The three sisters caves are about 15 kilometres from the Kenana-Shimoni junction.
The caves are; Pangani, Kisimani and Mdenyenye and all have cultural artefacts of the Digo people.
Mdenyenye Cave is the largest with a wooden staircase built by the locals. History has it that this cave was specifically used as a hideout for the villagers who were running away from slave traders.
Pangani cave has several chambers that were used for prayers and rest. It is believe that their ancestors also had their meals in the Pangani cave. Pangani is unique since it that it has an underground tunnel stretching about a record six kilometres and it connect to the Shimoni caves. However reports suggest that it has unfortunately been blocked and it is impassable now. The slaves used to run away from Shimoni using this tunnel.
Kisimani Cave (Swahili for a well) has a freshwater well that never runs dry. This is an important site where visitors can spot wildlife such as baboons and monkeys as they quench their thirst. This cave is also home to thousands of bats of atleast seven known species such as the Egyptian fruit bats, common bent-wing, long-fingered bats, tomb bats, as well as angle-faced bat.
The three caves are managed by a community-based organisation and opens its doors to local and foreing tourists at an affordable fee.
