Why you should climb Mount Meru before Kilimanjaro

2026-07-14 · Trekking

Four days on Tanzania's second mountain is the single most useful thing you can do for your Kilimanjaro summit chances.

The problem with Kilimanjaro

Almost everyone who fails on Kilimanjaro fails for the same reason: they gained height faster than their body could adjust. Fitness helps you enjoy the walking, but it does not protect you from altitude. Time does, and most itineraries are sold on price, which means they are sold short.

What Meru does

Mount Meru tops out at 4,566 m. That is higher than any camp on Kilimanjaro except Barafu, and you reach it on day three of a four-day trek. Your body responds by producing more red blood cells — a change that persists for two to three weeks. Start Kilimanjaro within that window and you begin the climb already adapted to an altitude that would otherwise take you five days to reach.

How much rest in between

Two days is the sweet spot. Less and you carry the fatigue of the first mountain onto the second; much more and the benefit begins to fade. Our eleven-day combination puts two full rest days in Arusha between the two climbs.

It is worth climbing anyway

Set the acclimatisation aside and Meru still earns its place. The summit ridge above the ash cone is more dramatic than anything on Kilimanjaro, you walk the first day with an armed ranger through genuine big-game country, and you will likely share the mountain with a handful of other people rather than a few hundred.
