Mt. Meru (4,566m.) is the second highest mountain in Tanzania and a very underrated mountain climb because of it’s close proximity to Kilimanjaro. It is a horseshoe-shaped volcanic crater with a spectacularly narrow ridge and superb all round views. The cliffs of the inner wall below the summit are over 1500 m. high, and inside the caldera is a subsidiary peak called the Ash Cone (3,670 m.) that last erupted only 100 years ago. There is an immense variety of tree and plant life, adding considerably to the interest of the trek.
