Leave camp just after dawn where you'll join researchers on a foray into the forest, arriving at the chimps' nesting spot just before they leave for a day of hunting and foraging, exploring the vines and romping through the undergrowth. Known as the primate capital of the world, Uganda and Kibale in particular, provides the chance for a once-in-a-lifetime chance to help habituate chimps who have often never encountered humans before. If it's intrepid, challenging and utterly magical you're after, this checks all the boxes. There's the choice to return home at noon or make it a full-day experience, where you'll get to see the chimpanzees construct their nests in the canopies. The most pleasant and least rainy time of year for this is between June and August, or December and March.
