It is located 70 km west of Mount Kilimanjaro, sometimes treated as an acclimatization before an attempt on Kilimanjaro and although the summit is over a kilometer lower, the climb can be just as rewarding with spectacular scenery.
The moods of Mount Meru varies wildly in the winter months, snow briefly dusts the summit while for the reminder of the year it is sunbathed. The Crater wall of the Mountain was ruptured by a series of explosions 250,000 years ago. The eastern wall of the crater was blown away sending lava, mud, rocks and water cascading across the sanya plains almost as far as Moshi in the foothills of Kilimanjaro.
The Mountain`s vegetation zones are similar to Kilimanjaro`s though the high altitude glaciers and ice fields are absent. Evergreen forest begins at around 1800m which is moist, cool and thick at first, then thins as you rise. The higher forest, including giant bamboo thickets (up to 12m tall), offers an ideal habitat for small duiker antelopes and primates, notably blue monkeys, black and white colobus monkeys which are often seen by climbers. The forest disappears at around 2900m, giving way to floral meadows where you might spot buffalo, giraffe or warthog. The meadows are followed by a zone of giant lobelia and groundsel and finally above the last of the trees at 3400m, bleak alpine desert where the only sound apart from your breathing is the wind and cries of the white necked ravens.
