Historically, Kwale Island was home to the Wadiko tribe, who lived along the coastal regions. In response to attacks by Masai warriors. The Wadigo from Mwandusi village sought refuge on Kwale Island, which provided a safe haven as the Masai were afraid to cross into the Island. However, a lack of fresh waters and the growing size of their communities forced the Wadigo to return to the mainland, with many settling in Kwale village. During both world wars, the island served as a strategic fortress.
Today, Kwale Island is covered in dense vegetation, featuring towering baobab trees, extensive mangrove swamps, and thick thorn bushes. Unfortunately, the absence of formal legal protection has resulted in deforestation, as locals are cutting down trees for firewood. The island also bears historical significance, evidenced by remnants of Swahili pottery dating back to the Middle Ages, indicating that it once belonged to the Swahili states. Since then, it just remained largely uninhabited.
