Venturing into Uganda's Impenetrable Forest will surely get your heart rate up. Inside the shadowed deep, you'll embark on a gorilla safari that will give you the chance to see Africa's mountain gorillas up close. First, you'll join a group in Uganda's coastal town of Entebbe to catch a plane to Kibale Forest National Park. For the next 11 days, you'll hike, trek and ride around Uganda's forests and plains while watching chimpanzees, gorillas, elephants and lions in their natural environment. You'll have the chance to ride across the lake-dotted savannahs in four-wheel-drive vehicles and track gorillas on foot up to altitudes of 8,500 feet (2.6 kilometers) in the Bwindi Impenetrable Forest. While on the trip, you'll have a chance to stay in everything from the national parks' lodges to a tent camp in Bwindi. All the while, you'll be as close as possible to the "gentle giants" that you have come so far to see [source: Wilderness Travel].
