Overview

About Mbulu

Mbulu is a highland town at around 1,700 metres in northern Tanzania, sitting in cool, green farming country between Karatu and Lake Eyasi.

It is the heartland of the Iraqw, a Cushitic-speaking people distinct from their Bantu and Nilotic neighbours, and the surrounding hills are terraced and intensively cultivated in a pattern quite unlike anywhere else on the northern circuit.

The town itself is small and functional, serving a farming district that produces wheat, maize, beans and dairy on volcanic soils at an altitude that keeps the climate mild year-round.

Very few visitors come here, and there is little tourism infrastructure. Mbulu suits travellers with their own vehicle exploring the highlands between Karatu and Lake Eyasi rather than anyone making a dedicated journey.

People and culture

People and culture

The Iraqw are the defining community here, and their language belongs to the Afroasiatic family, unrelated to Swahili or Maa, making this pocket of Tanzania linguistically unusual.

Traditional Iraqw homesteads, known as tembe, were built partly below ground level with earth roofs, a form adapted to both climate and defence, and some survive in the surrounding countryside.

Terraced hillside farming here is among the most intensive in northern Tanzania, and the Iraqw have cultivated these slopes for centuries using systems that have attracted considerable study from agricultural researchers.

Cultural visits are informal and arranged locally rather than through any organised programme, which means they depend heavily on finding the right guide, usually through accommodation in Karatu rather than in Mbulu itself.

Rain falls in two seasons, the long rains from March to May peaking in April and short rains through November. Annual rainfall is around 900 millimetres, which combined with volcanic soils accounts for the district's agricultural productivity.

June to August is the coldest period, dropping to around 9°C at night, and visitors arriving from the Rift Valley floor below notice the difference immediately.

The roads into Mbulu are unsealed in places and deteriorate during the rains, which is the main practical constraint on visiting. A 4×4 is advisable outside the dry months.

The higher ground around the town catches noticeably more rain than the Rift Valley floor below, and it is that additional moisture, combined with volcanic soil, which sustains the intensive terraced farming that defines the whole district.

Best months
Jan–Feb, Jun–Dec

Mbulu is visited by very few travellers, and its seasons matter mainly for road access into the highlands.

June to October is dry and clear, with the firmest roads and the most comfortable conditions for walking in the surrounding farmland. Nights are cold, dropping to around 9°C in June and July.

December to February is warm and largely dry, and the hills are green without being saturated, which makes it a pleasant window for driving through the district.

March to May brings the long rains, when the unsealed approach roads deteriorate considerably and a 4×4 becomes necessary rather than advisable.

Most travellers pass through rather than stay, usually en route between Karatu and Lake Eyasi or heading south toward Singida. Any month serves that purpose in a capable vehicle, though the dry season makes it considerably easier.

FAQ

Frequently asked questions

What is Mbulu known for?

It is the heartland of the Iraqw, a Cushitic-speaking people whose language is unrelated to Swahili or Maa, making this pocket of northern Tanzania linguistically distinct. The surrounding highlands are terraced and intensively farmed in a pattern found nowhere else on the circuit, and traditional tembe homesteads, built partly below ground with earth roofs, survive in the countryside. Most visitors base themselves in Karatu, an hour away, which has a far wider choice of lodges and farm stays.

Is Mbulu worth visiting?

Honestly, only for travellers with their own vehicle exploring the highlands between Karatu and Lake Eyasi, or with a specific interest in Iraqw culture and highland farming. There is very little tourism infrastructure and no organised programme. Visitors making a dedicated journey here will find it thin, and the surrounding countryside is more interesting than the town itself. A 4x4 is advisable outside the dry season, as the unsealed approach roads deteriorate quickly after rain.

How do I get to Mbulu?

It lies roughly 50 kilometres south-west of Karatu on unsealed roads that deteriorate during the rains, taking one to two hours depending on conditions. A 4×4 is advisable outside the dry season. Buses run from Karatu and Arusha but are slow. Most visitors come with their own transport as part of a wider highland route. The surrounding countryside is considerably more interesting than the town itself, which is small and functional.

Who are the Iraqw?

They are a Cushitic-speaking people numbering several hundred thousand, concentrated around Mbulu and the Karatu highlands, whose language belongs to the Afroasiatic family and is quite unrelated to those of their Bantu and Nilotic neighbours. They are highland farmers rather than pastoralists, and their terraced cultivation and distinctive homestead architecture set them apart in the region. Most visitors base themselves in Karatu, an hour away, which has a far wider choice of lodges and farm stays.

How cold does it get?

Colder than most visitors expect for northern Tanzania. At around 1,700 metres, days reach only 21°C to 26°C and nights fall to 9°C to 14°C, with June and July the coldest. Accommodation is basic and rarely heated. Anyone arriving from the Rift Valley floor or the coast should pack a warm layer, as the contrast is considerable. A 4x4 is advisable outside the dry season, as the unsealed approach roads deteriorate quickly after rain.

Where should I stay?

Mbulu has only basic guesthouses aimed at travelling traders and officials rather than visitors. Most people exploring this area base themselves in Karatu, an hour away, which has a wide spread of lodges and farm stays, and make day trips into the Mbulu highlands from there. That is the practical arrangement for anyone wanting any degree of comfort. The surrounding countryside is considerably more interesting than the town itself, which is small and functional.

When is the best time to visit?

June to October is dry and clear, with the firmest roads and the most comfortable conditions for walking in the surrounding farmland, though nights are cold. December to February is warm and largely dry. March to May brings the long rains, when the unsealed approach roads deteriorate considerably and a 4×4 becomes necessary rather than merely advisable. Most visitors base themselves in Karatu, an hour away, which has a far wider choice of lodges and farm stays.

Can I combine Mbulu with Lake Eyasi?

Yes, and it is the most sensible way to visit. The road south-west from Mbulu drops toward Lake Eyasi and the Hadzabe country, so the two can be combined into a highland-to-lowland route with a capable vehicle. Both are usually approached from Karatu, which serves as the practical base for the whole area. A 4x4 is advisable outside the dry season, as the unsealed approach roads deteriorate quickly after rain.
