About Isla Barlovento Lighthouse

Located on a remote island south of Cape Horn, the Isla Barlovento lighthouse guides vessels through a channel separating Chilean and Argentine waters. The structure is a cylindrical fiberglass tower, 8 meters tall and painted white with a single red horizontal band. Its light, positioned 11 meters above sea level, emits a white flash every 5 seconds and has a geographic range of 10.7 nautical miles. The site is open for visitors to explore the island, though the tower itself remains closed to the public. This active light is situated directly opposite the Isla Martillo light on the Argentine side of the channel.

Why it matters: This lighthouse is essential for safe navigation through the channel it marks, serving as a critical guide for vessels moving between Chilean and Argentine waters. Its modern fiberglass construction represents a practical and durable solution for a remote, exposed location.
