From the Big Five to silverbacked Mountain Gorillas, wildlife is the draw on this 16-day safari through Kenya, Tanzania and Rwanda where game drives and mountain treks reward you with once-in-a-lifetime encounters with animals, both endemic and endangered. All departures are small groups, limited to 24 guests.

On this 17-day safari we range through 34 degrees of latitude and four countries, but, most engagingly and contrastingly, we experience the diverse excitements of Cape Town's urban pizzazz, the watery colossus of Victoria Falls, and the wondrous game lands of the Serengeti-Maasai Mara ecosystem, where the wandering rains compel the planet's most momentous movement of big, interesting mammals.

Journey through narrow straits of jaw-dropping majesty and gaze at vast glaciers of incandescent blue on this trip of a lifetime. A two-hour flight from Punta Arenas brings you to Antarctica's doorstep where you'll board your comfortable cruise ship. While sea conditions determine the itinerary, our ships call on remarkable places such as Deception Island — a volcanic caldera that we can sail into — and Paradise Bay, a favorite spot for Zodiac cruising to see fantastical iceberg sculptures. Few places on Earth make a deeper or more lasting impression than Antarctica.
