Kilu Cave

Kilu Cave is a limestone cave located at the base of a cliff on Buka Island that contains layered archaeological deposits and natural stone formations. The site displays multiple levels of sediment that record thousands of years of human activity within its chambers.

The cave was first inhabited by early humans around 30,000 years ago and contains evidence of one of the oldest known human presences in the region. This ancient occupation demonstrates that people were already making complex journeys across water at this very early time.

Archaeological excavations at Kilu Cave reveal ancient tools, pottery fragments, and evidence of early plant usage, including taro and coconut cultivation.

Access to the cave requires a local guide since the trails are challenging and knowledge of the best route is essential. Visitors should bring sturdy footwear and bring a flashlight or headlamp to explore the dark interior sections safely.

Artifacts found in the cave show that early inhabitants used plants like taro and coconut, suggesting a sophisticated understanding of the local environment. These botanical traces are rare evidence of how ancient communities organized and managed their food sources.
