There has been an energetic debate between the RGS, BMC and those involved in taking people up Kilimanjaro.They´ve been looking at the high incidence of altitude related illness on the mountain from climbing it too fast.Many operators organising trips make the ascent up the standard Marangu route in 5 days without pre-acclimitisation.The BMC recommends that individuals considering ascending Kilimanjaro be aware that that a longer ascent (10 days would be optimal, based on purely medical grounds) or pre-acclimatisation (e.g. on nearby Mt Meru) will significantly reduce risk levels and make the experience more enjoyable. In addition the choice of a route other than the heavily used Marangu will have significant environmental benefits. ( Source: BMC )
