Situated along the border of Uganda and Kenya, Mount Elgon is the oldest and largest solitary volcano in East Africa and has one of largest intact calderas in the world. This extinct shield volcano is split by the Uganda/Kenya Border with a Mount Elgon National Park in both countries. It measures an impressive 80 kilometres in diameter and rises over 3000 metres above sea level. Mount Elgon is home to a variety of rare plants and abundant wildlife. The area also offers excellent climbing and walking along Koitobos, the highest peak on the Kenya side, reaching up to 4200 metres.
