If you are an experienced hiker looking for the challenge of a lifetime, Kilimanjaro’s Umbwe Route could be the perfect choice for your Kilimanjaro expedition. Short, steep, and strenuous in parts, the Umbwe Route jumps from 1,600m to 3,900m above sea-level in just 48-hours, and so it is perhaps no surprise that it is commonly referred to as the most difficult route on Africa’s highest mountain.
