Many travelers have been discussing and giving reports on gorilla trekking difficulty and others have been asking questions of how tough is gorilla trekking in Uganda and Rwanda n different platforms like trip advisor and lonely planet but I have some detailed information below.
Some of the clients tell stories that Gorilla trekking in Uganda is tough because of the hikes to high elevations and others call his a life time experience because moving to and from the forest to trek mountain gorillas is another kind of incredible experience while others that are defeated take it to be an exercise of the day, so each traveler explains Gorilla trekking in their own way.
Now if you have booked your Gorilla trekking safari in Uganda or Rwanda and you have all the service and Gorilla permit confirmed for particular dates, you should worry no more about how tough/ difficult it will be when you enter the forest especially Bwindi as Gorilla trekking activity offers experience and what suits the visitors interests and special requests. You will not be allocated to a distant/long trek when you are not physically fit, all age blackest are catered for and always a group with old clients is given a slow pace and easiest gorilla family to trek.
Charging of mountain Gorillas/silver back, Bwindi forest habits a lot of wildlife like elephants, buffalo, and other primates, sometimes as you follow the trails to where the mountain Gorillas are on that particular day, there is a possibility of meeting such animals on your way and these animals can charge because they are not like savannah wildlife that are used to presence of human beings, another scenario is when the wild mountain Gorillas meet the habituated gorillas and fight like hours/ a day before you the them, you may find these gorillas when they have charged, these gorillas can always back t you but the rangers guides are always accompanied by armed men that if the situation goes beyond normal, always can scare shoot as they get safe custody for the clients.
Gorilla trekking as an activity involves hiking into different topography and dense forest of Bwindi impenetrable forest, and for this reason, actually some of the mountain Gorillas habit in high altitude of 2000 to 3000 and this when most of the clients starts getting difficulties and others even below this, also Bwindi forest is a tropical rain forest where by it can rain at any time of the day of course the rains wet the terrain but this does not stop the activity to take place, so this is where the trek becomes tough but others call it an experience of life.
Booking accommodation in a trekking sector that is different from where you will be trekking gorillas, for example, you book accommodation in Ruhija and secure a Gorilla permit for Rushaga,or accommodation at a distant place that need a 4hours drive to park offices. This mostly happens with clients who prefer to travel alone without using a tour operator, since availability of Gorilla permits sometimes becomes crazy, clients end up buying gorilla permits of any sector shout considering the accommodation they booked, so end up getting stranded on ground the day of gorilla trekking as they need to travel for long hours and early start which at times makes gorilla trekking difficulty in Uganda. We always advise you to use a tour operator like great adventures Uganda to organize for you a Gorilla trekking safari in Uganda or Rwanda
