About Isla Negritos Lighthouse

This steel skeletal tower stands 12 meters tall, painted with red and white horizontal bands. It is situated at the eastern end of Isla Negritos, marking a dangerous reef system extending from the west side of the Gulf of Nicoya. The light emits a single white flash every 20 seconds, visible for over 18 nautical miles. Built in 2011, it serves as a marker for vessels navigating east of Paquera. Despite its operational status, it was dropped from Admiralty and NGA lists in the same year it was established.

Why it matters: The lighthouse warns mariners of the extensive reef system surrounding the Islas Negritos, a critical navigational hazard in the western Gulf of Nicoya.
