Mount Meru is Mount Kilimanjaro’s little sister, standing at 4,566m compared to 5,895m, but is still an impressive freestanding volcano, which makes a superb four day climb to the top. It last erupted in 1910 therefore can be classified as an active volcano. The first Mount Meru ascent was made by Dr. Fritz Jaeger, 1904. The town of Arusha lies at the base of Mount Meru Trekking, loads of trek companies do this trek. Wild animals are frequently found on this mountain therefore an armed ranger usually accompanies the trekkers.
