Anyone ready to participate with a maximum age of 16 and above must purchase a gorilla viewing permit in advance. The current cost for gorilla viewing permits in Uganda is $ 600 USD per person per trek, $ 450 USD low season (April, May & November) every year and in Rwanda was increased from $ 750 USD to $1500 USD per person per trek by Rwanda Development Board, plus in Congo is $400 USD per person per trek for one hour visit in a group of eight visitors.
We recommend you also hire a porter at an additional cost of $15 per trek, as they will help carry your day pack, assist you trekking when necessary, and it provides additional income to the local community.
