(CNN) -- This week on Inside Africa: Beauty and danger in the great outdoors. A recent discovery in Congo boosts hopes for endangered gorillas, Kenyan rangers try to keep a tourist haven from becoming a poacher's paradise and a South African adventurer paddles toward a very distant goal.

Tourism takes a hit as violence rocks Kenya

Each year, about two million wildebeests migrate between the Serengeti in Tanzania and the Masai Mara in Kenya. The spectacle is usually a huge draw for visitors, but this year tourism is way down due to an outbreak of violence following Kenya's disputed presidential election. As David McKenzie explains, fewer tourists mean less funding for those charged with protecting the animals from poachers.

Saving a species

Even after the recent, stunning discovery of 125,000 Western Lowland gorillas in northern Congo, the endangered species still faces serious threats to its survival. The Dian Fossey fund is dedicated to saving gorillas. Jim Clancy met up with the organization's president at Zoo Atlanta.

Madagascar in a kayak

South African adventurer Riaan Manser first set out to make a name for himself two years ago by riding his bike around the entire continent of Africa. He chronicled his sometimes-terrifying experiences in a book, appropriately entitled, "Around Africa on my Bicycle." Now, he's trying to kayak around the island nation of Madagascar. Shortly before he left a few days ago, he talked to Jim Clancy about his trip and the motivation behind it.
