You push aside a tangled rope of vines, pressing through the maze of foliage, when at last you see them. Ten or 12 gorillas sit in a forest clearing, two more up in a tree. They stop munching for a moment to observe you, nonchalant. A few feet away, you spy the big silverback. Twice the size of the young females, he sits on massive haunches, stripping leaves from branches. He’s close enough to hold your gaze with his liquid brown eyes. Something primal, inexplicable, connects the two of you in that moment. The rest of the world slips away outside this rare encounter. On this riveting wildlife expedition, meet mountain gorillas at close range and observe a host of other primates, too.
