Day 2: Explore sections of one of the longest "Lava Tube" caves in the world - Leviathan. These caves, which world-wide, are relatively rare, are thought to have been formed when molten lava, of specific type and viscosity flowed down a slope of a specific angle. The surface layer cooled and solidified, but the lower part, still molten, continued to flow on down. At this point, somewhere up the hillside a collapse of the surface crust occurred through which air enters, and so a tube evacuated itself just below the surface. Afternoon and the evening spent down in the caves looking at some of the fascinating formations found therein - Sink holes, lava ropes, stalagmites and stalactites, benches and of course the secondary, water formed features.

Day 3: Early morning departure by road for the top of the Chyulu Hills. Superb walking country with gently undulating grasslands, interspersed with dense patches of forest. Possibility of viewing herds of eland and other antelope, giraffe, zebra and wildebeest with slightly lesser chance to see elephant, lion and buffalo and the other game that live in the area. Probable views of Kilimanjaro just 50 km away. Night somewhere along the crest. Probably cool and windy with low cloud in the early morning.
