Amboni Caves (Mapango ya Amboni in Swahili) are a limestone cave complex located in Kiomoni ward, about 8 km north of Tanga city center along the Tanga–Mombasa road. Formed roughly 150 million years ago during the Jurassic age, the caves cover an area of 234 km². Researchers believe the area was once underwater around 20 million years ago. Of the ten caves in the complex, only one is currently open for guided tours, making it the main attraction for visitors.
The caves were acquired in 1892 by Amboni Limited, a company operating sisal plantations in the region. In 1922, the British colonial government declared the caves a conservation area. Local ethnic groups such as the Segeju, Sambaa, Bondei, and Digo are known to have used the caves for prayers and rituals long before formal recognition. In 1963, after independence, the caves were handed over to the Department of Antiquities, ensuring their preservation as a cultural and natural heritage site.
Amboni Caves lie just outside Tanga city, making them easily accessible for day trips. The surrounding landscape includes coastal forests, sisal plantations, and rural villages. Their proximity to Tanga’s port and historic sites such as Tongoni Ruins and Toten Island makes the caves part of a broader cultural and eco-tourism circuit in the region.
