Shimoni is a small town known for its British colonial ruins and slave caves which are the focus of attraction for several community-based projects. In addition, the Shimoni forest, coast, and marine ecosystems are an ever-present attraction. Kenya Wildlife Service's headquarters for the Kisite-Mpunguti Marine Protected Area is located in Shimoni.
The Shimoni Caves were a sacred site used by Kaya elders for sacrifices and prayers before the invasion of slavery in the 8th Century. The Arab Slave Traders then used the caves as a slave pen until the 19th Centuries. Rusted chains and metal studs, old iron shackles, and wooden crates have been preserved in the caves to tell the sad stories of the African slave trade victims.The 5km long Caves are opened daily from 8am to 6pm for visiting at a fee.
Shimoni's other touristic attractions include scuba diving centers such as Pilli Pippa and Paradise Divers (located in Mkwiro) which take divers within and outside protected marine areas at Kisite-Mpunguti Marine National Park.
