Simbo Island, historically known as Mandegusu, is a compelling volcanic island in the Western Province of the Solomon Islands. The island is composed of two primary volcanic cones and is distinct for its persistent geothermal activity, including boiling hot springs and active fumaroles. Historically, Simbo was a paramount center for traditional spirituality and culture in the western region, particularly renowned for its elaborate headhunting rituals and ancestor worship. The island is home to several 'skull houses', small stone shrines that contain the skulls of esteemed ancestors and defeated enemies. These sites reflect the profound spiritual connection the inhabitants maintain with their warrior heritage and ancient religious observances. The social fabric of the island was historically governed by powerful chiefs who monopolized the trade of shell money and other high-status commodities. In 2007, Simbo was severely impacted by a massive earthquake and subsequent tsunami, which forced significant relocations and structural changes to the villages. Today, the island serves as a place where traditional customs are carefully balanced with the demands of modern life. Its unique geological features and dense historical legacy make Simbo a site of great interest for both geologists and anthropologists.

Photography

Photography is allowed in most places, but avoid photographing sacred sites or ceremonies without permission. The volcano gives great opportunities for landscape shots, especially in the good light of early morning.
