Bwindi Impenetrable National Park
Gorilla trekking, once-in-a-lifetime trips, fit walkers
Bwindi holds roughly half the mountain gorillas left on earth. You walk into thick, steep, ancient forest with a ranger and a tracker, sometimes for an hour and sometimes for six, and then spend one hour with a habituated family at a few metres' distance. People who have done every safari there is still describe it as the best hour of their lives.
