About Pulau Siamil Lighthouse

Also known as: Pulau Siamil (Si Amil)

A cylindrical steel tower, 11 meters tall and painted with red and white horizontal bands, stands on Pulau Siamil. Its light emits a single white flash every 15 seconds. The focal height of the light is 107 meters, providing a geographic range of 25.6 nautical miles. This lighthouse replaced an earlier skeletal tower in 1952. The site is accessible to visitors by boat, though the tower itself is closed to the public. The nearest port is Labuan Haji, located 18.1 kilometers away.

Why it matters: This lighthouse marks the southern entrance to the Alice Passage, a critical route for vessels transiting the Celebes Sea and aids in the safe passage of commercial and fishing craft.
