OL KARIEN GORGE
A visit to Ol Karien Gorge is referred by many visitors as a spectacular trip. The scenery is prehistoric. Huge mountains, canyons and spectacular rock formations dominate the wide meandering valleys. Geologically it is an amazing site with the great canyon slicing through the earth-the gorge is naturally inviting!
Olkarien gorge is one of spectacular landform in the eastern edge of the Gol Mountains in the Serengeti eco-system. The main attraction of the gorge is the colonies of the highest flying birds ‘the Ruppell’s Griffon Vultures’. These highly social vultures of the Serengeti, makes large nests of sticks and have been breeding their chicks here for thousands of years.
When thermal currents start to develop enough lift in the mornings, The Ruppel’s Griffon Vultures are seen slowly leaving the roost and continue soaring around the gorge. The Ruppel’s Vultures flies to the West for up to 90 miles searching for the great Serengeti herds and stays in the air for almost seven hours patrolling for animal carcasses.
The gorge provides a unique and safe nesting for almost a hundred bird species. On mid day, the gorge is also used by the Maasai warriors who herd their animals to drink water at the wells dug below. Visitors to this mystical gorge experience a classic example of natural interaction between man and wildlife in a natural setting
