Trips to see gorillas are always guided by experienced guides who are accompanied by rangers armed with AK 47 machine guns hence you are safe deep in the forest. Guides will lead a small group of people into the forest to find a group of habituated gorillas even though gorillas are still wild animals but overall the trekking experience is safe.
Once you reach gorillas it’s very exciting to watch adults feeding, grooming and resting as the young ones play and swing over trees in an amusing way.
Even though gorillas have been habituated, sometimes when humans interfere with their daily activities they can charge just like humans do when annoyed. However it should never scare you to trek because guides will always tell what to do in case it happens. Some of the scaring behaviors a male silverback might do include beating the chest or making alerting sounds. In such a circumstance, your guide will tell you to turn away or crouch down or step backwards at a slow pace and once you do this gorillas will realize that you are not a threat to them and things will be normal.
