contact, you respect their social rules, letting the family relax and go about their normal activities like feeding and grooming without feeling cornered or challenged.


3. Using Flash Photography

A sudden bright flash of light is something gorillas find alarming and hostile . It can scare them, causing them to become agitated or even charge. This also ruins the experience for everyone by creating tension. Park rules strictly forbid the use of flash for this reason . To take good photos, adjust your camera’s settings for low light or use the natural light that filters through the forest canopy. Remember, the goal is to quietly observe their natural behavior, not to startle them with a sudden burst of light. Being prepared with the right camera settings makes you a respectful guest in their home.


4. Eating, Drinking, or Smoking Near Them

Gorillas are naturally curious, and the smell of food can attract them, which is dangerous . It can make them want to approach you, breaking the safe distance rule. For the gorillas, eating human food is unhealthy and can lead to dependency. Smoking is also forbidden because the smoke can irritate them and, more seriously, a dropped cigarette butt could start a fire in the dry forest. Park rules prohibit any eating, drinking, or smoking during the one hour you spend with the gorillas . Enjoy your snacks and water before you start the trek, and keep a safe distance from the animals.


5. Making Loud Noises and Sudden Moves

Gorillas are easily stressed by loud noises and jerky, sudden movements . The forest is their quiet home, and unexpected sounds or fast actions can make them feel threatened. This can make them agitated and disrupt their natural behavior. You are asked to speak in a low whisper, keep your phone on silent, and move slowly and deliberately . This calm approach allows the gorillas to stay relaxed. They will be more comfortable feeding, resting, or playing with their young, giving you a much better and more natural viewing experience.


6. Trekking While Sick

This might be the most serious mistake you can make. Mountain gorillas are genetically very similar to humans, making them highly vulnerable to human diseases like the flu, a cold, or even a cough . They have no immunity to these common illnesses. An infection that is mild for you could be deadly for a gorilla. Park rules strictly forbid anyone with a communicable disease from trekking . It is your responsibility to be honest about your health. If you feel unwell on the day of your trek, you must tell your guide. The gorillas' lives depend on you making this tough but ethical choice.


7. Trying to Touch Them

No matter how close they are or how safe they look, you must never, ever touch a gorilla . A gorilla might approach you out of curiosity, but that does not mean it wants to be petted. They are wild animals, and touching them is dangerous. More importantly, it risks transmitting diseases from your hands to them, which can be fatal. They also find touch from a stranger threatening. Keep your hands to yourself. The rule is to stay 7 meters away. If a gorilla does come closer, you should slowly back away to re-establish that safe distance .


8. Wearing Strong Scents

Gorillas have a powerful sense of smell. Wearing strong perfumes, colognes, or even heavily scented lotions and insect repellents can be very irritating and confusing to them . The strong, unnatural smell can agitate them and make the encounter stressful. For your trek, it is best to go scent-free. Use unscented deodorant and skip the perfumes. It is also a good idea to apply insect repellent at your lodge rather than immediately before the trek. This helps you avoid giving the gorillas a sensory overload, letting them treat you as a neutral presence rather than a smelly intruder.


9. Surrounding the Group

When you are with the gorillas, you must always stay together as a group and never surround the animals . If gorillas are approached from all sides, they can feel trapped and cornered, which triggers a strong defensive response. This is a quick way to make them feel threatened and aggressive. Your guide will position your group of up to eight people in one spot, out of the gorillas' way . By staying in a tight group, you show that you are a single unit and not a pack of predators surrounding them. This helps the gorillas feel secure and keeps everyone safe.


10. Making Unnecessary Noise While Tracking

This isn't about being loud near the gorillas, but while you are hiking through the forest to find them. Loud talking, snapping twigs, or other human noises can travel far and alert the gorillas to your presence long before you arrive. This can make them nervous and even cause them to move away, making your trek longer and harder. While on the trail, keep your voice low and be mindful of your footsteps. Let the forest sounds of birds and insects be the main soundtrack. This quieter approach lets you soak in the atmosphere and increases your chances of a smooth, calm sighting.


11. Wandering Off Alone or Breaking from the Group

You must always stay close to your trekking group and never wander off on your own . The rangers assign a maximum of eight people per gorilla family to minimize stress on the animals . When you break away or lag behind, you create unpredictable movement patterns that can confuse or alarm the gorillas. They might see you as a threat or something to watch closely, disrupting their natural behavior. Staying together as a tight unit shows the gorillas you are one non-threatening presence rather than multiple threats surrounding them . This rule also protects you. The forest is thick and easy to get lost in, and the rangers know the safest paths. Listen to your guide, keep your group in sight, and never go exploring on your own.


12. Littering or Leaving Any Trash Behind

Gorillas are naturally curious animals, and they might pick up or eat anything they find on the forest floor, including your trash . Dropping food wrappers, plastic bottles, or any waste is dangerous because it can harm them if swallowed or cause disease. It also ruins the clean habitat they live in. Park rules strictly ban littering, and you are expected to carry all your trash back out with you . Many operators also ask you to avoid single-use plastics for this reason. This rule is about respect for the gorillas and the forest. Keeping their home clean is a simple way to show responsibility. Pack out everything you pack in and use reusable water bottles to minimize waste.


Best time to trek gorillas in Rwanda

The best time to trek gorillas in Rwanda is during the dry seasons, which offer the most comfortable hiking conditions and easier trails. The long dry season runs from June to September, and the short dry season runs from December to February . During these months, trails are firmer and less muddy, making the trek less physically demanding, and the clearer skies provide better lighting for photography . However, these months are also peak travel periods, so you must book your gorilla permits and accommodation several months in advance . You can still trek during the rainy seasons from March to May and October to November . The trails will be slippery and more challenging, but you will find fewer crowds, lower prices, and lush, dramatic forest scenery perfect for photographers
