Nothing quite prepares you for the specific mix of anxiety and awe that comes before a gorilla trek.
It varies enormously by which gorilla family you're assigned and how far they've moved overnight — anywhere from thirty minutes to seven or eight hours of walking. Porters are available at every trailhead to support less mobile trekkers.
You get exactly one hour. Most people describe it as passing both instantly and completely differently from how they imagined it.
Buhoma has the gentlest terrain; Rushaga has the most habituated families; Ruhija is quieter and better for birders; Nkuringo is the most demanding but the most scenic.
