Each year, a great wildebeest migration takes place in East Africa's vast plains, as millions of ungulates trek more than 600 miles in search of fresh grass. Thomson's gazelles, zebras, and other prey animals join with the wildebeests en masse, and predatory lions, hyenas, and jackals follow the herd as a promising food supply. Safari Ventures, named one of the World's Best Adventure Travel Companies by National Geographic in 2009, sends tour groups in four-by-four vehicles on a circular trek across the Serengeti plains in search of migrating wildebeests and other big game. The itinerary includes the following and is available on select dates:Days 1–2: Flights on Ethiopian Airlines depart from Washington-Dulles International Airport (IAD) and arrive at Tanzania's Kilimanjaro International Airport (JRO) the next day (after a stopover in Addis Ababa, Ethiopia). Upon arrival, visitors are transferred to the nearby Kia Lodge for an overnight stay. Mount Kilimanjaro, the tallest mountain in Africa at more than 19,000 feet, is visible in the distance on a clear day. Days 3–4: After breakfast, tour groups head to Lake Manyara National Park for the first of many game drives. There, zebras and buffalo rove the plains, and more than 400 bird species fly above. Blue monkeys, bushbucks, mongooses, and flamingos also comprise the area's native population. Visitors retreat for the night to Migunga Tented Camp. Days 5–7: After breakfast, tour groups enter Serengeti National Park, a UNESCO World Heritage Site they'll explore for the next three days. On the way to Serengeti, the caravan stops at a Masai village to learn about the local tribe's culture and heritage. Most of the time in the park is spent on game drives, searching for the wildebeest, elephants, giraffes, lions, and jackals. Guests stay overnight in Ikoma Tented Camp.Days 8–9: After a breakfast and one last morning game drive in Serengeti National Park, the safari heads toward the Ngorongoro Crater. Along the way, the tour makes a pit stop in Olduvai Gorge, an archaeological site where paleontologists discovered fossils that date back nearly two million years. Within the Ngorongoro Conservation Area, safari drivers seek out the big four animals: lions, elephants, leopards, and rhinoceros. Nightly accommodations are at Crater Forest Lodge. Days 10–11: On the final leg of the safari, the caravan makes the return trip, passing through the town of Mto wa Mbu. Here, safari-goers can stretch their legs and browse local markets. Later that evening, guests take a homeward-bound flight on Ethiopian Airlines from Kilimanjaro International Airport (JRO). View the FAQ page for more information. Pre-trip excursions to Mount Kilimanjaro and the beaches of Zanzibar are also available for an additional fee.
