4-Day Mount Meru Trek

The 4-day Mount Meru trek in brief

The 4-day Mount Meru trek climbs Tanzania's second-highest mountain, 4,566 m (14,980 ft), inside Arusha National Park. You walk with an armed ranger through wildlife country on day one, sleep in park huts at Miriakamba (2,514 m) and Saddle (3,570 m), and reach Socialist Peak at sunrise on day three after a night climb along the crater rim. It is a demanding, rewarding climb in its own right, and the best acclimatization trek you can do before Kilimanjaro.

• Start and finish: Arusha, via Momella Gate
• Huts: Miriakamba Hut (2 nights), Saddle Hut (1 night)
• Summit: Socialist Peak, 4,566 m (14,980 ft), on day 3
• Hardest day: day 3, about 10 to 14 hours including the descent
• Best months: June to October and December to February

Why climb Mount Meru

Meru is a dormant volcano whose eastern wall collapsed long ago, leaving a horseshoe-shaped crater with a younger Ash Cone inside it. The summit ridge runs along that crater rim, and walking it at dawn, with the crater falling away on one side and Kilimanjaro rising about 70 km (43 miles) to the east, is one of the great mountain views in Africa.

It is also unusually varied for a four-day trek. The first day is effectively a walking safari: the lower slopes are open grassland and forest with giraffe, buffalo and colobus monkeys, which is why every group walks with an armed park ranger. Above that you climb through montane forest and giant heather into bare volcanic rock. And because Meru is far quieter than Kilimanjaro, the huts and trails rarely feel crowded.

Who it suits, and who it doesn't

Mount Meru is a good choice for:

• Kilimanjaro climbers who want to acclimatize first. See the section below.
• Fit hikers who want a high summit in four days without the length or cost of Kilimanjaro.
• Travellers who would rather sleep in huts than tents.
• Anyone who wants wildlife and mountains in one trip.

It is not the right choice if:

• You are uneasy on narrow ridges. The summit ridge is exposed in places. It is not technical, but it needs a steady head.
• You have never hiked a long day. Summit day is 10 to 14 hours of walking. Build up with long training hikes first.
• You want the highest summit. That is Kilimanjaro; our Kilimanjaro routes page compares all six.

Meru as Kilimanjaro acclimatization

Altitude is what stops most people on Kilimanjaro, and the best defence is time spent at intermediate altitude before the summit push. Meru gives you that: you sleep at 3,570 m on night two and climb to 4,566 m on day three, then come back down. If you rest two or three days in Arusha or Moshi and then start a Kilimanjaro route, your body has already begun to adapt.

Pair Meru with a gradual route rather than the fastest one. The 7-day Lemosho route is our usual recommendation. Our Kilimanjaro planning guide covers altitude sickness in detail, and the Kilimanjaro and safari guide explains how to sequence a longer trip.

The summit night on Mount Meru

Your guide wakes you around midnight to 1 a.m. at Saddle Hut. After tea you climb by headlamp, steadily at first, to Rhino Point, then along the crater rim. Sections of the ridge are narrow, with loose ash and rock underfoot, and your guide and ranger set a careful pace. Most climbers reach Socialist Peak around sunrise, after roughly four to five hours.

It is cold at the top. Temperatures near the summit can be below freezing, around −5 to −10°C (23 to 14°F) with wind chill, so climb in every warm layer, with gloves, a warm hat and a headlamp with spare batteries. After photos you descend to Saddle Hut for breakfast and a rest, then continue all the way down to Miriakamba. Trekking poles are a big help on the descent.

Best months to climb Meru

Meru's climbing seasons match Kilimanjaro's:

• June to October: the main dry season, with the most reliable weather and clearest summit mornings. Cold nights.
• December to February: the second dry window, warmer and often very clear.
• March to May: the long rains, heaviest in April. Trails are muddy and views often lost in cloud.
• November: the short rains, usually afternoon showers.

What the huts and crew are like

Meru is a hut route. Miriakamba and Saddle huts are run by the national park and have shared rooms with bunks and mattresses, plus a dining area. They are basic but dry; bring a warm sleeping bag rated for below-freezing nights. Water for washing is cold.

Your crew is a lead guide, an assistant guide, a cook and porters, plus the park's armed ranger, who stays with the group for the whole climb. The number of porters depends on group size. Meals are hearty and cooked fresh at the huts.

What's included

All Arusha National Park fees and rescue fees; three nights in mountain huts; your guide team, cook and porters; all meals on the mountain and drinking water; the armed park ranger; transfers between Arusha and Momella Gate; and crampons and walking poles if you need them. You bring your own sleeping bag and personal gear, and tips for the crew and hotels in Arusha are extra. Our Tanzania safari cost guide explains how park fees work.

What to pack for Mount Meru

You need less gear than for Kilimanjaro, but summit night is just as cold. The essentials:

• Footwear: broken-in waterproof hiking boots with good grip, plus camp shoes for the huts.
• Layers: a base layer, a fleece, an insulated jacket and a waterproof shell, with warm trousers for summit night.
• Head and hands: a warm hat, a sun hat, warm gloves and liner gloves.
• Sleeping bag: rated for below-freezing nights at Saddle Hut.
• Headlamp with spare batteries, trekking poles, sunglasses and sunscreen.
• Water: bottles or a hydration bladder for at least 3 litres; the crew boils or treats water at the huts.

Rental gear is available in Arusha if you are travelling light. Our Kilimanjaro planning guide has a fuller gear list that works for Meru too.

Safety on the mountain

• Acclimatization: report headache, nausea or breathlessness to your guide early. Worsening symptoms mean going down.
• Ridge safety: stay behind your guide on the summit ridge and stop to look at the views, not while walking.
• Wildlife: stay with the ranger on the lower slopes, especially around buffalo.
• Weather: it can be cold and wet at any time of year; pack waterproofs.
• Insurance: make sure your policy covers trekking to 4,600 m (15,100 ft) and evacuation.
• Health: talk to your doctor about altitude medication and travel vaccinations; see our vaccinations and health guide.

Make it a longer trip

Meru starts and ends in Arusha, which makes it easy to pair with a safari. After the climb, the 3-Day Tarangire, Manyara and Ngorongoro is a restful follow-on, and the 7-Day Classic covers the whole northern circuit. If you only have a day, our Arusha National Park day trip visits the lower slopes and lakes.
