Adventure tourism: Visit the Amboni Caves in East Africa
The Amboni Caves are the most massive limestone caves in East Africa. They are placed eight km north of Tanga City in Tanzania off the Tanga-Mombasa road.
The caves have been shaped about one hundred fifty million years in the past at some stage in the Jurassic age. It covers an location of 234 km². According to researchers the region used to be below water some 20 million years ago. There are altogether ten caves however solely one is used for guided tours.
Amboni Limited, a company which was then operating sisal plantations in Tanga Region acquired the area in 1892. The company notified the British colonial government about the caves who in turn declared the caves a conservation area in 1922.
It is not known when the caves were exactly discovered but reports indicate that ethnic groups such as the Segeju, Sambaa, Bondei and Digo who lived near the caves used it for prayers. In 1963, the then government of Tanganyika handed over the caves to the Department of Antiquities.
These caves have been subject of local legends and a number of mythical and awe-inspiring stories have been attributed to the caves. To the local people the caves are regarded as supernatural formations where supernatural powers commonly known as “Mizimu” are believed to have been residing since the caves formation.
There are chambers treated as sacred chambers for worshiping some spirits. One of them is called “Mzimu wa Mabuvu”. Some believe that there is a powerful deity which can alleviate their sickness, sufferings or increase their fertility.
These limestone caves are formed by a special nature of erosion. According to Mturi (1975:18-19), there are tree theories which explain the formation of the Amboni Caves. The first theory is known as the vedose process.
According to this theory, rain water absorbs carbon dioxide in the atmosphere and forms a weak carbonic acid which is capable of dissolving calcium carbonate minerals of which limestone is formed. When this acidulated rain water seeps trough the limestone it is dissolved and cavities and caves are formed.
The second theory is that of phreatic origin. According to this theory, the caves are formed by erosion from the sub water table. The rain water with carbonic acid rapidly seeps through the limestone and reaches the water table before being a saturated solution of calcium bicarbonate. At this stage it is still capable of acting as a dissolving agent for the calcium carbonate.
The Amboni caves are believed to be the most extensive limestone caves in East Africa, located in Kiomoni village. The caves, a one and half kilometer stretch, are a fascinating historical site, which were used as hiding places for the locals.

The Amboni caves are among the area’s most popular attractions and feature vast below-ground halls with towering formations. Visitors are advised to wear comfortable shoes and to bring a pocket-size camera, since it’s cumbersome to bring a camera with a large lens as walking is through tight squeezes. And before entering some of the tight spots, visitors are asked to leave large bags in an area to pick up later.
