These journeys are in a category of their own. Extra special destinations that deserve extra special thought and planning; luxury touches, and soul-stirring experiences. We’re talking about a million wildebeest moving as one across the plains of the Serengeti. Standing on the deck of an Antarctic expedition ship as you glide past towering glaciers in search of a blue whale. Coming face to face with a family of mountain gorillas in the rainforests of Rwanda. Trekking to Buddhist monasteries among soaring Himalayan peaks. We’re not saying that you only have to take these journeys once, but we put them together as if you are—once-in-a-lifetime journeys should be perfect, after all.
