Often lost in the shadow of nearby Mount Kilimanjaro, 4,566m-high Meru — Tanzania’s second-highest peak – also offers a highly scenic trek to the top. The ascent route starts in grassland and lush forest on the mountain’s lower slopes, rising up through picturesque glades and finishing with a dramatic and exhilarating walk along the knife edge of volcanic Meru’s crater rim. Meru is smaller than Kilimanjaro, and a trek can be done comfortably in four days, three nights. However, do not underestimate the mountain: its steepness, sheer drop-offs on the final ascent and the effects of altitude make it an almost equally challenging climb. Mount Meru is part of Arusha National Park, and all climbers must be accompanied by a park ranger, which can be arranged at the entry gate.
