Mt. Kilimajaro and Mt. Kenya are the biggest and most adventurous sights of east africa.

Kilimanjaro is a volcano of complex structure and alkaline lavas situated at an intersection of fault lines. Shira was the first volcano of the group to become inactive, followed in turn by Mawensi and Kibo. The latter retains its caldera--1.5 miles in diameter and 600 feet deep--within which there are found successive inner cones and craters as well as fumaroles (holes or vents that emit gases).View More

The long-extinct volcano of Mount Kenya has been much denuded, and the highest peaks consist of the crystalline nepheline-syenite (a granular rock of alkalic feldspar, nepheline, and other minerals), which plugged the former vent. Around this core are gently dipping lavas, agglomerates, and tuffs. View More
