Since we are stuck in Tanzania with basically nowhere to go, we decided to explore every tiny little bit of this mesmerizing country.

This time, we went deep into the guts of the earth, to a place that is definitely not tiny.
The Amboni Caves are the largest limestone caves in East Africa, a complex of ten interconnected caves covering an area of about 234 km², although no one exactly knows how big this underground labyrinth is.
History of the Amboni Caves
The caves were formed about 150 million years ago during the Jurassic age. According to researchers, the area was underwater some 20 million years ago.
It is not known when the caves were first discovered and used by humans. Reports indicate that ethnic groups such as the Segeju, Sambaa, Bondei, and Digo who lived near the caves used it for ritual purposes.
They were rediscovered in the late 19th century by Amboni Limited, which had acquired mining rights to the land.
The company notified the discover to the colonial authority, which made it a conservation area in 1922.
During the struggle for independence from the British Empire, guerrilla fighters used the cave as a hideout. They found niches on the surface where they could light fires.
Some years ago, a foreigner tried to explore the caves’ unknown depths alone, accompanied by his dog. He was never seen again, and the dog was later found in Tanga.
Curiosities and Peculiarities of the Amboni Caves of Tanga
The Amboni Caves are inhabited by thousands ofPopo (bats in Swahili). Every evening, at sunset, they fly out of the cave entrance in a very fascinating display.
Besides the thousands of bats, these caves have many interesting features that have stimulated people’s imagination for thousands of years. And they still do nowadays.
Rocks are said to resemble the shapes of a sofa, a ship, a crocodile, an elephant, a map of Africa, the Statue of Liberty, the Arab alphabet, a male lion’s head, a penis, and a vagina.
According to our guide, you can reach Mombasa, in Kenya, via this underground natural maze.
How to get to Amboni Caves
The caves are located just 8km from Tanga, just off the main road to the Kenyan border toward Mombasa. From Tanga, it is also possible to reach Pemba Island and Zanzibar by boat.
Reaching them with your own means of transport is very easy, as their location is marked on all the most popular mapping applications.
Be careful, though, as the last kilometer is off-road and pretty rough for a low-clearance vehicle.
Alternatively, you can take a Tuk-Tuk or a motorbike from downtown and agree on the price in advance. They shouldn’t charge you more than 5,000 shillings.
The entrance to the caves is located in a beautifully forested area, flanked by an emerald-green river. Unfortunately, you are apparently not allowed to swim there.
The reason, allegedly, is the presence of crocodiles (highly unlikely, IMHO). The real reason is probably not to have people doing stupid things and breaking their bones on a slippery rock.
Costs of Amboni Caves – entry fees and guide
As it unfortunately happens pretty often in Tanzania, the entry fee for the Amboni Caves is a bit overpriced for non-residents.
- 25,000 Tsh + mandatory guide
The guide fee should actually be included in the price, but you’ll be insistently asked for a tip from your guide. 5/10,000Tsh is reasonable.
